Argued Jan. 9, 10, 1934.
Messrs. Duane E. Minard and George S. Hobart, both of Newark, N.J., Walter H. Bacon, and Wm. A. Stevens, of Red Bank, N.J., for the State of New Jersey.
Messrs. Clarence A. Southerland and Reuben Satterthwaite, Jr., both of Wilmington, Del., for the State of Delaware.
Invoking our original jurisdiction, New Jersey brings Delaware into this court and prays for a determination of the boundary in Delaware Bay and river.
The controversy divides itself into two branches, distinct from each other in respect of facts and law. The first branch has to do with the title to the bed or subaqueous soil of the Delaware river within a circle of twelve miles about the town of New Castle. Delaware claims to be the owner of the entire bed of the river within the limits of this circle up to low-water mark on the east or New Jersey side. New Jersey claims to be the owner up to the middle of the channel. The second branch of the controversy has to do with the boundary line between the two states in the river below the circle and in the bay below the river. In that territory as in the river above, New Jersey bounds her title by the Thalweg. Delaware makes the division at the geographical center, an irregular line midway between the banks or shores.
The special master appointed by this court in January, 1930 (280 U.S. 529, 50 S.Ct. 151, 74 L.Ed. 595), has now filed his report. As to the boundary within the circle, his report is in favor of Delaware. To that part of the report exceptions have been filed by New Jersey. As to the boundary in the bay and in the river below the circle, his report is in favor of New Jersey. To that part exceptions have been filed by Delaware. The two branches of the controversy will be separately considered here.
First. The boundary within the circle.
Delaware traces her title to the river bed within the circle through deeds going back two and a half centuries and more.
By force of these acts there was conveyed to the feoffee any title to the river bed within the circle that then belonged to the feoffor. New Jersey insists, however, that the feoffor, the Duke of York, was not then the owner of any territory west of the easterly side of the Delaware river, and hence at the time of the feoffment had no title to convey. Letters patent from Charles II, dated May 12, 1664, had granted to the Duke full title to and government of a large territory in America, embracing much of New England and in particular 'all the land from the west side of Connecticut River to the east side of Delaware Bay,' not including, however, lands or waters to the west. True the Duke had gone into possession of lands westward of the grant, including land within the circle, and through his delegates and deputies was exercising powers of government. His acts in that behalf were the outcome of conflicts with the Dutch. What is now the state of Delaware had been subject to the government of the Dutch until 1664, when with the victory of the English arms it became an English colony. From that time until August 24, 1682, the date of the deed of feoffment, Delaware was governed (with the exception of a brief period from July, 1763, to February 9, 1764) as a dependency of the Government and Colony of New York through governors commissioned by the Duke of York and Albany. Upon the delivery of the deed to Penn, the Duke was the de facto overlord of the land within the circle, though title at that time was still vested in the Crown.
The deed of feoffment had in it a covenant for further assurance at any time within seven years. At the instance of Penn and with little delay, the feoffor took steps to carry out this covenant and thus rectify his title. On March 22, 1682/3, letters patent under the Great Seal of England were issued to the Duke of York for the identical lands and waters described in the deed of feoffment from York to William Penn.1 There is no doubt that these letters were delivered to the Duke. The special master has found upon evidence supporting the conclusion that they were afterwards delivered to Penn from whom they passed to his descendants. The master also found, and again upon sufficient evidence, that the letters patent so delivered 'were never thereafter surrendered, nor was the grant of lands and waters thereby made ever abandoned nor was its validity ever impaired by any act or proceeding.' By force of this grant there passed to the Duke of York a title to the land within the circle which inured by estoppel to the grantee under the feoffment.
The applicable principle in such circumstances is among the rudiments of the law of property. The covenant generating the estoppel is commonly one of warranty or seisin. Irvine v. Irvine, 9 Wall. 617, 19 L.Ed. 800; Van Rensselaer v. Kearney, 11 How. 297, 323, 325, 13 L.Ed. 703; Tefft v. Munson, 57 N.Y. 97; Vanderheyden v. Crandall, 2 Denio (N.Y.) 9, affirmed Wendell v. Crandall, 1 N.Y. 491; White v. Patten, 24 Pick.(Mass.) 324.2 The effect is the same where the covenant is one for further assurance. Taylor v. Debar, 1 Chan.Cas. 274 (1676); Lamb v. Carter, 14 Fed. Cas. page 991, No. 8,013, 1 Sawy. 212; Wholey v. Cavanaugh, 88 Cal. 132, 25 P. 1112; Hope v. Stone, 10 Minn. 141 (Gil. 114); Norfleet v. Russell, 64 Mo. 176. To enforce that conclusion we do not need to wander far afield and consider other deeds than the specific one in question. There exists for our enlightenment the opinion of the chancellor in an historic litigation where the relation between the feoffment of August, 1682, and the later patent from the Crown, was the very point at issue. A dispute had arisen between Lord Baltimore and Penn as to the title to part of the Delaware territory. On May 10, 1732, after Penn was in his grave, there was an agreement between his sons and Baltimore for the settlement of the boundaries between Pennsylvania, Delaware, and Maryland. Three years later a bill was filed in chancery for the specific performance of the agreement of May, 1732, to which suit the Attorney General was made a party as the representative of the Crown.3 The Duke of York had become King under the name of James II on February 6, 1685, and George II sat upon the throne when the cause in chancery was heard. The Lord Chancellor, Hardwicke, gave judgment for the Penns. Penn v. Lord Baltimore, 1 Ves Sen. 444; also Ridg. t H. 332. In his opinion he holds that the effect of the letters patent is to make the deed of feoffment good either by force of an estoppel or by converting the feoffor into a trustee for the feoffee. The objection is urged upon him that an estoppel will not prevail against the Crown. The chancellor makes it plain that he is not favorably impressed. 'For the Duke of York, being then (i.e., at the date of the feoffment) in nature of a common person, was in a condition to be estopped by a proper instrument.' At the same time, he is diffident about declaring a technical estoppel, nor is there need to go so far. If his Majesty was not estopped, he was in any event a trustee of the title for the use of the feoffee, which will bring about a like result. 'The Duke of York * * * while a subject was to be considered as a trustee; why not afterwards as a royal trustee?' 'His successors take the legal estate under the same equity; and it is sufficient for plaintiffs if they have an equitable estate.' So Lord Baltimore must make performance in accordance with the contract. True, the decree for performance will be 'without prejudice to any prerogative, right, or interest in the Crown.' This again is by virtue of the deference owing to the Crown by the keeper of his conscience. 'Being liberated from the restraints of the lord chancellor, we are at liberty to say, that the duke, at the date of the deeds, being a subject, was, in this respect, only 'a common person,' and as much bound by estoppel as any other subject.' Per Sergeant, Arbitrator, in the case of Pea Patch Island, 30 Fed. Cas. pages 1123, 1151, No. 18,311.
In the meantime Penn had proceeded to organize a government for the Delaware territory. On October 29, 1682, he issued a summons to persons of note in the community to meet him at the town of New Castle on November 2 for the holding of a General Court to settle the jurisdiction of the territory. At that court he announced his title derived from the Duke of York, and instructed the magistrates that until laws were enacted by a proper assembly they should take for their guide the laws that had been provided by his Royal Highness for the Province of New York, promising that they should be governed thereafter by such laws and orders as they should consent to by their own deputies and representatives. A general assembly having been summoned, an Act of Union was passed, December 7, 1682, whereby the three counties of Delaware territory were annexed to Pennsylvania. In the same month was enacted an Act of Settlement providing for a Provincial Council and Assembly and reciting the letters patent to Pennsylvania and the deeds of release and feoffment from the Duke of York. Following the establishment of this government, Penn and his successors as Proprietaries and Governors, and the Assembly and Council of the Province, together with the Assembly of the Lower Counties subsequently established, continued to exercise the power of government in all its plenitude over Pennsylvania and the Delaware territory. This continued until the Revolution except for a brief interruption during the reign of William and Mary.
There were, it is true, intermittent challenges both of the proprietary interest of Penn and his successors and of their governmental powers. As to these last, the most serious challenge was one that followed the accession of William and Mary in February, 1689, after the deposition of James II as the result of the 'Glorious Revolution.' Penn, who had been a favorite of royalty during the reign of James, was for a time under a cloud. In 1692, he was removed from the Government of Pennsylvania, including the New Castle country, and his place given to a successor. But he was soon restored to power, and, it seems, to the royal confidence. In August, 1694, there was an Order in Council by which he was reestablished in his former office. In the same month letters patent issued under the Great Seal of State restoring him in the most formal way to the administration of the government of the 'said province and territories,' and revoking any other appointment inconsistent therewith.
This patent, it would seem, had settled for all time the validity of his exercise of governmental powers, however much it may have left in doubt his title to the land. Mutterings of uncertainty, however, continued to be heard as to his rights and powers in both aspects. In 1701, he had correspondence with the Board of Trade which showed itself restless on the subject of his ownership. At intervals during the reign of Anne and afterwards he was required to sign a declaration that the approval by the Crown of his governmental acts, such as the appointment of a deputy, was not to be construed in any manner to diminish 'her Majesty's claim of right to the said three lower counties.' But the claims of right thus reserved were never admitted by Penn to be valid, nor were they ever pressed by the Crown. Not even the petitions of jealous rivals, egging the Crown on, were of avail to wake it into action. Thus, in 1717, the Earl of Sutherland applied for a grant of the three Lower Counties, asserting that he was ready to prove that the title was in the Crown. The Attorney General issued a summons to Penn to be present at a hearing, but Penn, who had suffered a stroke of apoplexy, was unable to appear, and the proceeding was allowed to lapse. A like fate awaited similar petitions submitted in later years. Reservations of the royal claims might continue to be made by cautious scriveners. By the time of the Revolution they were little more than pious formulas. A title, good of record when reinforced by the patent of 1683, had been confirmed by a century of undisturbed possession. When the Treaty of Paris was signed in 1783, the land within the circle was part of the territory of Delaware, and the title was in the Penns or in persons claiming under them.
We do not yield assent to the contention that the effect of these acts was to establish a new boundary between Delaware and New Jersey either as the result of estoppel or through practical construction. There is no element of estoppel. The declarations in respect of title were not addressed to New Jersey, nor did action follow on the faith of them. There is not even a suficient basis for a claim of practical construction. The declarations were framed alio intuitu, with an eye to private titles, not to public boundaries. In the economic unrest and disturbance of the day, the inhabitants of Delaware were ready to disavow the claims of the Penns and others to the ownership of vast areas of uncultivated land. This is far from meaning that there was a disavowal of the grants whereby the colony of Delaware had derived its form and being. What the legislation had in view was enlargement, not restriction, of the domain of common ownership. The truth, indeed, is that for the purpose of an inquiry into the boundaries between colonies or states, questions of private ownership are of secondary importance. The Penns' title may have been misjudged, or may even have failed for reasons not now apparent, and yet it does not follow that the boundaries of New Jersey had thereby been enlarged or those of Delaware curtailed. Such a result could not be wrought without successfully impeaching the letters patent of 1683 whereby a seigniory in the new world was conveyed by Charles to James. The effect of those letters was to define the territorial limits of the province or colony of Delaware, whether Penn and his successors took anything thereby or not. The colony of Delaware as defined by this patent was the one that declared its independence in 1776 and that succeeded in 1783 to any fragment of ownership abiding in the Crown. In resuming the title to uncultivated lands, its people had no thought of modifying the ancient boundaries, of relinquishing a foot of soil above the waters or below. The later history of the controversy between the states makes this abundantly clear, if it could otherwise be doubtful. What concerns us now is more than a question of meum and tuum between one man and another. One concern is with the meaning of an instrument of government, a patent of jurisdiction, which was to generate a state.
The letters patent of March 1683, being basic to the defendant's title, there must be another word of reference to the contention for the complainant that the letters were surrendered in April, 1683, a month after they were granted. The special master, as we have already stated, has made a finding to the contrary, and has summarized the evidence. There would be no profit now in repeating the analysis. Not only does the master find that there was no surrender of the patent, he finds that the original patent is in evidence before him. His holding that there was no surrender is in line with Lord Hardwicke's judgment in Penn v. Lord Baltimore. His holding that the original letters are extant and in the custody of Delaware is in line with the judgment of the arbitrator, rendered eighty-five years ago, in the case of Pea Patch Island, supra. We see no adequate reason for rejecting his conclusion.
Assuming the existence of the patent, New Jersey makes the claim that in its application to the river bed it is void upon its face in that the Crown was without power to grant away the soil beneath navigable waters. The objection will not hold. The letters patent to the Duke of York and the grant from York to Penn were not for private uses solely, but for purposes of government. There is high authority for the view that power was in the Crown by virtue of the jus privatum to convey the soil beneath the waters for uses merely private, but subject always to the jus publicum, the right to navigate and fish. Commonwealth v. Alger, 7 Cush. (Mass.) 53; People v. N.Y. & S.I. Ferry Co., 68 N.Y. 71. 76; People v. Steeplechase Park Co., 218 N.Y. 459, 473, 113 N.E. 521, Ann. Cas. 1918B, 1099; Shively v. Bowlby, 152 U.S. 1, 13, 14 S.Ct. 548, 38 L.Ed. 331; Hale, De Jure Maris, p. 22. Never has it been doubted that the grant will be upheld where the soil has been conveyed as an incident to the grant or delegation of powers strictly governmental. Martin v. Waddell, 16 Pet. 367, 410, 413, 10 L.Ed. 997, Massachusetts v. New York, 271 U.S. 65, 89, 90, 46 S.Ct. 357, 70 L.Ed. 838. In such circumstances, 'the lands under the navigable waters passed to the grantee, as one of the royalties incident to the powers of government; and were to be held by him, in the same manner, and for the same purposes, that the navigable waters of England, and the soils under them, are held by the Crown.' Martin v. Waddell, supra, page 413 of 16 Pet., 10 L.Ed. 997. The grant from Charles II to York was upon its face an instrument of government. The feoffments from York to Penn were in furtherance of kindred ends. Penn had no thought of using his title to the soil as an obstruction to navigation or to any other common right. In a letter to one of his commissioners he writes as early as April, 1683, concerning boundary negotiations with the Province of New Jersey: 'Insist upon my Title to ye River, Soyl and Islands thereof according to Grant. * * * Whatever bee ye Argument, they are bounded Westward by the River Delaware, yn they cannot go beyond low water mark for land. They have ye Liberty of ye River, but not ye Propriety.' The title to the soil, which was subject to the jus publicum while it was vested in the King and his grantees, is subject to the same restrictions in the ownership of Delaware. The patent and the deeds under it are not void for want of power.
Delaware's chain of title has now been followed from the feoffment of 1682 to the early days of statehood, and has been found to be unbroken. The question remains whether some other and better chain can be brought forward by New Jersey. Unless this can be done, Delaware must prevail. But down to the Peace of 1783 at the end of the Revolution, New Jersey has no chain to offer. Up to that time, if not afterwards, her reliance is less upon the strength of her own title than on the weakness of her adversary's. The supposed defects have already been reviewed in this opinion, and have been found to be unreal. There is still to be considered whether events during the years of statehood have worked a change of ownership. New Jersey argues that they have, though not even during those years does she build her claim of title upon instruments of record. Her claim is rather this, that through the exercise of dominion by riparian proprietors and by the officers of government, title to the subaqueous soil up to the centre of the channel has been developed by prescription. The special master held otherwise, and we are in accord with his conclusion.
The acts of dominion by riparian proprietors are connected with the building of wharves and piers that project into the stream. The structures were built and maintained without protest on the part of Delaware, and no doubt with her approval. There is nothing in their presence to indicate an abandonment by the Sovereign of title to the soil. By the law of waters of many of our states, a law which in that respect has departed from the common law of England, riparian proprietors have very commonly enjoyed the privilege of gaining access to a stream by building wharves and piers, and this though the title to the foreshore or the bed may have been vested in the state. Yates v. Milwaukee, 10 Wall. 497, 19 L.Ed. 984; Scranton v. Wheeler, 179 U.S. 141, 157, 158, 21 S.Ct. 48, 45 L.Ed. 126; Shively v. Bowlby, supra, at pages 24, 55 of 152 U.S., 14 S.Ct. 548; Town of Brookhaven v. Smith, 188 N.Y. 74, 80 N.E. 665, 9 L.R.A. (N.S.) 326; United States v. Dern, 289 U.S. 352, 357, 53 S.Ct. 614, 77 L.Ed. 1250. New Jersey in particular has been liberal in according such a license (State v. Jersey City, 25 N.J. Law, 525), and so, it seems, has Delaware (Harlan & Hollingsworth Co. v. Paschall, 5 Del.Ch. 435; State v. Reybold, 5 Har. 484, 486), though in Delaware, unlike New Jersey, title to the foreshore is in the riparian proprietor. From acquiescence in these improvements of the river front, there can be no legitimate inference that Delaware made over to New Jersey the title to the stream up to the middle of the channel or even the soil under the piers. The privilege or license was accorded to the owners individually and even as to them was bounded by the lines of their possession.
The truth indeed is that almost from the beginning of statehood Delaware and New Jersey have been engaged in a dispute as to the boundary between them. There is no room in such circumstances for the application of the principle tht long acquiescence may establish a boundary otherwise uncertain. Vermont v. New Hampshire, 289 U.S. 593, 613, 53 S.Ct. 708, 77 L.Ed. 1392; Indiana v. Kentucky, 136 U.S. 479, 509, 511, 10 S.Ct. 1051, 34 L.Ed. 329; Massachusetts v. New York, supra, page 95 of 271 U.S., 46 S.Ct. 357. Acquiescence is not compatible with a century of conflict. Only a few instances will be mentioned among many that are available. In 1813, the Delaware Assembly ceded to the United States an island in the Delaware river, east of the main channel and within the twelve mile circle, for the erection of a fort. A controversy arose between the United States as holder of the Delaware title and Henry Gale who claimed under New Jersey. In 1836, Gale brought ejectment in the United States Circuit Court against Beling, a tenant. Mr. Justice Baldwin charged the jury that Penn had no title, but the charge makes it plain that he had no knowledge of the letters patent of 1683, and that they were not in evidence before him. Later an arbitration was agreed upon between Humphrey, who had succeeded to the New Jersey title, and the Government of the United States, represented by the Secretary of War. In that proceeding the award was in favor of the Government. The opinion by the arbitrator, which was announced in January, 1849, is a careful and able statement of the conflicting claims of right. See the case of Pea Patch Island, supra. But the controversy would not down. In 1877, New Jersey began a suit in this court to establish the disputed boundary. It slumbered for many years, and finally in April, 1907, was discontinued without prejudice. 205 U.S. 550, 27 S.Ct. 793, 51 L.Ed. 925. If a record such as this makes out a title by acquiescence, one is somewhat at a loss to know how protest would be shown.
This opinion, though it has summarized many facts and arguments, has perforce omitted many others, important in the view of counsel. We content ourselves with the statement that they have not been overlooked. Omission is the less serious in view of the able and comprehensive report submitted by the special master. All that matters most in this keen but amicable controversy is there set forth at large, and there and in the supporting documents the student of our local history can live it over when he will.
We uphold the title of Delaware to the land within the circle.
Second. The boundary below the circle in the lower river and the bay.
Below the twelve-mile circle there is a stretch of water about five miles long, not different in its physical characteristics from the river above, and below this is another stretch of water forty-five miles long where the river broadens into a bay.
The title to the soil of the lower river and the bay is unaffected by any grant to the Duke of York or others. The letters patent to James do not affect the ownership of the bed below the circle. Up to the time when New Jersey and Delaware became independent states, the title to the soil under the waters below the circle was still in the Crown of England. When independence was achieved, the precepts to be obeyed in the division of the waters were those of international law. Handly's Lessee v. Anthony, 5 Wheat. 374, 379, 5 L.Ed. 113.
International law today divides the river boundaries between states by the middle of the main channel, when there is one, and not by the geographical center, halfway between the banks. Iowa v. Illinois, 147 U.S. 1, 7, 8, 9, 13 S.Ct. 239, 37 L.Ed. 55; Keokuk & Hamilton Bridge Co. v. Illinois, 175 U.S. 626, 631, 20 S.Ct. 205, 44 L.Ed. 299; Louisiana v. Mississippi, 202 U.S. 1, 49, 26 S.Ct. 408, 571, 50 L.Ed. 913; Arkansas v. Tennessee, 246 U.S. 158, 169, 170, 38 S.Ct. 301, 62 L.Ed. 638, L.R.A. 1918D, 258; Arkansas v. Mississippi, 250 U.S. 39, 39 S.Ct. 422, 63 L.Ed. 832; Minnesota v. Wisconsin, 252 U.S. 273, 282, 40 S.Ct. 313, 64 L.Ed. 558. It applies the same doctrine, now known as the doctrine of the 'Thalweg,' to estuaries and bays in which the dominant sailing channel can be followed to the sea. Louisiana v. Mississippi, supra; and compare 1 Halleck International Law (4th Ed.) p. 182; Moore, Digest International Law, vol. 1, p. 617; Matter of Devoe Manufacturing Co., 108 U.S. 401, 2 S.Ct. 894, 27 L.Ed. 764; The Fame, 8 Fed. Cas. page 984, No. 4,634, Story, J.; The Open Boat, 18 Fed. Cas. page 751, No. 10,548, Ware, J. The 'Thalweg,' or downway, is the track taken by boats in their course down the stream, which is that of the strongest current. 1 Westlake, International Law, p. 144; Orban, Etude de Droit Fluvial International, pp. 343, 343; Kaeckenbeck, International Rivers, p. 176; Hyde, supra; Fiore, Internalational Law Codified, § 1051; Calvo, Dictionnaire de Droit International. Delaware makes no denial that this is the decisive test whenever the physical conditions define the track of navigation. Her position comes to this, that the bay is equally navigable in all directions, or at all events was no navigable in 1783, and that in the absence of a track of navigation the geographical center becomes the boundary, not of choice, but of necessity. As to the section of the river between the bay and the circle, the same boundary is to be accepted, we are told, as a matter of convenience.
The underlying rationale of the doctrine of the Thalweg is one of equality and justice. 'A river,' in the words of Holmes, J. (New Jersey v. New York, 283 U.S. 336, 342, 51 S.Ct. 478, 479, 75 L.Ed. 1104), 'is more than an amenity, it is a treasure.' If the dividing line were to be placed in the centre of the stream rather than in the centre of the channel, the whole track of navigation might be thrown within the territory of one state to the exclusion of the other. Considerations such as these have less importance for commonwealths or states united under a general government than for states wholly independent. Per Field, J., in Iowa v. Illinois, supra, page 10 of 147 U.S., 13 S.Ct. 239. None the less, the same test will be applied in the absence of usage or convention pointing to another. Iowa v. Illinois, supra. Indeed, in 1783, the equal opportunity for use that was derived from equal ownership may have had a practical importance for the newly liberated colonies, still loosely knit together, such as it would not have today. They were not taking any chances in affairs of vital moment. Bays and rivers are more than geometrical divisions. They are the arteries of trade and travel.
The commentators tell us of times when the doctrine of the Thalweg was still unknown or undeveloped. Anciently, we are informed, there was a principle of co-dominion by which boundary streams to their entire width were held in common ownership by the proprietors on either side. 1 Hyde, International Law, p. 243, § 137. Then, with Grotius an Vattel, came the notion of equality of division (Nys, Droit International, vol. 1, pp. 425, 426; Hyde, supra, p. 244, citing Grotius, De Jure Belli et Pacis, and Vattel, Law of Nations), though how this was to be attained was still indefinite and uncertain, as the citations from Grotius and Vattel show.5 Finally, about the end of the eighteenth century, the formula acquired precision, the middle of the 'stream' becoming the middle of the 'channel.' There are statements by the commentators that the term Thalweg is to be traced to the Congress of Rastadt in 1797 (Engelhardt, Du Re gime Conventionnel des Fleuves Internationaux, p. 72; Koch, Histoire des Traite § de Paix, vol. 5, p. 156), and the Treaty of Lune ville in 1801. Hyde, supra, pp. 245, 246; Kaeckenbeck, International Rivers, p. 176; Adami, National Frontiers, translated by Behrens, p. 17. If the term was then new, the notion of equality was not. There are treaties before the Peace of Lune ville in which the boundary is described as the middle of the channel, though, it seems, without thought that in this there was an innovation, or that the meaning would have been different if the boundary had been declared to follow the middle of the stream. Hyde, supra, p. 246. Thus, in the Treaty of October 27, 1795, between the United States and Spain (Article IV), it is 'agreed that the western boundary of the United States which separates them from the Spanish colony of Louisiana is in the middle of the channel or bed of the River Mississippi.' Miller, Treaties and other International Acts of the United States of America, vol. 2, p. 321.6 There are other treaties of the same period in which the boundary is described as the middle of the river without further definition, yet this court has held that the phrase was intended to be equivalent to the middle of the channel. Iowa v. Illinois, Arkansas v. Tennessee, Arkansas v. Mississippi, supra. See, e.g., the Treaty of 1763 between Great Britain, France and Spain, which calls for 'a line drawn along the middle of the River Mississippi.' The truth plainly is that a rule was in the making which was to give fixity and precision to what had been indefinite and fluid. There was still a margin of uncertainty within which conflicting methods of division were contending for the mastery. Conceivably that is true today in unusual situations of avulsion or erosion. Hyde, supra, pp. 246, 247. Even so, there has emerged out of the flux of an era of transition a working principle of division adapted to the needs of the international community. Through varying modes of speech the law has been groping for a formula that will achieve equality in substance, and not equality in name only. Unless prescription or convention has intrenched another rule (1 Westlake, International Law, p. 146), we are to utilize the formula that will make equality prevail.
It is thus with the formula of the Thalweg in its application to the division between Delaware and New Jersey. We apply it to that boundary, which goes back to the Peace of Paris, just as we applied it to the boundary between Illinois and Iowa, which derives from a treaty of 1763 (Iowa v. Illinois, Keokuk & Hamilton Bridge Co. v. Illinois, Arkansas v. Tennessee, Arkansas v. Mississippi, supra), or to that between Louisiana and Mississippi (202 U.S. 1, 16, 26 S.Ct. 408, 571, 50 L.Ed. 913), which goes back to 1812, or between Minnesota and Wisconsin (252 U.S. 273, 40 S.Ct. 313, 64 L.Ed. 558), going back to 1846. Indeed, counsel for Delaware make no point that the result is to be affected by difference of time. In requests submitted to the master they have asked for a finding that 'there was in 1783 no well defined channel in the Delaware Bay constituting a necessary track of navigation and the boundary line between the States of Delaware and New Jersey in said bay is the geographical center thereof.' The second branch of the request is dependent on the first. This is clear enough upon its face, but is made doubly clear by the exceptions to the report and by the written and oral arguments. The line of division is to be the center of the main channel unless the physical conditions are of such a nature that a channel is unknown.
We have seen that even in the bay the physical conditions are consistent with a track of navigation, which is also the course of safety. Counsel do not argue that such a track is unknown in the five miles of river between the bay and the circle. The argument is, however, that the geographical center is to be made the boundary in the river as a matter of convenience, since otherwise there will be need for a sharp and sudden turn when the river meets the bay. Inconvenient such a boundary would unquestionably be, but the inconvenience is a reason for following the Thalweg consistently through the river and the bay alike instead of abandoning it along a course where it can be followed without trouble. If the boundary be taken to be the geographical center, the result will be a crooked line, conforming to the indentations and windings of the coast, but without relation to the needs of shipping. Minnesota v. Wisconsin, supra. If the boundary be taken to be the Thalweg, it will follow the course furrowed by the vessels of the world.
The report will be confirmed, and a decree entered accordingly, which, unless agreed to by the parties, may be settled upon notice.
Within the twelve-mile circle, the river and the subaqueous soil thereof up to low water mark on the easterly or New Jersey side will be adjudged to belong to the state of Delaware, subject to the Compact of 1905.
Below the twelve-mile circle, the true boundary between the complainant and the defendant will be adjudged to be the middle of the main ship channel in Delaware river and bay.
The following is the description: 'All that the Towne of Newcastle otherwise called Delaware and the fort therein or thereunto belonging scituate lying and being between Maryland and New Jersey in America And all that Tract of land lying within the Compasse or Circle of twelve miles about the said Towne Scituate lying and being upon the River of Delaware and all Islands in the said River of Delaware and the said River and Soyle thereof lying North of the Southermost part of the said Circle of twelve miles about the said Towne And all that Tract of Land upon Delaware River and Bay beginning twelve miles South from the said Towne of Newcastle otherwise called Delaware and extending South to Cape Lopen.' Powers of government and other proprietary and seignorial rights were granted to the Duke along with ownership of the fee.
Compare, however, as to covenants of seisin, Doane v. Willcutt, 5 Gray (Mass.) 328, 66 Am.Dec. 369; Allen v. Sayward, 5 Me. (5 Greenl.) 227, 17 Am.Dec. 221.
The complainant points for illustration to the construction of important works for the use of the Dupont Co. 4,400 feet below low water level, and taxation of these works like other property in New Jersey. At that time controversy was flagrant between the two states. No inference of ownership can be drawn from dominion exerted in such conditions.

Nys traces the concept of the Thalweg to a period earlier than the Treaty of Munster, 1648. Droit International, v. 1, p. 426.
'International law, as well as domestic law, may not contain, and generally does not contain, express rules decisive of particular cases; but the function of jurisprudence is to resolve the conflict of opposing rights and interests by applying, in default of any specific provision of law, the corollaries of general principles. * * * This is the method of jurisprudence; it is the method by which law has been gradually evolved in every country resulting in the definition and settlement of legal relations as well between States as between private individuals.' The case of the Eastern Extension Australasia and China Telegraph Co., Ltd., decided November 9, 1923, by the British American Arbitral Tribunal under the Convention of August 18, 1910, Nielsen's Report, pp. 75, 76, quoted by Lauterpacht, supra, p. 110.
