*STATE OF LOUISIANA, Complainant,
v.
STATE OF MISSISSIPPI.
(See S. C. Reporter’s ed. 1-59.)

1. Controversy between states — origi¬

nal jurisdiction ot Supreme Court. —
A conflict between the authorities of the states of Louisiana and Mississippi, aris¬ ing out of the enforcement of the oyster legislation of those states, which involves a dispute respecting the true boundary line, creates a controversy between the states in their sovereign capacity, which is within the original jurisdiction of the Supreme Court of the United States.

2. Congress — power to niter state

boundaries.— Congress, after the admission of Louisiana into the Union, could not take away any portion of that state in admitting Mississippi to the Union, and give it to the latter state.

8. Statutes — construction — in pari ma¬

teria. — The doctrine in pari materia cannot be invoked to establish a preconcerted de¬ sign by Congress, in the several enactments providing for the admission, respectively, to the Union, of the states of Louisiana, Mississippi, and Alabama, to equalize the water frontage of those states on the Gulf of Mexico, — especially in view of the fact that, when Louisiana was admitted intp the Union, the territory now composing the coast counties of Mississippi was not actually a part of the Mississippi territory, but was in dispute between the United States and Spain.
4. Boundaries between states — Islands.
—The chain of sea-sand islands running from the west shore of Mobile bay, in the state of Alabama, westward to, and inclusive of, Cat island, in the state of Mississippi,

and not the sea-marsh islands previously granted to the state of Louisiana, was meant by the provision in the Mississippi enabling act of March 1, 1817 (3 Stat. at L. 343, chap. 23, § 2), establishing the southern boundary of the proposed state as extending westwardly from the intersection of the eastern boundary with the Gulf of Mexico,, “including all the islands within 6 leagues* of the shore,” to the most eastern junction of Pearl river with Lake Borgne.
5. Boundaries between states— Islands.
—All islands within 9 miles of the coast line of the Louisiana marshes at the eastern extremity of St. Bernard peninsula, except as restricted hy the deep-water sailing chan¬ nel, regarded as the boundary between the states of Mississippi and Louisiana, were granted to the latter state by the act of April 8, 1812 (2 Stat. at L. 701, chap. 50). admitting Louisiana into the Union, with a boundary described as extending along the middle of the Iberville river and Lakes Maurepas and Pontchartrain to the Gulf of Mexico, and thence bounded by said gulf to the mouth of the Sabine river, “including: all islands within 3 leagues of the coast.”’
6. Boundaries between states — thalweg.
—The deep-water sailing channel or “thal¬ weg” emerging from the most eastern mouth of Pearl river into Lake Borgne and extend¬ ing through the northeast corner of Lak6 Borgne, north of Half Moon or Grand island, thence east and south through Mississippi sound, through South pass, between Cat is¬ land and Isle a Pitre to the Gulf of Mexico, is the true boundary line between the states of Mississippi and Louisiana, under the act of April 8, 1812, admitting Louisiana into the Union, with a boundary described as ex¬ tending along the middle of the Iberville riv¬ er and Lakes Maurepas and Pontchartrain
to the Gulf of Mexico, and thence bounded by the said gulf to the mouth of the Sabine river.

boundary, and the exercise of dominion and sovereignty over the territory within it, should be accepted as conclusive, whatever the international rule may be in respect to the acquisition by prescription of large tracts of country claimed by both states.
[No. 11, Original.]
'Argued October 10, 11, 12, 1905. Decided March 5, 1906. Final decree entered, April 23, 1906.
ORIGINAL SUIT in equity to settle a disputed boundary line between the states of Mississippi and Louisiana in the waters of Lake Borgne and Mississippi sound. Boundary decreed as being the deep¬ water channel sailing line emerging from the most eastern mouth of Pearl river into Lake Borgne, and extending through the northeast corner of Lake Borgne, north of Half Moon or Grand island, thence east and south through Mississippi sound, through South pass, between Cat island and Isle a Pitre, to the Gulf of Mexico.
Statement by Mr. Chief Justice Fuller: The state of Louisiana, by leave of court, filed her bill against the state of Missis¬ sippi, October 27, 1902, to obtain a decree determining a boundary line between the two states, and requiring the state of Mis¬ sissippi to recognize and observe the line so determined.
The bill alleged:
“1st. That the state of Louisiana was admitted into the Union of the United States of America by the act of Congress found in chapter 50 of the United States Statutes at Large, vol. 2, page 701, ap¬ proved April 8th, 1812, and therein the boundaries of the said state of Louisiana, in the preamble of said act, were described -as follows : —
‘Whereas, the representatives of the peo¬ ple of all that part of the territory or coun¬ try ceded under the name of “Louisiana,” by the treaty made at Paris on the 30th day of April, 1803 [8 Stat. at L. 200], be¬ tween the United States and France, con¬ tained within the following limits, that is
(no text on this page in the source reporter)
to say : Beginning at the mouth of the *r i ver Sabine, thence by a line drawn along the middle of said river, including all islands to the 32d degree of latitude; thence due north to the northernmost part of the 33d degree of north latitude; thence along the said parallel of latitude to the River Mis¬ sissippi; thence down the said river to the River Iberville, and from thence along the middle of said river and Lakes Maurepas and Pontchartrain to the Gulf of Mexico; thence bounded by the said gulf to the 914
place of beginning, including all islands within three leagues of the coast,’ etc.
“2nd. That according to the foregoing description, the eastern boundary of the state of Louisiana was formed by the Mis¬ sissippi river, beginning at the northeast corner of said state and extending south to the junction of the said river with the River Iberville (now known as Bayou Man- chac), and thence extending eastwardly through the lower end of the Amite river, through the middle of Lake Maurepas, Pass Manchac, and Lake Pontchartrain, and in order to reach the Gulf of Mexico its only course was through the Rigolets, into Lake Borgne, and thence by the deep-water chan¬ nel through the upper corner of Lake Borgne, following said channel, north of Half Moon island, through Mississippi sound to the north of Isle & Pitre, through the Cat Island channel, southwest of Cat island, into the Gulf of- Mexico, which said eastern boundary of the state of Lou¬ isiana is more fully shown on diagram No.
1, made part of this bill. [See post.]
“3rd. That by the act of Congress found
in the United States Statutes at Large, vol.
2, p. 708, chap. 57, approved April 14th, 1812, additional territory was added to the then-existing state of Louisiana which addi¬ tional territory was described in the follow¬ ing language: —
‘Beginning at the junction of the Iberville with the River Mississippi; thence along the middle of the Iberville, the River Amite, and of the Lakes Maurepas and Pontchar¬ train to the eastern mouth of the Pearl river; thence up the eastern branch of Pearl river to the 31st degree of north latitude; thence along the said degree of latitude to the River Mississippi; thence *down the said
river to the place of beginning, shall become and form a part of the said state of Lou¬ isiana.’
“4th. That the effect of this legislation, as to the eastern boundary of the state of Louisiana, was to retain the Mississippi river as the original eastern boundary, as far south as the 31st degree of north lati¬ tude. The change then moved the eastern boundary eastward along the 31st degree of north latitude to the Pearl river, whence it then ran south down the said river, through its eastern branch, till it entered the northern corner of Lake Borgne, where the state’s eastern boundary then joined and followed the boundary line originally fixed in the act of April- 8th, 1812, and followed, as heretofore stated, *the deep-water channel
through the upper corner of Lake Borgne, north of Half Moon island,- eastward through the deep-water channel along the Mississippi I sound till it reached the Cat island channel

north of Isle a Pitre, and southwest of Cat island, whence passing through Chandeleur sound, northeast of Chandeleur islands, it en¬ tered the Gulf of Mexico, and ran south around the delta of the Mississippi river and then north and westward to the point where the Sabine river enters the Gulf of Mexico, as will be more fully seen from the diagram No. 2, made part of this bill. [See post.] “5th. That the territory lying adjacent to, and to the eastward of, the state of Louisiana, is the state of Mississippi, which
‘latter 'state was admitted into the Union of
the United States of America by the act of Congress found in the United States Statutes at Large, vol. 3, chap. 23, page 348, approved March 1st, 1817, whereby the inhabitants of the western part of the then Mississippi territory were authorized to form for themselves a state constitution and to be admitted into the Union, the boundaries of the tlien-to-be-created state being described as follows: —
‘Beginning on the River Mississippi at the point where the southern boundary line of the state of Tennessee strikes the same; thence east along the said boundary line to the Tennessee river; thence up the same to the mouth of Bear creek; thence by a direct line to the northwest corner of the county of Washington [Alabama] ; thence due south to the Gulf of Mexico; thence westwardly, including all the islands with¬ in six leagues of the shore to the most east¬ ern junction of Pearl river with Lake Borgne; thence up said river to the 31st degree of north latitude; thence west along the said degree of latitude to the Mississippi river; thence up the same to the beginning.’
“6th. That by the said act, Congress in¬ tended that the southern boundary line of the state of Mississippi, beginning at the point dividing it from the state of Alabama, should run westwardly till it joined the Louisiana eastern boundary line, and that, in doing so, the said southern boundary would in effect start westward from a point 18 miles south of the coast line, and include in its westwardly direction the western end of Petit Bois island, all of Horn island, Ship island, and Cat island, and the smaller islands north of these, those islands being the ones contemplated in the act of Con¬ gress, as being within 18 miles of the south¬ ern coast line of Mississippi, and that the said southern boundary of Mississippi, ex¬ tending in its westwardly direction through the Gulf of Mexico, would gradually ap¬ proach the coast line, and meet the eastern boundary line of Louisiana, just as the said eastern boundary line of Louisiana emerges from the Cat Island channel into the Gulf of Mexico, and thence follow and
become £he same as the ‘Louisiana boundary 202 U. S.
line extending westwardly to the south of Cat island, through Mississippi sound to the north of Half Moon or Grand island to the most southern junction of the *east
branch of the Pearl river with Lake Borgne, being identical with the Louisiana eastern boundary, and thence extending up the channel of Pearl river.
“7th. That the islands included between the shore line and the southern boundary of the state of Mississippi are the islands here¬ tofore described, viz. : the western end of Petit Bois island, with all of Horn island, Ship island, and Cat island, and the small islands north of them, those islands being large, and well known to Congress at the time of the passage of the act, all of which islands and the southern boundary of the state of Mississippi will more fully ap¬ pear from the diagram No. 3, made a part of this bill. [See post.]
“8th. That the islands contemplated in the act of Congress of [April 8] 1812, creat¬ ing the state of Louisiana, and intended to be embraced within the state of Louisiana, as provided by the clause, ‘Thence bounded by the said gulf to the place of beginning, including all islands within three leagues of the coast,’ were all of the other islands, except those heretofore named as going to the state of Mississippi, as all other islands, and all other mainland, are south and west of the boundary line thus passing from Pearl river through the deep-water channels in Lake Borgne and Mississippi sound, through the deep-water channel southwest of Cat island to the eastward of the Chan¬ deleur islands, and thence south, taking in the delta of the Mississippi river, and ex¬ tending westward along the Gulf coast, in¬ cluding all islands along the coast, to the Sabine river, where the state of Louisiana is thence bounded on the westward by the state of Texas, all of which will more fully appear from diagram No. 2, heretofore re¬ ferred to.
“9th. Now your orator avers that there has developed in recent years in the waters south of the state of Mississippi and east of the southern portion of the state of Lou¬ isiana a considerable growth of oysters, and an industry of large proportions, in the handling of said bivalves, either in their fresh or in a canned condition, has resulted therefrom.
“10th. That the state of Mississippi has by legislative ‘enactments regulated the oys-
ter industry in the waters of said state, and permits the dredging of oysters on the natural oyster reefs in waters of the said state, as- will more fully appear from the statutes of said state to which reference is made.
“11th. That the state of Louisiana has,

by legislative enactments, regulated the oyster industry in the said state of Lou¬ isiana, and prohibits the dredging of oysters on the natural reefs in the waters of said state, as will more fully appear from the statutes of said state to which reference is made.
“12th. That the provisions of the laws of the said, two states differ considerably in many other respects.
“13th. That the existence and location of the natural oyster reefs in the waters of the parish of St. Bernard, in the state of Louisiana, which adjoins the state of Mis¬ sissippi, is shown by the map made from a reconnaissance by the United States Fish Commission steamer ‘Fish Hawk,' in Feb¬ ruary, 1898, as will more fully appear from diagram No. 4, now made part of this bill. [See post.]
“14th. Now your orator avers that the boundary line dividing the two states in the waters thereof has been clearly defined by the acts of Congress creating the states of Louisiana and Mississippi, as will be seen from the diagram No. 5, made up from the boundary descriptions taken from the acts of Congress creating the said states of Lou¬ isiana and Mississippi, which diagram is also made part of this bill. .[See post .1
“15th. That the said boundary line in the waters between said states has never been designated by buoys or marks of any kind by either state, nor designated in any man¬ ner, except by the United States government in so far as it has buoyed the deep-water channel, extending from the mouth of ( the Pearl river through the upper corner of Lake Borgne, north of Half Moon island, eastward to the Cat Island pass, north of Isle ft Pitre, and southwest of Cat island, which buoys were placed by tlie Coast Sur¬ vey of the United States government.
“16th. That owing to the differences in the laws of the states of Louisiana and Mis¬ sissippi, regulating the oyster industry of
•
the respective states, the said statutes pro¬
viding penalties for the violation thereof, much confusion has resulted, and a great public demand has arisen in Louisiana to definitely mark the boundary line dividing the two states in the waters thereof; that citizens of the state of Mississippi, in vio¬ lation of the laws of the state of Louisiana,
ha,ve been fishing oysters with dredges *on the natural reefs in the waters of the state of Louisiana, said fishermen claiming that they were in the waters of the 'state of Mis¬ sissippi, and consequently not violating the laws of the state of Louisiana.”
The bill then set forth that “to avoid an armed conflict between the sheriff and offi¬ cers of the parish of St. Bernard, in the state of Louisiana, and the sheriff and offi- 016
cers of the county of Harrison in the state of Mississippi,” a meeting of citizens of Louisiana was called by the governor of that state, which met in New Orleans, and resulted in the appointment by the governor of commissioners on the part of Louisiana “to consider the determination of the water boundary line between the two states, and arrange for its easy location and identifi¬ cation by a proper system of buoys,” and the request that the governor of Mississippi appoint like commissioners on the p^rt of that state, which appointment was made.
The joint commission met and considered the subject, and subsequently the Mississippi commission reported its inability to agree with the Louisiana commission, stating, among other things, “It is apparent that the only hope of settlement is a friendly suit in the Supreme Court of the United States, and we respectfully suggest that course.”
The bill continued:
“24th. That the eastern water boundary line, as claimed by your orator, viz., a line beginning at the most southern junction of the channel of the east branch of the Pearl river with Lake Borgne, and thence east¬ ward, following the deep-water channel to the north of Half Moon island, through the Mississippi Sound channel, to Cat Island pass, northeast of Isle ft Pitre into the Gulf of Mexico, thereby dividing the waters be¬ tween the two states, agrees, and is in ac¬ cord, with the acts of Congress creating re¬ spectively the state of Louisiana and the state of Mississippi, as already shown by diagram No. 5; that any other boundary than the deep-water channel as aforesaid would cause the limits of the two states to conflict and overlap, and that it is not to be presumed that the Congress of the LTnit- ed States 'intended to, or would, establish,
in its description, a boundary for the state of Mississippi, conflicting with the already- existing Louisiana eastern boundary, when there is a construction of the wording of the two acts, in fact, the only construction that suggests itself, that shows a boundary read¬ ily ascertained, harmonizing with the words of the acts as they now read, and clearly defining the limits of the two states in the waters between them.
“25th. Your orator further avers that the use of the word ‘westwardly’ in the de¬ scription of the southern boundary of the state of Mississippi, as that southern bound¬ ary line extends westwardly from the Ala¬ bama state line to the Louisiana eastern boundary line, shows that it was not the intention of Congress to have it run direct or due west throughout the whole course, and that it was evidently the intention of Congress, in giving to the state of Missis-

sippi the islands north of that westwardly- drawn line, that the 18-mile limit shall gradually decrease as it approached the Louisiana line on the east, till it met and followed it to its source. If the Missis¬ sippi line ran parallel to the southern coast of Mississippi, at a distance of 18 miles from such coast line, following the meander of the coast, and thence joined at right angles a line emerging from the mouth of Pearl river, such line would not only in¬ clude Grassy, Half Moon, Round, Le Petit Pass islands and Isle 3 Pitre, already be¬ longing to Louisiana as being within '9 miles or 3 leagues of the Louisiana shore line, but such line would also include part of the mainland of the state of Louisiana, as will be seen from the following diagram (No. 6), made a part of this bill, and it cer¬ tainly could not have been the intention of Congress to take away from the state of Louisiana any islands or mainland already belonging to it, and to give them to the state of Mississippi, as such a proceeding, without the consent of the legislature of the state of Louisiana, would be a violation of § 3 of art. 4 of the Constitution of the United States.
“26th. Your orator avers that the marsh
lands claimed by *the state of Mississippi to be islands are in truth, with the excep¬ tion of the Isle 3 Pitre, Grassy, Half Moon, Round, and Le Petit Pass islands, low-ly¬ ing marsh lands, forming part of the main¬ land of the state of Louisiana; that said swamp or marsh lands and islands have been known as and called, since time imme¬ morial, ‘the Louisiana marshes;’ that they were approved to the state of Louisiana by the Commissioner of the General Land Office on May 6, 1852, as will appear from a cer¬ tified copy of said record of approval from the United States Land Office, made a part of this bill, marked Exhibit (G) and, where not since sold by the state of Louisiana to private purchasers, have always stood on the books of the register of the Louisiana state land office as state lands, to be offered for sale, until recently transferred by the state of Louisiana to the board of commis¬ sioners for the Lake Borgne basin levee district by the provisions of act No. 14 of the legislature of the state of Louisiana for the year 1892, for the purpose of ena¬ bling the said levee board, by the proceeds of sale of said lands, to secure the funds to aid in the building of levees in that levee district, to protect the lands from overflow.
“27th. That parts of said disputed terri¬ tory claimed by the state of Mississippi to be islands within 18 miles of its shore line are in fact part of the mainland of the state of Louisiana, and therefore belong to and form part of said state of Louisiana; but 202 U. S.
if your Honors should feel that any part of this disputed area was islands by reason of the presence of shallow water, then, as islands, they are within the 9-mile limit of distance from the shore line of the state of Louisiana, and therefore belong to and form part of the state of Louisiana by that sec¬ ond provision of th^ act of Congress giving Louisiana all islands within 3 leagues of its shore line.
28th. Your orator further avers that where contiguous states or countries are separated by water it is, and always has been, the custom to regard the channel as establishing the boundary line of such states, and that the state of Mississippi has itself recognized this principle in the de¬ scription of .*its territorial limits, as found
in the 2d article of its own Constitution, adopted November, 1890, in the following words :
“29th. Your orator avers that, as hereto¬ fore stated, the Congress of the United States, as well as the various departments of the United States government having au¬ thority in the premises, have themselves recognized the boundary line contended for by the state of Louisiana by reason of the fact that the United States government has confirmed to the state of Louisiana the lands composing Half Moon island, which is just south of the deep-water channel” [by sections and townships as set forth] and also “the lands forming what is commonly known as Isle 3 Pitre” [by sections and townships, as stated], all of them “recog- nized as belonging to and forming part of the state of Louisiana by the said United States government, and have always hereto¬ fore been so recognized by the people of the said two states; that the lands forming the Isle 3 Pitre were sold by the state of Louisiana,” etc., etc., “and said lands have been assessed on the assessment rolls of the parish of St. Bernard, state of Louisiana, and taxes thereon have been paid to the state of Louisiana for the past thirty-five years, and said lands have never been assessed on the rolls of, nor have any taxes ever been paid to, the state of Mississippi, and that this is the case with all other lands and islands now claimed by the state of Missis¬ sippi, but which in truth and fact belong to the state of Louisiana.”
“30th. Your orator therefore further avers that all constituted authorities com¬ petent to create, adopt, or consider the said boundary line have declared the water boundary line claimed by the state of Louisiana, viz., the deep-water channel running from the most southern junction of the eastern mouth of Pearl river, through Lake Borgne, north of Half Moon island,

through Mississippi sound, north of Isle ft Pitre, and southwest of Cat island, through Cat Island pass, through Chande- leur sound northeast of Chandeleur islands
to the Gulf *of Mexico, to be the true water boundary between the said states.”
The bill prayed that it be adjudged and decreed “that the boundary line dividing the states of Louisiana and Mississippi, in the waters between the said states to the south of the state of Mississippi, and to the southeast of the state of Louisiana, is the deep-water channel, commencing at the most southern junction of the eastern mouth of Pearl river with Lake Borgne, thence by the deep-water channel through Lake Borgne, north of Half Moon island, through Mississippi sound, north of Isle ft Pitre, through Cat Island Pass channel, southwest of Cat island, through Chandeleur Island sound, northeast of the Chandeleur islands, to the Gulf of Mexico, as is delineated on the original map submitted by the Louis¬ iana boundary commission to the Missis¬ sippi boundary commission, and now made part of this bill, marked Exhibit ‘E;’ that the said deep-water channel be located throughout its course and permanently buoyed at the joint expense of the two states; that the state of Mississippi and its citizens be perpetually enjoined from disput¬ ing the sovereignty and ownership of the state of Louisiana in the said land and water territory south and west of said boundary line,” and for costs and general relief.
[Exhibit “E” is not reproduced in the printed record, but it to be found in the Louisiana Atlas of Maps, p. 60. It con¬ sists of coast survey charts Nos. 189, 190, and 191, showing the coast from Mobile to Lakes Borgne and Pontehartrain, with boundary lines added in red ink. The maps given in this statement are sufficient to supply the lack of this particular exhibit.]
The state of Mississippi, by leave, filed a demurrer to the bill, which was, by stipu¬ lation, submitted to the consideration of the court on printed arguments, and was sub¬ sequently overruled.
Thereupon the state of Mississippi, on leave, filed her answer and cross bill.
*The state denied articulately nearly every material allegation of the bill, and there¬ fore the accuracy of the diagrams or maps attached thereto, and asserted the true boundary to be as set forth in her cross bill. And while she admitted “that the deep¬ water channel out of the mouth of Pearl river, through the upper course of Lake Borgne, and on into the Gulf, as stated in the bill, has been marked by buoys by and under the direction of the United States government, for navigation and commercial 918
purposes, ” she denied “that said marking of the deep-water channel was ever intend¬ ed to fix in any manner whatsoever any part of the boundary line between said states,” and further denied “the correctness of complainant’s statement that where con¬ tiguous states or countries are separated by water, the channel of the waters dividing said states constitutes a boundary line, and defendant specifically denies that such rule is applicable to this case.”
The cross bill averred that the southern boundary line of the state of Mississippi was fixed by the act of Congress, approved March 1, 1817, 3 Stat. at L. 348, chap. 23,
§ 2.
That by that act Mississippi was given “all lands under the waters south of her well-defined shore line to the distance of six leagues from said shore at every point between the Alabama line and the most eastern junction of Pearl river with Lake Borgne, including all islands within said limit,” and “all territory within said lim¬ its, not being a part of the mainland of the state of Louisiana, became, was, and is a part of the territory of the state of Missis¬ sippi.”
That the acts of 1812, creating the state of Louisiana, failed “to describe the watei line from the most eastern mouth of Pearl river to the Gulf of Mexico,” and hence Louisiana proposed, “without authority in law, to follow the deep-water channel from the mouth of Pearl river to the Gulf of Mexico, — that is, as far south as that point in the sea where the waters of Chandeleur sound merge into the waters of the Gulf of Mexico.”
That the act creating the state of Missis¬ sippi was the organization *of a state gov-
eminent in the western part of Mississippi territory; that the southern part of the ter¬ ritory of Mississippi was added thereto by an act of Congress approved May 14. 1812, which provided: “That all that portion of territory lying east of Pearl river, west of the Perdido, and south of the thirty-first degree of latitude, be, and the same is here¬ by, annexed to the Mississippi territory; to be governed by the laws now in force therein, or which may hereafter be enacted, and the laws and ordinances of the United States, relative thereto, in like manner as if the same had originally formed a part of said territory; and until otherwise provid- ed by law, the inhabitants of the said dis¬ trict, hereby annexed to the Mississippi ter- litory, shall be entitled to one representa¬ tive in the general assembly thereof.” 2 Stat. at L. 734, chap. '84.
that this act and the act admitting the state of Mississippi “recognized the fact that the boundary line of the state of Louis-

17-19
iana embraced no island in the waters to the east of said state and to the south of the Mississippi mainland, or shore, and within 6 leagues of the Mississippi shore; that the said Louisiana acts are not in con¬ flict with the aforesaid Mississippi acts, the boundaries of Louisiana only embracing such islands, as clearly shown by said acts cre¬ ating and admitting her, as were within the Gulf of Mexico and also within 3 leagues of her gulf coast, — that is to say, within the Gulf of Mexico proper and to the south of said state of .Louisiana, as contemplated by Congress; that the said line from the mouth of Pearl river to the Gulf of Mexico, divid¬ ing the territory of Mississippi from the state of Louisiana, was never defined until the passage of the act creating the state of Mississippi, when, for the first time, the southern boundary of the Mississippi ter¬ ritory, the western part of which was, by said act, made the state of Mississippi, was accurately defined and established, as here¬ in stated; that the line above described and defined by the said Mississippi acts includes no islands which are within 3 leagues of the Louisiana mainland and also in the Gulf
of Mexico, as the limits *of the Gulf of Mexico are defined by the said state in her original bill herein.”
That the state of Louisiana “claims title and sovereignty over some of the islands belonging to the state of Mississippi by virtue of certain alleged action of certain officers of the United States government and local officers of the state of Louisiana,” but the claim “is not well founded because of the matters herein set forth, and because said islands and territory have not been sus¬ ceptible to actual use and occupation, and because said claim is in violation of § 3, art. 4, of the Constitution of the United States . . .” But if the court should
adjudge said islands and territory approved by the aforesaid officials to the state of Louisiana to belong to said state, then cross complainant prayed that the claim of title of Louisiana thereto “be restricted to the real lands or islands so lost to the state of Mississippi, and be in no case per¬ mitted to affect any lands under the wa¬ ters, or any of the public oyster reefs there¬ under.”
It was then alleged that Mississippi had “exercised sovereignty and jurisdiction over said waters within 18 miles of her shore aforesaid,” and that by her statutes, as codified in 1857, had asserted such juris¬ diction*
And that, by the legislation of Congress and the state, the “ ‘Mississippi sound’ was recognized as a body of .water, 6 leagues wide, wholly within the state of Mississippi, from Lake Borgne to the Alabama line, sep- 202 U. S.
arate and distinct from ‘the Gulf of Mex¬ ico.’ ”
The cross bill further averred that Con¬ gress, “in the early history of the Republic, in dealing with the Gulf coast or shore,” was not perfectly familiar with the line, and by several acts “creating the Gulf states, respectively, treated the said Gulf coast or shore as a line running generally from east to west,” and said states were, in the con¬ templation of Congress, “so formed and bounded as to give to each state jurisdic¬ tion over the waters adjacent to its shore or coast for a certain specified distance southward from its mainland line; that it was *not intended to give to any state
jurisdiction over waters adjacent to and immediately south and in front of any other state or territory.” But that the deep¬ water channel line contended for by Louis¬ iana would take nearly all of the Han¬ cock county water front, much of that of Harrison county, and possibly some of that of Jackson county, over all which Missis¬ sippi had exercised jurisdiction since her admission.
Reference was then made to the or¬ ganization of Hancock and Jackson coun¬ ties in December, 1812, and of Harrison county, in 1841; and to certain sections of the Revised Code of Mississippi of 1880 and a codification of 1892, making a gen¬ eral reference to islands within 6 leagues of the Mississippi shore; and it was charged that during all this time the government of the Mississippi territory and that of the state of Mississippi had exercised full and complete jurisdiction and sovereignty over the waters in the “Mississippi sound” as a part of the three counties aforesaid.
The prayer was that it be decreed “that the boundary line dividing the states of Mississippi and Louisiana is the line which, beginning at a point 6 leagues due south of that point on the shore where the Ala¬ bama and Mississippi line enters the Gulf of Mexico, runs westwardly with the me- anderings of the shore 6 leagues always therefrom until said line reaches and touch¬ es the real mainland of Louisiana about 2 miles due west of the ‘Indian mound’ and ‘Lake of the Mound,’ and thence in an al¬ most due northward direction along and on the high-tide mark of the said Louis¬ iana mainland to Mississippi sound at or near Nine Mile bayou, and thence further along said mainland at the higli-tide mark westwardly to that point due south cf the middle of the most southern or eastern June tion of Pearl river with Lake Borgne, and thence from said point due north to the said Pearl river; that the said line be lo cated and permanently buoyed at the joint expense of the two states; that the tnl'

title and sovereignty over all the islands and the land under the waters north and east of the said line so established be de-
creed and adjudged to be in the *state of Mississippi, and that the state of Louis¬ iana and her citizens be perpetually en¬ joined from disputing such title and sov¬ ereignty of the state of Mississippi therein,” and for costs and general relief.
The following “Exhibit Map” was at¬ tached. [See post.]
The state of Louisiana filed replication, and also an answer to the cross bill, the allegations of which were in substance de¬ nied.
•
As to the act of May 14, 1812, the state
said that it could not and did not change the boundaries of Louisiana, and that, in fact, the southern portion of the Missis¬ sippi territory as claimed was not then in possession of the United States, and did not extend south of the 31st degree of north latitude; that February 12, 1813, an act was passed “authorizing the President of the United States to take possession of a tract of country lying south of the Mis¬ sissippi territory and west of the river Perdido,” but that this was not published until 1818; nor were the resolution of Jan¬ uary 15 and the act of March 3, 1811, on the relations of the United States to Spain, pub¬ lished until after April 20, 1818. 3 Stat.
at L. 471, 472.
The cause being at issue, much evidence, documentary and otherwise, was taken, and the case was argued October 10, 11, and 12.
Messrs. John Dymond, Jr., F. C. Zach- arie, and Walter Guion argued the cause and filed a brief for complainant:
The mere question of a dispute over the boundaries of states was sufficient to give the court jurisdiction irrespective of the fact as to whether there was any imminent danger of violent or forcible conflict be¬ tween the states, or the citizens thereof.
Rhode Island v. Massachusetts, 12 Pet. 719, 9 L. ed. 1258; Alabama v. Georgia, 23 How. 505, 10 L. ed. 556; Missouri v. Iowa,
7 How. 600, 12 L. ed. 861 ; Florida v. Georgia, 17 How. 478, 15 L. ed. 181 ; Vir¬ ginia v. West Virginia, 11 Wall. .39, 20 L. ed. 67; New Jersey v. New York, 5 Pet. 284, 8 L. ed. 127.
In cases other than those of boundaries this court has taken jurisdiction where the pecuniary interests of states have been in¬ volved.
Pennsylvania v. Wheeling d B. Bridge Go. 13 How. 589, 14 L. ed. 279; South Caro¬ lina v. Georgia, 93 U. S. 4, 23 L. ed. 782.
In other decisions this court has declared that, in order to vest original jurisdiction, a state must have a proprietary interest. 920
Wisconsin v. Pelican Ins. Go. 127 U. S. 287, 32 L. ed. 242, 8 Sup. Ct. Eep. 1370; Louisiana v. Texas, 176 U. S. 1, 22, 44 L. ed. 347, 355, 20 Sup. Ct. Rep. 251.
This bill shows a proprietary interest in the state.
Where there are two conflicting titles, the elder shall be preferred. So where there are conflicting rights as to real ;roperty, courts of equity will inquire not which party was first in possession, but under what instrument he was in possession, and when his right is dated in point of time; or, if there be no instrument, they will ask “When did the right arise? Who had the prior right?”
Broom, Legal Maxims, 7th ed. p. 355.
This principle has been applied by this court in cases of boundaries between states where the grants to the colonies prior to the establishment of our government have seemed to conflict. So in Rhode Island v. Massachusetts, 12 Pet. 658, 9 L. ed. 1234, it is said in the syllabus, “No court acts differently in deciding on boundary between states, than on lines between separate tracts of land,” and that the rules and principles of equity would equally apply between in¬ dividuals.
In Indiana v. Kentucky, 136 U. S. 479, 34 L. ed. 329, 10 Sup. Ct. Rep. 1051, some stress was laid upon the geological char¬ acter of the territory in dispute as com¬ pared with that of the two states, and this geological affinity and similarity was held to be confirmatory of other evidence in the case.
The deep-water sailing channel is the proper boundary line between the two states, recognized by all rules of interna¬ tional law.

Messrs. Walter Guion, John Dymond, Jr., Albert Estopinal, Jr., and Alexander Porter Morse filed a brief for complainant on de¬ murrer :
In a boundary suit between states, a state properly makes its appearance in the Su¬ preme Court of the United States through its governor or chief executive.
The governor, as the special guardian of the state’s interest, is a proper party to initiate necessary litigation. His right to do so is indeed a part of his general pow¬ ers of supervision over the property and welfare of the state ( State ex rel. Mahan v. Dubuclet, 22 La. Ann. 602; State ex rel. Strauss v. Dubuclet, 25 La. Ann. 161), and it therefore is not necessary that he should first be authorized by legislative act.

The allegations of the demurrer to the ef¬ fect that this is not a controversy between two states are negatived by the averments of the bill of complaint ; but if there be any doubt in the mind of this court as to the sufficiency of the allegations of the bill, the case of Kansas v. Colorado, 185 U. S. 125, 46 L. ed. 838, 22 Sup. Ct. Rep. 552, will be sufficient warrant for this court to refuse to dismiss the bill on demurrer.
Messrs. Hannis Taylor and Monroe McClurg argued the cause and filed a brief for defendant:
In cases of doubt or uncertainty, or ap¬ parent conflict or repugnancy, this court will construe all of the acts relating to the same subject-matter together, and in such a manner, if their language will reasonably admit of it, as to permit them all to stand together and remain in full force; if a subsequent act on the same subject affords complete demonstration of the legislative sense of its language, the rule which has been stated, requiring that the subsequent should be incorporated into the foregoing act, is a direction to the courts in expound¬ ing the provisions of the law; if a thing contained in a subsequent statute be within the reason of a former statute, it shall be taken to be within the meaning of that stat¬ ute; and if it can be gathered from a subse¬ quent statute in pari materia what meaning the legislature attached to the words of a former statute, .they will amount to a legis¬ lative declaration of its meaning, and will govern the construction of the first stat¬ ute; acts of Congress dealing with the same subject-matter should be construed not only as expressing the intention of Con¬ gress at the dates the several acts were passed, but the later acts should also be regarded as legislative interpretations of the prior ones ; it is not to be presumed that Congress would grant or even simply release the right of the United States to land con¬ fessedly before granted. This would be only holding out inducements to litigation.

Congress saw fit, in the act admitting Louisiana as a state, to establish for her a land boundary. From the junction of the Rigolets with Lake Borgne to the mouth of the Sabine river the boundary of Louisiana is the “coast;” The vital words of the act are: “Including all islands within 3 leagues of the coast.” Congress thus established a definite land boundary for that state, and not a shadowy and uncertain water bound- ary> as claimed in the bill. A special rule having been thus established by competent authority, a general rule, even if such a one existed, could not be invoked. General rules of international law are never applied un¬ der such circumstances.

The fact that Congress attempted to grant to Mississippi all islands within 18 miles of her coast is conclusive evidence that that body considered the islands in question as such, and that they had not been previously granted to Louisiana. Here the court should apply the rule laid down in Pollard v. Kibbe, 14 Pet. 366, 10 L. ed. 496. It is not to be presumed that Congress would grant or even simply release the right of the United States to land confessedly before granted.
In the construction of statutes, as in the construction of deeds, the cardinal rule is to effectuate, if possible, the entire inten¬ tion of the grantor ; and, in ascertaining that intention, regard must be had to the situation and the relative position of the parties, and the objects which they had in view.
In the construction of statutes one part must be construed by another; to collect the legislative intention the whole must be inspected ( Strode v. Stafford Justices, 1 Brock. 162, Fed. Cas. No. 13,537) ; and re¬ course may be had for this purpose to a proviso which had been repealed by a sub¬ sequent act (Bank for Savings v. The Col¬ lector [Bank for Savings v. Field] 3 Wall. 495, 18 L. ed. 207). Statutes are to be in¬ terpreted so as to give effect to all the words therein, if such interpretation be reasonable, and be neither repugnant to the provisions, nor inconsistent with the objects of the stat¬ ute (United States v. Bassett, 2 Story, 389, Fed. Cas. No. 14,539). It is not to be pre¬ sumed, that the legislature intended that any part of the statute should be without its prope. meaning, force, or effect (Pot¬ ter’s Dwarr. Stat. p. 188, note 8).
Grants made by a legislature are not war¬ ranties; and, if the thing granted was not in the grantor at the time of the grant, no estate passes to the grantee.

The enactment of legislation by a state for the assertion of its sovereignty and ju¬ risdiction, and the taking of judicial ac¬ tion for the same purpose, is such affirma¬ tive action as should be taken to that end.
Mr. James N. Flowers also argued the cause, and, with Messrs. Hannis Taylor, Monroe McClurg, and William Williams, filed a supplemental brief for defendant:
The doctrine of in pari materia is just as applicable in a case of conflict and re¬ pugnancy as it is in a case of doubt and uncertainty.
Statutes are in pari materia which re¬ late to the same person or thing or to the same class of persons or things, and the phrase is applicable to public statutes or general laws made at different times and in reference to the same subject.
26 Am. & Eng. Enc. Law, 2d ed. p. 621.
In great questions which concern the boundaries of states, where great natural boundaries are established in general terms, with a view to public convenience and the avoidance of controversy, we think the great object, where it can be distinctly perceived, ought not to be defeated by those technical perplexities which may sometimes influence contracts between individuals.
In a statute which requires measurement from the coast, the coast is the point of contact of the mainland with the sea; and, when a bay intervenes, the point of contact of the bay with the mainland is to be con¬ sidered coast.

Messrs. William Williams and Monroe McClurg filed a separate brief for defend¬ ant:
The state is not sovereign as to its citi¬ zens or as to another state, and is under no obligation to collect the debts of its cit¬ izens or to otherwise redress their private wrongs. The state cannot loan its name to its citizens or sue in their behalf.

Wisconsin v. Pelican Ins. Co. 127 U. S. 287, 32 L. ed. 242, 8 Sup. Ct. Rep. 1370.
No state can be sued either in its own courts or those of any other state or na¬ tion without its consent, and states can only be sued in proper cases in this court by reason of their agreement in the Consti¬ tution that the judicial power of the Unit¬ ed States shall extend to all cases arising under the Constitution and laws.
The controversies existing at the time of the adoption of the Constitution were the cause and origin of extending the judicial powder of the United States to controversies between the states, and the only purpose of such constitutional provision was to provide a tribunal for settlement of such controver¬ sies as to boundaries and other like con¬ troversies.
It was not the intention of the states, in adopting the Constitution, to give their con¬ sent to be sued whenever a dispute arises between citizens of different states in re¬ gard to commerce or any property right af¬ fecting such citizens.
Mr. Chief Justice Fuller delivered the opinion of the court:
The demurrer was overruled because the court was of opinion that the bill presented a prima facie case of justiciable controversy between the state of Louisiana and the state of Mississippi as to the boundary line between them, and we are clear that the proofs establish the existence of such a con¬ troversy as to fully sustain our jurisdiction.
It is apparent that the enforcement of the oyster legislation of the two states led to a conflict between the authorities of both, which involved a dispute as to the true boundary line.
In 1886 the state of Louisiana passed an act vesting the power to control the oyster industry in the hands of the officials of the parishes of the state in their several locali¬ ties, along general lines laid down in the law. La. Laws 1886, act No. 106. This was followed by the acts of 1892 (No. 110), 1896 (No. 121), and 1900 (No. 159). By the act of 1896 nonresident oyster fisher¬ men were prohibited from fishing oysters in Louisiana waters, and the dredging of oysters was also prohibited, in this particu¬ lar differing from the laws of Mississippi, 024
which permitted it. By a concurrent resolu¬ tion of 1900 a legislative commission was created, to investigate and report on the oyster industry of the state.
In January, 1898, the parochial autho¬ rities of the parish of St. Bernard equipped and sent out an official expedition to exclude from the oyster water of the parish any nonresident *oyster fishermen who might be

found fishing therein. Nonresident Missis¬ sippi oystermen were found fishing oysters there, and they were notified that they must stop fishing and move out of those waters. These Mississippians then complained to the Mississippi authorities and a conference en¬ sued between representatives of the parish of St. Bernard and the county of Hancock.
In January, 1901, at the instance of the Louisiana legislative commission appointed under the act of 1900, and of committees appointed from the police juries of the Lou¬ isiana parishes of St. Bernard and Plaque¬ mines, a meeting of the state officials of Louisiana was held in New Orleans to con¬ sider the subject of the dispute with tho state of Mississippi, and the invasion by nonresidents of the Louisiana oyster waters.
This meeting resulted in the appointment by the governor of Louisiana of a commis¬ sion of five members, and an official com¬ munication from the governor of Louisiana addressed to the governor of Mississippi, requesting the latter to appoint a similar commission to see if it were possible to ef¬ fect an amicable settlement of the dispute between the two states. This Mississippi commission was accordingly appointed, and the two commissions held a joint confer¬ ence in New Orleans in March, 1901. Lou¬ isiana presented at the conference a map showing the Louisiana contention as to the boundary, which is the map attached to the bill, and marked Exhibit E. The Mississippi commission reported that it was impossible to effect an amicable extrajudicial settle¬ ment of the dispute, and that the only hope of settlement was a friendly suit in the Supreme Court of the United States. This report was submitted by the Mississippi commission to the governor of Mis¬ sissippi, and was transmitted to the leg¬ islature of that state. At this session the state of Mississippi passed a new law con¬ trolling her oyster waters and oyster indus¬ try. Laws 1902, chap. 58. This act created a state oyster commission, vested with en¬ tire control of the Mississippi oyster indus¬ try. It took the control of the industry out of the hands of the coast county author¬ ities and centralized it in this state de¬ partment, which was authorized to estab¬ lish a ‘system of patrol of the Mississippi
oyster waters, and to maintain patrol boats to sustain the oyster laws in her territory.

Louisiana v. Mississippi.
35-37
In July, 1902, the state of Louisiana fol¬ lowed the example of the state of Missis¬ sippi and adopted an act (Acts 1902, No. 153) creating a state oyster commission of Louisiana as a state department, vested with full control of the oyster industry of Lou¬ isiana, and authorized to establish patrol boats and maintain an armed patrol on the Louisiana oyster waters to protect her rights in the oyster industry therein. In view of the danger of an armed conflict, the oyster commissions of both states, in September, 1902, adopted a joint resolution establishing a neutral territory between the two states “pending the final decision by the Supreme Court of the United States in the boundary suit to be instituted,” to remain a common fishing ground. This modus vivendi did not include all of the disputed territory, but the waters of Mississippi sound between the deep-water channel and the north shore line of the Louisiana marshes were embraced by it.
In the following October this bill was filed. Louisiana appeared through her gov¬ ernor and her attorney general, and the action of the governor in instituting the suit was subsequently approved, ratified, and confirmed by the legislature.
The facts that the act of Congress admit¬ ting the state of Louisiana gave that state all islands within 3 leagues or 9 miles of her coast, and that the subsequent act of Con¬ gress admitting the state of Mississippi pur¬ ported to give that state all islands within 6 leagues or IS miles of her shore, and that some islands within 9 miles of the Louisi¬ ana coast were also within 18 miles of the Mississippi shore, furnished the basis for a boundary controversy, although, in our judg¬ ment, the apparent inconsistency is recon¬ cilable, as hereinafter explained. And that controversy involved to each state pecuniary values of magnitude, as is shown by the evidence on botii sides. We think that there existed between the two states, in their sov¬ ereign capacity as states, a controversy af¬ fecting the boundary line separating them
in the locality in *question of a clxaracter to justify the exercise of our original juris¬ diction within the rules laid down in Mis¬ souri v. Illinois, 200 U. S. 496, ante, 572, 26 Sup. Ct.

2. The state of Louisiana was admitted

into the Union by the act of Congress ap¬ proved April 8, 1812 (2 Stat. at L. 701, chap. 50). which commenced as follows:
202 U. S. U. S.. Book 50. 5
“Whereas, the representatives of the people of all that part of the territory or country ceded under the name of ‘Louisiana’ by the treaty made at Paris on the thirtieth day of April, one thousand eignt hundred and three, between the United States and France, contained within the following lim¬ its, that is to say: Beginning at the mouth of the River Sabine ; thence by a line to be drawn along the middle of said river, including all islands, to the thir¬ ty-second degree of latitude; thence due north to the northernmost part of the thir¬ ty-third degree of north latitude; thence along the said parallel of latitude to the River Mississippi; thence dow.i the said riv¬ er to the River Iberville; and from thence along the middle of the said river and Lakes Maurepas and Ponehartrain to the Gulf of Mexico; thence bounded bv the said gulf to the place of beginning including all islands within three leagues of the coast;
Map or diagram No. 1, given in the open¬ ing statement, shows the limits as thus de¬ fined.
By an act of Congress approve 1 April 14.
1812 (2 Stat. at L. 708., chap. 57), addi¬ tional territory was added to the state of Louisiana, described thus:
“All that tract of country comprehended within the following bounds, to wit: Be¬ ginning at the junction of the Iberville with the River Mississippi; thence along the middle of the Iberville, the River Amite and of the Lakes Mnurepas and Pontehar- train to the eastern mouth of the Pearl river; thence up the eastern branch of Pearl river to the thirty-first degree of north lat¬ itude ; thence along the said degree of lat¬ itude to the River Mississippi : thence down the said river to the place of beginning, *shall
become and form a part of the said state of Louisiana, and be subject to the Constitu¬ tion and laws thereof in the same manner, and for all intents and purposes, as if it had been included within the original bound¬ aries of the said state.”
This added territory is shown on map or diagram No. 2. The eastern boundary of Louisiana was thereby moved eastward from the Mississippi to Pearl river, and Louisiana was given the country south of the 31st degree of north latitude, and north of the boundary formed by the River Iberville, the middle of Lakes Maurepas and Pontchar- train, and the Rigolets.
The River Iberville is called on this map Bayou Manehac, and is still known by that name. The Rigolets is a gut connecting the waters of Lakes Pontchartrain and Borgne, both of which are bodies of salt water and were originally arms of the sea. In order to reach the open waters of the Gulf of i 925

Mexico from the middle of Lakes Maurepas and Pontehartrain the line ran through the Rigolets into Lake Borgne, and after the addition to the state by the act of April 14, 1812, the eastern boundary line of Lou¬ isiana entered Lake Borgne to the south by Pearl river as well as the Rigolets. To get from Lake Borgne into the open water of the Gulf of Mexico beyond Chandeleur islands and around to the western boundary of Louisiana, it was necessary, as Louisi¬ ana contends, to follow the deep-water chan¬ nel north of Half Moon or Grand island, through Mississippi sound, and thence by the pass between Cat island and Isle ft Pitre, north of the Chandeleur islands, into the open Gulf. Many maps are given in the record, some made at dates long prior to the admission of Louisiana as a state, some at that time, and some within a few years thereafter, and all show the St. Bernard pen¬ insula to be geographically a true part of the state of Louisiana, or of an area of coun¬ try that was to form the state, and that the said peninsula projected itself as a well- defined arm of land out into the waters of the Gulf, branching off as a projection from
the main body of land composing *the state, and forming a part of it. We observe that on many of these early maps the term “peninsula” is applied to this projection, and that designation is sufficiently accurate for the purpose of description.
November 14, 1803, President Jefferson sent a communication to Congress, in which, among other things, he said:
“The object of the following pages is to consolidate the information respecting the present state of Louisiana, furnished to the Executive by several individuals among the best informed on the subject.
“Of the province of Louisiana no general map, sufficiently correct to be depended up¬ on, has been published, nor has any been yet procured from a private source. It is indeed probable that surveys have never been made upon so extensive a scale as to afford the means of laying down the vari¬ ous regions of a country which, in some of its parts, appears to have been but imper¬ fectly explored. . . .
“St. Bernardo.
“On the east side of the Mississippi, about 6 leagues below New Orleans, and at the head of the English bend, is a settlement known by the name of the Poblaeion de St. Bernardo, or the Terre aux Bceufs, extending on both sides of a creek or drain, whose hea,d is contiguous to the Mississippi, and which, flowing eastward, after a course of 18 leagues, and dividing itself into two branches, falls into the sea and Lake Borgne. This settlement consists of two parishes 926
almost all the inhabitants of which are Spaniards from the Canaries, who content themselves with raising fowls, corn, and garden stuff for the market at New Orleans.
The lands cannot be cultivated to any great distance from the banks of the creek, on account of the vicinity of the marsh behind them, but the place is susceptible of great improvement, and of affording another com¬ munication to small craft of from 8 to 10 feet draught, between the sea and the Mis¬ sissippi.”
“Country from Plaquemines to the Sea, and Effect of the Hurricanes.
*“From Plaquemines to the sea is 12 or 13
leagues. The country is low, swampy, chief¬ ly covered with reeds, and having little or no timber, and no settlement whatever. It may be necessary to mention here, that the whole lower part of the country, from the English turn downwards, is subject to over¬ flowing in hurricanes, either by the recoiling of the river, or reflux from the sea on each side; and, on more than one occasion, it has been covered from the depth of 2 to 10 feet, according to the descent of the river, whereby many lives were lost, horses and cattle swept away, and a scene of destruc¬ tion laid. The last calamity of this kind happened in 1794, but fortunately they are not frequent. In the preceding year the engineer who superintended the erection of the fort at Plaquemines was drowned in his house near the fort, and the workmen and garrison escaped only by taking refuge on an elevated spot in the fort, on which there were, notwithstanding, 2 or 3 feet of water. These hurricanes have generally been felt in the month of August. Their greatest fury lasts about twelve hours. They com¬ mence in the southeast, veer about to all the points of the compass, are felt most severely below, and seldom extend more than a few leagues above, New Orleans. In their whole course they are marked with ruin and desolation. Until that of 1793, there had been none felt from the year 1780.”
This communication was, of course, before Congress when the act of 1812, admitting Louisiana, was approved, and the peninsula was clearly recognized as forming part of the parish of St. Bernard, as was its marshy character and that of the adjoining parish.
By the act of Congress, approved March 1,
1817 (3 Stat. at L. 348, chap. 23, § 2), the inhabitants of the western part of the then Mississippi territory were authorized to form for themselves a state constitution and to be admitted into the Union, with the fol¬ lowing boundaries: “Beginning on the riv¬ er Mississippi at the point where the south¬ ern boundary line of the state of Tennessee strikes the same; thence east along the said boundary line to the Tennessee river ; thence

140] up the sa'me to the mouth of Bear ‘creek; thence by a direct line to the northwest cor¬ ner of the county of Washington; thence due south to the Gulf of Mexico: thence westwurdly, including all the islands within six leagues of the shore, to the most eastern junction of Pearl river with Lake Borgne; thence up said river to the thirty-first de¬ gree of north latitude ; thence west along the said degree of latitude to the Mississippi river; thence up the same to the beginning.”
The people in convention, August 15, 1817, formed a constitution and state government (approved subsequently by popular vote), and the state was admitted by resolution December 10, 1817. 3 Stat. at L. 472.
The state of Alabama was admitted by the act of March 2, 1819 (3 Stat. at L. 489, chap. 47, § 2), which provided: ‘‘That the said state shall consist of all the territory included within the following boundaries, to wit: Beginning at the point where the thirty-first degree of north latitude inter¬ sects the Perdido river; thence, east, to the western boundary line of the state of Geor¬ gia ; thence along said line to the southern boundary line of the state of Tennessee; thence, west, along said boundary line, to the Tennessee river; thence, up the same, to the mouth of Bear creek; thence, by a direct ling to the northwest corner of Wash¬ ington county; thence, due south, to the Gulf of Mexico; thence, eastwardly, includ¬ ing all islands within six leagues of the shore, to the Perdido river; and thence, up the same to the beginning.”
The islands, marsh or otherwise claimed by Louisiana in this case were all within 3 leagues of her coast. The act admitting Mississippi was passed five years after the Louisiana act, yet Mississippi claims there¬ under the disputed territory, as being islands within 18 miles of her shore. If it were true that this repugnancy between the two acts existed, it is enough to say that Congress, after the admission of Louisiana, could not take away any portion of that state and give it to the state of Mississippi. The rule, Qui prior est tempore, portior est jure, applied, and § 3 of art. 4 of the Con¬ stitution does not permit the claims of any
(no text on this page in the source reporter)
particular state to be ‘prejudiced by the ex¬ ercise of the power of Congress therein con¬ ferred.
But it is said that the act admitting Lou¬ isiana, the act admitting Mississippi, and the act admitting Alabama, must be con¬ strued as in pari materia ; and, being so construed, that Congress must be held to have had in view in the three acts a division of the coast along the Gulf of Mexico so as to equalize the water frontage of Mississip¬ pi, Louisiana, and Alabama.
We do not regard these acts as in pari 202 U- S-
materia, in any proper sense. They provided for the admission of three separate states, and the subject of each was not only not identical with, but not even similar to, that of the others. They did not form part of a l:c: nogeneous whole, of a common system, so as to allow a claimant under the later act to successfully contend that it changed the earlier act by construction or eiTected such change because declaratory of the meaning of the prior act.
And assuming, for the sake of argument, that the Louisiana and Mississippi acts wore irreconcilably inconsistent, but remember¬ ing that when Louisiana was admitted into the Union, the territory now composing the coast counties of Mississippi, that is, below the 31st degree of north latitude, was not actually a part of the Mississippi territory, but was in dispute between the United States and Spain, the theory of any precon¬ certed design in regard to the water front of the two states is too unreasonable to be entertained.
In the treaty of peace between England, France, and Spain of February 10, 171G, article 7, on the subject of the boundary line separating the dominions of England and France iri the New World, provided: ‘‘That for the future the coniines between the dominions of His Britannic Majesty and those of His Most Christian Majesty in that part of the world shall be fixed irrevocably by a line drawn along the River Mississippi from its source to the River Iberville, and from thence by a line drawn along the mid¬ dle of this river and the Lakes Maurepas and Pontcharfrairi to the sea.” According to this treaty England retained the port of Mobile and its river and everything east itof
the Rigolets. The island of Orleans, formed by the River Iberville, Lakes Maurepas, and Pontchartrain, the Rigolets, the Gulf of Mexico, and the Mississippi river, remained the property of France. In the treaty of February 10. 1703, practically the same lan¬ guage is used in describing the boundary line separating the British from the French ter¬ ritory', and by the. twentieth article the ces¬ sion to England of Florida by Spain and all that Spain possessed on the continent of North America was provided for. By the treaty of September 3, 1783, between Eng¬ land and Spain, England retroceded East and West Florida to Spain. By the treaty of St. lldefonso of October 1, UOu. Spain ceded to France “the colony or prov¬ ince of Louisiana with the . extent that it now has in the hands of Spain, and that it had when France possessed it, and such as it should be after the treaties subsequently entered into between Spain and other states.” April 30, 1803, France ceded to the United States “the colony or province

Oct. Term,
of Louisiana” using the same description as used by Spain in ceding the territory to her, and stating in article 2: “In the cession made by the preceding article are included the adjacent islands belonging to Louisiana ...” [8 Stat. at L. 202.]
There is nothing in any of these transfers to raise a doubt that the peninsula of St. Bernard was part of the Island of Orleans, and that this Island of Orleans was in fact formed by the extension to the sea of the boundary line coming down through the middle of Lakes Maurepas and Pontchar- train, and so finding its way to the sea by the deep-water channel.
March 26, 1804, an act of Congress was approved, dividing the country acquired as Louisiana from France into two parts, pro¬ viding:
“That all that portion of country ceded by France to the United States under the name of Louisiana, which lies south of the Mississippi territory and of an ea<=t and west line to commence on the Mississippi river at the thirty-third degree of north latitude, and to extend V'est to the western boundary of the said cession, shall constitute a ter-
ritory of the United *States under the name of the territory of Orleans, the government whereof shall be organized and administered as follows:
“Section 12. The residue of the province of Louisiana ceded to the United States, shall be called the district of Louisiana, the government whereof shall be organized and administered as follows: . . .” [2 Stat,
at L. 2S3, 287, chap. 38.]
Congress manifestly regarded the lands to the east, that were south of the Mississippi territory, and which form the disputed area of to-day, an part of the original island of Orleans, included in the treaty of April 30, 1803; and these were given to the territory of Orleans, whose southeastern boundary was the original southeastern boundary of the island of Orleans. At that date the Mississippi territory did not extend south of the 31st degree of north latitude, and its domain did not reach the shore of Missis¬ sippi sound, so-called.
February 20, 1811 (2 Stat. at L. 641, chap. 21), an act of Congress was approved “to enable the people of the territory of Or¬ leans to form a constitution and state gov¬ ernment, and for the admission of such state into the Union on an equal footing with the original states and for other purposes.” The description of the limits was as follows: “Beginning at the mouth of the River Sa¬ bine, thence, by a line to be drawn along the middle of the said river, including all islands, to the thirty-second degree of lati¬ tude, thence due north to the northernmost 928
part of the thirty-third degree of north lat¬ itude, thence along the said parallel of lati¬ tude to the River Mississippi, thence down the said river to the River Iberville, and from thence along the middle of the said river and Lakes Maurepas and Ponehartrain to the Gulf of Mexico, thence, bounded by the said gulf to the place of beginning in¬ cluding all islands within three leagues of the coast, etc., etc.”
The eastern boundary thus described is a water boundary, and, in exending this water boundary to the open se;i or Gulf of Mexico, we think it included the Rigolets and the deep-water sailing channel line to get around to the westward. A little *over one year
later Louisiana was created a state by the act of Congress of April 8, 1812, with this identical eastern boundary line; and the ad¬ dition of territory by the act of April 14,
1812, did not affect the deep-water sailing channel line as a boundary.'
April 7, 1798 (1 Stat. at L. 549, chap.
28, § 3), an act was approved “for an Ami¬ cable Settlement of Limits with the State of Georgia, and Authorizing the Establish¬ ment of a Government in the Mississippi Territory,” which read in part: “That all that tract of country bounded on the west by the Mississippi; on the north by a line to be drawn due east from the mouth of the Yasous to the Chatahouchee river; on the east by the River Chatahouchee; and on the south by the 31st degree of north latitude shall be, and hereby is, constituted one dis¬ trict, to be called the Mississippi territory.”
This was in conformity with the treaty be¬ tween Spain and the United States of Oc¬ tober 27, 1795. [8 Stat. at L. 138.] Maps
of that date, and subsequently, show that the admitted rights of the United States did not at the time extend south of the 31st de¬ gree of north latitude at that point.
By an act of January 15, 1811, the Pres¬ ident of the United States was authorized, among other things, in the event that any foreign government attempted to occupy the same, to take possession of the country ly¬ ing east of the River Perdido, and south of the state of Georgia and the Mississippi territory. The River Perdido is in the state of Alabama east of the state of Mississippi, and flows into the Gulf of Mexico between Mobile bay, in Alabama, and Pensacola bay, in 1 lorida. A few days later, and on March 3, 1811, an act of Congress was approved,' providing that the act of January 15, 1811, and this act, should not be published until the end of the next session of Congress, un¬ less with the consent of the President.
By resolution approved January 15, 1811, it was specifically declared that the United States could not, without serious inquietude,

see any part of the territory adjoining the southern border of the United States pass into the hands of any foreign power, “and that a due regard to their own safety com- 1.45] pels *them to provide, under certain contin¬ gencies, for the temporary occupation of the said territory.” 3 Stat. at L. 471.
May 14, 1812, an act of Congress was passed (2 Stat. at L. 734, chap. 84) to en¬ large the boundaries of the Mississippi ter¬ ritory, which used the following language: “That all that portion of territory lying east of Pearl river, west of the Perdido, and south of the thirty-first degree of latitude, be, and the same is hereby, annexed to the Mississippi territory,” etc. The country de¬ scribed was not at the time in the possession of the United States, and on February 12, 1813, Congress passed an act “authorizing the President of the United States to take possession of a tract of country lying south of the Mississippi territory and west of the Eiver Perdido,” which act referred to the tract as “not now in possession of the Unit¬ ed States.” 3 Stat. at L. 472. But it was not until the enabling act in respect of Mis¬ sissippi, approved March 1, 1817, that the language was used: “Thence due south to the Gulf of Mexico ; thence, westwardly in¬ cluding all the islands within six leagues of the shore, to the most eastern junction of Pearl river with Lake Borgne,” etc. [3 Stat. at L. 348, chap. 23, § 2.]
The claim of Mississippi is that the dis¬ puted area is composed of islands, and as those islands are within 18 miles of her shore, that they were given to her by the act of March 1, and the resolution of De- cember 10, 1817. It is true there are some islands in that area, such as Grassy, Half Moon, Petit Pass, and Isle A. Pitre, all of which are between the deep-water channel on the north and the main coast line of St. Bernard peninsula on the south.
The contention of Louisiana is that these islands were previously given to her by the act of April 8, 1812, more than five years prior to the admission of Mississippi, and that her title thereto, eve* if the acts were in conflict, is superior to that of the state of Mississippi; and she also contends that the islands belong to her because they are south of the deep-water sailing channel line, which she submits is the true boundary line between the two states. Mississippi denies
(no text on this page in the source reporter)
that the peninsula *of St. Bernard and the Louisiana marshes constitute a peninsula in the true sense of the word, but insists that they constitute an archipelago of islands. Certainly there are in the body of the Lou¬ isiana marshes or St. Bernard peninsula portions of sea marsh which might tech¬ nically be called islands, because they are land entirely surrounded by water, but they 202 U. S.
are not true islands. They are rather, -as the Commissioner of the General Land Of¬ fice wrote the Mississippi land commission¬ er in 1904, “in fact, hummocks of land sur¬ rounded by the marsh and swamp in said townships. ...”
And when the Louisiana act used the words : “Thence bounded by the said gulf to the place of beginning, including all islands within three leagues of the coast”
[2 Stat. at L. 701, chap. 50], the coast re¬ ferred to is the whole coast of the state, and the peninsula of St. Bernard formed an integral part of it. Lake Borgne and Mis¬ sissippi sound are bodies of salt water, and, as such, parts of the sea or gulf, and as the coast of Louisiana began along the north shore of the peninsula, it is not to be sup¬ posed that the islands referred to by Con¬ gress in the Louisiana act were solely those islands to the south of that state.
The contention of Mississippi is based up¬ on an assumed inconsistency between the Louisiana and the Mississippi acts, but we think, upon a true interpretation, in the light of the facts, that no such inconsistency can be imputed. The maps show that there is a chain, not of alluvial, but of sea-sand islands, running from the west shore of Mo¬ bile bay, in the state of Alabama, westward to and inclusive of Cat island, in the state of Mississippi. This .chain forms the south¬ ern boundary of Mississippi sound, and the islands are all relatively the same distance- from the shore of the states of Mississippi and of Alabama. They, beginning at the eastern end, are Dauphin, Petit Bois, Horn. Ship', and Cat islands, and there are some other islands lying within this chain. If Congress referred to these islands as being thus within 6 leagues of the shore, when the act creating the state of Mississippi was passed, it follows that there would be no conflict with prior existing boundaries of *the state of Louisiana, particularly if the
deep-water sailing channel line be taken as the correct boundary between the states.
And when Congress created a separate ter¬ ritorial government for the eastern part of Mississippi territory and called it Alabama, by the act of March 3, 1817 [3 Stat. at L.
372, chap. 59], it used the same language concerning the western and southern bound¬ ary of the territory: “Thence due south to the Gplf of Mexico, thence eastwardly, in¬ cluding all the islands within six leagues of the shore to the Perdido river and thence up same to the beginning.” It seems ob¬ vious to us that it was to this chain of islands that Congress referred when it ad¬ mitted Mississippi into the Union, and that it had no intention whatsoever of giving Mississippi any claim of ownership in the
929

Oct. Term,
sea-marsh islands, which liad been previously granted to the state of Louisiana.
We are of opinion that the peninsula of St. Bernard in its entirety belongs to Louisi¬ ana ; that the Louisiana marshes at the east¬ ern extremity thereof form part of the coast line of the state; and that the islands within 9 miles of that coast are hers, except as re¬ stricted by the deep-water sailing channel regarded as a boundary. Cat island, for in¬ stance, is within the 9 miles, but it is north of the deep-water channel, is not alluvial, and is conceded by both states to belong to Mississippi.

3. That there is a deep-water sailing chan¬

nel line emerging from the mouth of Pearl river, and extending east between Lower Point Clear and Grand island, is shown by the numerous maps, surveys, and sketches in the record. It separates into two branches, one of them passing between Cat island and Isle h Pitre.
Among the maps put in evidence by Lou¬ isiana is one prepared by George Gauld, M. A., for the British Admiralty, in the year 177S, and, from the relative depths of Avater given, the existence of this same channel, extending out into the Gulf, southwest of Cat island, is shown, and is the same as noted on maps of subsequent years.
February 14, 1839, an act of the legisla-
tureof Mississippi was ^approved, providing for a survey of the Mississippi coast. The survey and report are given in full in the record, and the deep-water channel above re¬ ferred to is traceable in detail on the sketch. The channels indicated on this survey and on the United States Coast and Geodetic Survey map are the same channels. It may be noted, in passing, that the body of water now known as “Mississippi sound,” is not so designated on this sketch, and the first map which uses this name, to which our attention has been called, was issued in 1SGG.
Louisiana lies between the states of Mis¬ sissippi to the east and Texas to the west. The southern portion of Louisiana is geo¬ logically of an alluvial formation, contain¬ ing the delta of the Mississippi river. The peninsula of the parish of St. Bernard is practically a part of this delta formation.
Mississippi’s mainland borders on Missis¬ sippi sound. This is an enclosed arm of the sea, wholly within the United States, and formed by a chain of large islands, ex¬ tending westward from Mobile, Alabama, to Cat inland. The openings from this body of water into the Gulf are neither of them 6 miles wide. Such openings occur between Cat island and Isle it Pitre; between Cat and Ship islands; between Ship and Horn islands; between Horn and Petit Bois is¬ lands; between Petit Bois and Dauphin is¬ lands; between Dauphin island and the 030
mainland on the west coast of Mobile bay.
The maps show all this, and, among others, reference may be made to Jeffrey’s map of 1775, given in the record, and which, in reduced form, is reproduced from Jeffrey’s Atlas of 1800 as the frontispiece of .vol.
2, Adams’s History of the United States.
Now to repeat, the boundary of Louisiana separating her from the state of Mississippi to the east is the thread of the channel of the Mississippi river, and this extends south until it reaches the 31st degree of north lati¬ tude and then runs directly east along that degree until Pearl river is reached; thence south along the channel of that river to Lake Borgne. Pearl river flows into Lake Borgne, Lake Borgne into Mississippi sound, and Mississippi sound into the open Gulf of Mexico * through, among other outlets, South
pass, separating Cat island from Isle a Pitre.
If the doctrine of the thalweg is appli¬ cable, the correct boundary line separating Louisiana from Mississippi in these waters is the deep-water channel.
The term “thalweg” is commonly used by writers on international law in definition of water boundaries between states, meaning, the middle, or deepest, or most navigable channel. And while often styled “fairway” or “midway” or “main channel,” the word itself has been taken over into various lan¬ guages. Thus, in the treaty of Luneville, February 9, 1801, we find “le thalweg de l’Adige,” “le thalweg du Ithin,” and it is similarly used in English treaties and de¬ cisions, and the books of publicists in every tongue.
55, 13 Sup. Ct. Rep. 239, the rule of the thalweg was stated and applied. The con¬ troversy between the states of Iowa and Illinois on the Mississippi river, which flowed between them, was as to the line which separated “the jurisdiction of the two states for the purposes of taxation and other purposes of government.” Iowa con¬ tended that the boundary line was the middle of the main body of the river, with¬ out regard to the “steamboat channel” or deepest part of the stream. Illinois claimed that its jurisdiction extended to the channel upon which commerce on the river by steam¬ boats or other vessels was usually conducted, lliis court held that the true line in a navi¬ gable river between states is the middle of the main channel of the river.
Mr. Justice Field, delivering the opin¬ ion of the court, said:
“When a navigable river constitutes the boundary between two independent states, the line defining the point at which the jurisdiction of the two separates is well

established to be the middle of the main channel of the stream. The interest of each state in the navigation of the river admits of no other line. The preservation by each of its equal right in the navigation of the stream is the subject of paramount interest. It is, therefore, laid down in all the recog- [ 50] nized treatises in international *law of mod¬ ern times that the middle of the channel of the stream marks the true boundary be¬ tween the adjoining states up to which each state will, on its side, exercise jurisdiction. In international law, therefore, and by the usage of European nations, the term ‘middle of the stream,’ as applied to a navigable river, is the same as the middle of the chan¬ nel of such stream, and in that sense the terms are used in the treaty of peace be¬ tween Great Britain, France, and Spain, concluded at Paris in 1763. By the lan¬ guage, ‘a line drawn along the middle of the River Mississippi from its source to the River Iberville,’ as there used, is meant along the middle of the channel of the River Mississippi.”
This judgment related to navigable riv¬ ers. But we are of opinion that, on occa¬ sion, the principle of the thalweg is appli¬ cable, in respect of water boundaries, to sounds, bays, straits, gulfs, estuaries, and other arms of the sea.
As to boundary lakes and landlocked seas, where there is no necessary track of navi¬ gation, the line of demarcation is drawn in the middle, and this is true of narrow straits separating the lands of two different states; but whenever there is a deep-water sailing channel therein, it is thought by the publicists that the rule of the thalweg applies. 1 Martens (F. de) 2d ed. p. 134; Hall, § 38; Bluntschli, 5th ed. §§ 298, 299;
1 Oppenheim, pp. 254, 255.
Thus Martens writes : “What we have said in regard to rivers and lakes is equally applicable to the straits or gulfs of the sea, especially those which do not exceed the or¬ dinary width of rivers or double the dis¬ tance that a cannon can carry.”
So Pradier Foddrd says (vol. 2, p. 202), that as to lakes, “in communication with or connected with the sea, they ought to be considered under the same rule as interna¬ tional rivers.”
The same view is confirmed by decisions of this court and of many arbitral tribu¬ nals.
In Re Devoe Mfg. Go. 108 U. S. 401, 27 L. ed. 764, 2 Sup. Ct. Rep. 894, the ques¬ tion at issue was in regard to the boundary line between New York and New Jersey, un- {51]der an agreement between the two “states. The jurisdiction of the state of New Jersey was claimed “to extend down to the bay of New York, and to the channel midway of 202 U. S.
said bay,” and this court sustained the claim. See Hamburg American 8. S. Go. v. Grube, 196 U. S. 407, 49 L. ed. 529, 25 Sup. Ct. Rep. 352.
In the San Juan water boundary contro¬ versy between the United States and Great Britain, Emperor William I. gave the award in favor of the United States, October 21, 1871, by deciding “that the boundary line between the territory of Her Britannic Ma¬ jesty and the United States should be drawn through the Haro channel;” and it is apparent that the decision was based on the deep-channel theory as applicable to sounds and arms of the sea, such as the straits of San Juan de Fuca; indeed, in a subsequent definition of the boundary, signed by the Secretary of State, the Brit¬ ish Minister, and the British representative, the boundary line was said to be prolonged until “it reaches the center of the fairway of the straits of San Juan de Fuca.” The fairway was the equivalent of the thalweg.
Again, in fixing the boundary line of the Detroit river, under the 6th and 7th articles of the treaty of Ghent, the deep-water chan¬ nel was adopted, giving Belle isle td the United States, as lying north of that chan¬ nel. [8 Stat. at L. 221.]
So in the Alaskan boundary case, the ma¬ jority of the arbitration tribunal, made up of Baron Alverstone, Lord Chief Justice of England, Mr. Secretary Root, and Senators Lodge and Turner, held that the middle of the Portland channel was the proper bound¬ ary line, and included Wales island, to the north of which the channel passed. This sustained the American contention in re¬ gard to the thalweg and the island lying south of it.
But counsel contend that the rule “as to the flow of the midcbannel or thalweg of the River Iberville (now known as Manchae) through the east, through Lakes Maurepas and Pontchartrain, expires by its own limi¬ tation when such midchannel reaches Lake Borgne, which, in contemplation of the rule, is the “open sea, and part of the waters of

the Gulf of Mexico.” This contention is inconsistent, as matter of fact, with the allegation of the cross bill that “the Missis¬ sippi sound was recognized as a body of wa¬ ter 6 leagues wide, wholly within the state of Mississippi, from Lake Borgne to the Alabama line, separate and distinct from the Gulf of Mexico,” and with Mississippi’s Exhibit Map A, presenting her claim, while the record shows that the strip of water, part of Lake Borgne and Mississippi sound, is ‘not an open sea, but a very shallow arm of the sea, having outside of the deep-water channel an inconsiderable depth.
The maritime belt is that part of the sea which, in contradistinction to the open

sea, is under the sway of the riparian states, which can exclusively reserve the fishery within their respective maritime belts for tlieir own citizens, whether fish, or pearls, or amber, or other products of the sea. See Manchester v. Massachusetts, 139 U. S. 240, 35 L. ed. 159, 11 Sup. Ct. Rep. 559; McCready v. Virginia, 94 U. S. 391, 24 L. ed. 248.
In Manchester v. Massachusetts, the court said: “We think it must be regarded as es¬ tablished that, as between nations, the min¬ imum limit of the territorial jurisdiction of a nation over tide waters is a marine league from its coast;' that bays wholly within its territory, not exceeding 2 marine leagues in width at the mouth, are within this lim¬ it; and that included in this territorial jurisdiction is the right of control over fish¬ eries, whether the fish be migratory, free- swimming fish, or free-moving fish, or fish attached to or embedded in the soil. The open sea within this limit is, of course, sub¬ ject to the common right of navigation; and all governments, for the purpose of self¬ protection in time of war or for the pre¬ vention of frauds on its revenue, exercise an authority beyond this limit.”
Questions as to the breadth of the mari¬ time belt or the extent of the sway of the riparian states require no special consider¬ ation here. The facts render such dis¬ cussion unnecessary.
Islands formed by alluvion were held by Lord Stowell, in respect of certain mud is-
lands at the mouth of the Mississippi, *to be “natural appendages of the coast on which they border, and from which, indeed, they are formed.” The Anna (1805) 5 C. Rob.

As to these particular waters, the obser¬ vations of Mr. Hall, 4th ed. p. 129, are in point: “Off the coast of Florida, among the Bahamas, along the shores of Cuba, and in the Pacific, are to be found groups of nu¬ merous islands and islets rising out of vast banks, which are covered with very shoal water, and either form a line more or less parallel with land or compose systems of their own, in both cases inclosing consider¬ able sheets of water, which are sometimes also shoal and sometimes relatively deep. The entrance to these interior bays or la¬ goons may be wide in breadth of surface water, but it is narrow in navigable water.”
He then states the specific case of the Ar¬ chipelago de los Canarios on the coast of Cuba, and says: “In cases of this sort the question whether the interior waters are, or are not, lakes inclosed within the terri¬ tory, must always depend upon the banks, and the width of the entrances. Each must be judged upon its own merits. But in the instance cited, there can be little doubt 032
that the whole Archipelago de los Canarios is a mere salt water lake, and that the boundary of the land of Cuba runs along the exterior edge of the bank/’
In such circumstances as exist in the present case, we perceive no reason for de¬ clining to apply the rule of the thalweg in determining the boundary.

4. Moreover, it appears from the record

that the various departments of the United States government have recognized Louis¬ iana’s ownership of the disputed area; that Louisiana has always asserted it; and that Mississippi has repeatedly recognized it, and not until recently has disputed it.
The question is one of boundary, and this court has many times held that, as between the states of the Union, long ac¬ quiescence in the assertion of a particular boundary and the exercise of dominion and sovereignty over the territory within it should be accepted as conclusive, whatever the international ‘rule might be in respect
of the acquisition by prescription of large tracts of country claimed by both. Vir¬ ginia v. Tennessee, 148 U. S. 503, 37 L. ed.

The Louisiana enabling act of February 20, 1811, provided that all the waste and unappropriated lands in said state should be and remain the property of the United States government. In the disputed area of to-day are included lands and waters lo¬ cated in various townships, all of which are enumerated in the southeastern land dis¬ trict of Louisiana, east of the Mississippi river. The lands in these townships were surveyed by the government about the year 1842, all of them as being in and forming a part of the state of Louisiana. By the swamp land grants of 1849 and 1850, the United States granted to certain states the swamp and overflowed lands within their respective limits, in order that these lands might be reclaimed, protected from over¬ flow, and brought into use. Louisiana made application to the United States for the approval to her of these lands as being part of her territory and situated within her limits. They all lay south of the deep¬ water channel and were all approved to the state of Louisiana May 6, 1852. They were then offered by the state through the regis¬ ter of the state land office for sale, and many sales of them were made from time to time to individuals, and patents issued therefor in various years from 1853 to 1894.

Louisiana v.
the legislature of Louisiana adopted an act which created a Lake Borgne basin levee commission, and provided a board of commis¬ sioners therefor as a department of the state government, and the register of the state land office was authorized to transfer all of the unsold lands to the board, which was done in April, 1895. The board was authorized by law to sell these lands, and al¬ so to levy taxes to be used in establishing a protective levee system in the district. The board made sales of a considerable number
of acres *to different individuals from Sep¬ tember 16, 1898, to March 7, 1902. Isle a Pitre was composed of certain enumerated sections of township 10, south of range 20 east, and these lands were approved to Lou¬ isiana by the Commissioner of the General Land Office of the United States May 6, 1852, as forming part of that state, and they were subsequently patented, sold, and conveyed to various individuals, the chain of title extending from 1852, — a period of over fifty years. The lands forming Isle a Pitre have been paying taxes to the state of Louisiana for years. Political and police control and jurisdiction by the parish of St. Bernard officials were exercised over the disputed area, and many instances are given of police control and jurisdiction by Lou¬ isiana officials over this general territory. This territory consisted, as heretofore stat¬ ed, of what was known as the Louisiana marshes, and it is admitted that they have immemorial ly been known by that name, though some of the witnesses for Missis¬ sippi said that they were also known as Grand marshes; admitting, however, that they were quite as frequently called the Lou¬ isiana marshes.
Some other matters may properly be re¬ ferred to as showing the general under¬ standing of and acquiescence in the bound¬ ary asserted by Louisiana.
In January, 1901, the Superintendent of the Coast and Geodetic Survey was applied to by a member of the house of represen¬ tatives from Mississippi for information in regard to the boundary line between Lou¬ isiana and Mississippi in the present dis¬ puted area, and Hodgkins, an assistant in the department, a well-known expert in such matters, made a report January 30, 1901, which, after considering the subject in all its phases, showed that the correct boundary between the two states in the lo¬ cality is the deep-water sailing channel line contended for by Louisiana.
The United States Geological Survey pub¬ lished in the year 1900 a bulletin devoted to a discussion of the boundaries of the states and territories, and giving a history of changes as they may have occurred. The
third edition was published in *1904. Gan- 802 U. S.

In the opinion of that Bureau, Louisiana was originally bounded by the deep-water channel, and is the owner of the area in dispute to-day, according to the report and the accompanying sketches.
In 1897, Louisiana requested the United States Commission of Fish and Fisheries to make an investigation and report upon certain technical matters in connection with the oyster industry of that state, which in¬ vestigation was made in February, 1898, by the United States Fish Commission steamer Fish Hawk. A map was made of the area investigated in St. Bernard parish, and that map is given in the opening state¬ ment as Diagram No. 4. Louisiana’s own¬ ership was clearly recognized.
The General Land Office of the United States began, as early as 1842, a detailed survey of the land forming the disputed area, of which township plats appear in the record. The survey gave the location of Marsh island, Half Moon or Grand Island, an unnamed island. Petit Pass island, and Isle & Pitre, and the sections and townships comprised in these islands. They were all designated as being in the southeastern land district of Louisiana, east of the Mississippi river.
When, as we have said, Louisiana, in the year 1852, selected these and other lands within her state limits as inuring to her under the swamp land grants, the General Land Office, on May, 6, 1852, recognized the correctness of the claim to the lands and approved and patented them to her as a state. Mississippi also applied for the land inuring to her under the provisions of those grants, and received her swamp lands, but the state never selected and nev¬ er had approved to her, as is shown by the books of the state land office of Mississippi, any of the lands in the disputed area of to¬ day; but it appeared that the state did have in her land office books a record of the lands forming* St. Joseph’s island, which lay immediately north of the deep-water channel, and did not extend south of that channel.
*The General Land Office of the United
States, in all of the maps it has caused to be made of Louisiana and Mississippi, has been consistent in its recognition of the ownership by Louisiana of the disputed area. See maps of Louisiana, 1879, 1886.
1887, 1896; and of Mississippi in 1890.
As before stated, in 1839 an engineer and surveyor made a report and sketch of the coast of Mississippi, under the authority of that state. This showed the territory lying south of the deep-water channel in outline to be a peninsular formation. The

report referred to Horn, Petit Bois, Cat, and Ship islands as belonging to Missis¬ sippi, all of which are east of the disputed territory; and the territory southwest of the deep-water channel, or South pass, was described as the Louisiana marshes. The official maps of Mississippi recognized Lou¬ isiana’s ownership of the disputed territory. The state map of October 26, 1866, which was approved by Governor Humphrey and also by Governor Alcorn, did this; and other maps, as the official map of Missis¬ sippi, published under an act of the legis¬ lature of that state on March 8, 1882; Rand McNally’s sectional map of Missis¬ sippi, compiled from the records of the of¬ fice of the surveyor general of the board of immigration and agriculture, Jackson, Mis¬ sissippi; and the railroad commissioners' map of Mississippi gave like recognition. The only exception seems to be a map of the railroad commission, issued in 1904, two years after this suit was instituted, wherein, on the 18-mile theory, Mississippi for the first time cartographieally extended her claims into the St. Bernard, Louisiana, peninsula.
The record contains much evidence of the exercise by Louisiana of jurisdiction over the territory in dispute, and of the general recognition of it by Mississippi as belonging to Louisiana. Apparently Louisiana had exercised complete dominion over it from 1812 with the acquiescence of Mississippi, unless the fact that the latter made a gen¬ eral reference to islands within 6 leagues of her shore in her Code of 1880 indicated otherwise. But the evidence fails to satisfy us that she attempted any physical posses¬ sion or control until after 1900. The few
instances ‘referred to as showing that Mis¬ sissippi asserted rights in the disputed area are of little weight and require no discus¬ sion.
Our conclusion is that complainant is en¬ titled to the relief sought.
Decree accordingly.
Final decree entered April 23, 1906.
This cause came on to be heard on the pleadings and proofs and was argued by counsel. On consideration thereof it is found by the court that the state of Louis¬ iana, complainant, is entitled to a decree recognizing and declaring the real, certain, and true boundary south of the state of Mississippi and north of the southeast por¬ tion of the state of Louisiana, and sepa¬ rating the two states in the waters of Lake Borgne and Mississippi sound, to be, and that it is, the deep-water channel sailing line emerging from the most eastern mouth of Pearl river into Lake Borgne, and ex¬ tending through the northeast corner of Lake 934

ing the sovereignty and ownership of the state of Louisiana in the land and water territory south and west of said boundary line as laid down on the foregoing map.
And that the costs of this suit be borne by the state of Mississippi.
