Philadelphia Co. v. Stimson

delivered the opinion of the court.

This suit was brought in the Supreme Court of the-District of Columbia to set aside certain harbor lines in the harbor of Pittsburgh, Pennsylvania, so far as they encroached upon land owned by the complainant, and to restrain the Secretary of War from causing criminal proceedings to be instituted against the complainant because of the reclamation and occupation, of its. land outside the prescribed limits. The Court of Appeals of the District affirmed a decree sustaining a demurrer to the bill, and the complainant appeals.

The allegations of the bill, in substance, are as follows:

The complainant, a corporation of the Commonwealth of Pennsylvania, is the owner in-fee of “Brunot’s Island,” formerly Chartier’s .or Hamilton’s Island, in the .Ohio River, in Allegheny County, Pennsylvania. In 1858, a statute was enacted in Pennsylvania providing .for the appointment of commissioners to ascertain and mark the *614 lines of ordinary high and low water in the Allegheny, Monongahela and Ohio rivers in the vicinity of Pittsburgh. The act recited that the lines of land along the shores of the rivers had not been clearly ascertained, and it was important to all persons interested that their several rights and privileges should be defined. After the Commissioners’ surveys had been completed and the lines located, opportunity was to be afforded in the court, by which they were appointed, for any needed corrections; and the map or plan finally determined upon was to be recorded. The statute declared that “the lines so approved shall forever after be deemed, adjudged and taken firm and stable for the purposes aforesaid.” Proceedings were had accordingly and the high and low-water lines along the shore of Brunot’s Island were definitely fixed. In consequence the bill asserts that all the land, whether or not under water, inside of the Commissioners’ lines became the property of the owners of Brunot’s Island; and that by virtue of the statute, and the action of the Commissioners under it in fixing the high-water line as a permanent boundary, the right of the owners of the island to accretions beyond that line was taken away, while at the same time they were no longer subject to loss or diminution of their land by reason of its submergence “through the avulsion of floods or freshets or through gradual erosion.”

Subsequent to the establishment, in 1865, of the State Commissioners’ line, a considerable portion of the shore of the island, “on the so-called back channel, within the said high water, mark,” was washed away from time to time by heavy floods and freshets, so that a large part of the upland was slightly submerged, but not to an extent sufficient to permit of navigation. Some years ago, the United States Government, in order to increase the depth of water in the harbor of Pittsburgh, caused a dam to be constructed across the Ohio River a short distance below Brunot’s Island, known as the Davis Island Dam. And *615 the effect of'this dam, says the bill, by the increase of the depth of water in the channel, was to submerge Brunot’s Island to a far greater extent and to make the water over the complainant’s land navigable “at certain times, and for certain purposes,” where it was not navigable before.

In 1895, the Secretary of War, claiming to act under the authority of § 12 of the act of Congress of September 19, 1890, and knowing that the shore of Brunot’s Island had been washed away by floods and freshets, established a harbor line which ran across the complainant’s land within the line of the State Commissioners. It is further alleged that although the submerged land was generally covered by water, “it was not ordinarily navigable water,” and “has never constituted, nor does it now constitute a part of the public navigable waters of the United States; ” that no authority was conferred by the act of Congress upon the Secretary of War to regulate or interfere with the use of the complainant’s land by the establishment of harbor lines upon the same; and that even if the water over this land was in fact part of the public navigable waters of the United States, without being rendered thus navigable by the construction of the dam, still the Secretary of War had no right so to run the harbor line over the land in question as to deprive the complainant of its use and enjoyment. It was the right of the complainant, the bill avers, to repair the damage caused by floods and fre'shets and to reclaim the submerged portion by filling in or wharfing, “keeping at all times within the lines of the part that had been torn away by the violence of the waters.”

In 1907, the Secretary of War, claiming authority under § 11 of the act of Congress of March 3, 1899, against the complainant’s protest, changed the harbor line. The report of the United State engineer at Pittsburgh stated that the conditions of high and low water had not changed, since 1895, but as along a part of the shore of the island, *616 the harbor line of 1895 ran several hundred feet outside high-water mark as it then existed, it seemed advisable to change it so as to coincide with the actual high-water mark. A copy of the report with the order of the Secretary of War, dated February 23,1907, was annexed to the bill and made a part of it. In this it is stated that the location of the proposed harbor lines was within the bed of the stream as it existed as a physical fact.

The bill further shows that to facilitate the delivery of coal for the operation of its power house on the island, the complainant desired to reclaim a part of it which had been submerged by establishing a coal wharf on the back, channel, where both the harbor line of 1895 and that of 1907 “ran some distance landward of the said State commissioners’ high water line.” According to the proposed plans, the wharf or pier was to extend over the complainant’s land and to cross both of the harbor lines to the State commissioners’ line. While these plans were being perfected, the Secretary of War, through his representative, the United States engineer officer at Pittsburgh, declared to the complainant that it had no right to build upon its land across either of the harbor lines, and he refused to permit the complainant to reclaim its land or to build its wharf thereon outside the harbor line of 1907. He threatened that if it undertook to do so, he would prevent it and cause the complainant and its employés “to be prosecuted and fined by the authorities of the Federal Government” for violations of the acts of Congress of September 19, 1890 (26 Stat. 426, c. 907), and March 3, 1899 (30 Stat. 1151, c. 425). It was further charged that if the Secretary of War had authority to fix the original harbor line of 1895, that his power was exhausted by what was then done, and that the harbor line of 1907 was wholly unauthorized.

In consequence of the severe penalties prescribed by the acts of Congress for the cpnstruction of buildings, *617 piers or wharves outside any harbor line established by the Secretary of War and by reason of the defendant’s threats of prosecution in case the complainant carried out its plan of reclamation and the construction of its wharf, the bill avers that the complainant is prevented from making use of its property; that the defendant’s action constitutes a taking of its property for public use without just compensation; that it is subjected in its endeavor, so long as the harbor line remains unmodified, to a multiplicity of criminal prosecutions; and that the harbor line is a cloud upon its title.

The provisions of the acts of Congress, referred to in the bill, are set forth in the margin. 1

*618 In demurring to the bill the defendant asserted that it was bad in substance, and also specially assigned the following grounds,

“1. This proceeding is virtually a suit against the United States.

“2. This Court has no jurisdiction to restrain the enforcement of a penalty or prosecution for violation of law.

“3. This Court has no jurisdiction to restrain the defendant from instituting criminal proceedings, against-complainant.

■ “4. This Court has no jurisdicion to declare or define harbor lines or boundary lines of land outside the District of Columbia and in-the State of Pennsylvania.

*619 “5. Theré is no jurisdiction in this Court to pass any decree removing cloud upon an alleged title of complainant in realty in the State of Pennsylvania,, nor to accomplish the same by declaring the harbor lines referred to in the bill null and void.”

First. If the conduct of the defendant constitutes an unwarrantable interference with property of the .Complainant, its resort to equity for protection is not to be defeated upon the ground that the suit is one against the United States. The exemption of the United States from suit does not protect its officers from, personal liability to persons whose rights of property they have wrongfully *620 invaded. Little v. Barreme, 2 Cranch, 170; United States v. Lee, 106 U. S. 196, 220, 221; Belknap v. Schild, 161 U. S. 10, 18; Tindal v. Wesley, 167 U. S. 204; Scranton v. Wheeler, 179 U. S. 141, 152. And in case of an injury-threatened by his illegal action, the officer cannot claim immunity from injunction process. The principle has frequently been applied with respect to state officers seeking to enforce unconstitutional enactments. Osborn v. Bank of United States, 9 Wheat. 738, 843, 868; Davis v. Gray, 16 Wall. 203; Pennoyer v. McConnaughy, 140 U. S. 1, 10; Scott v. Donald, 165 U. S. 107, 112; Smyth v. Ames, 169 U. S. 466; Ex parte Young, 209 U. S. 123, 159, 160; Ludwig v. Western Union Telegraph Co., 216 U. S. 146; Herndon v. C., R. I. & P. Ry. Co., 218 U. S. 135, 155; Hopkins v. Clemson College, 221 U. S. 636, 643-645. And it is equally applicáble to a Federal officer acting in excess of his authority or under an authority not validly conferred. Noble v. Union River Logging R. R. Co., 147 U. S. 165, 171, 172; School of Magnetic Healing v. McAnnulty, 187 U. S. 94.

The complainant did not ask the court to interfere with the official discretion of the Secretary of War, but challenged his authority to do the things of which complaint was made. The suit rests upon the charge of abuse of power, and its merits must be determined accordingly; it is not a suit against the United States.

Second. The second and third grounds of demurrer, specially stated, raise the question as to the jurisdiction of the court to restrain the defendant from instituting criminal proceedings.

A court, of equity, said this court in In re Sawyer, 124 U. S. 200, 210, “has no jurisdiction over the prosecution, the punishment or the pardon of crimes or misdemeanors.....To assume such a jurisdiction, or to sustain a bill in equity to restrain or relieve against proceedings for the punishment of offenses, ... is to invade *621 the domain of the courts of common law, or of the executive and administrative department of the government.” Harkrader v. Wadley, 172 U. S. 148, 170; Fitts v. McGhee, 172 U. S. 516, 531; 2 Story’s Eq. Jur., § 893. But a distinction obtains when it is found to be essential to, the protection of the property rights, as to which the jurisdiction of a court of equity has been invoked,,that it should restrain the defendant from instituting criminal actions involving • the same legal questions. .This is illustrated in the decisions of this court in which officers have been enjoined from bringing criminal proceedings to compel obedience to unconstitutional requirements. Davis & Farnum Mfg. Co. v. Los Angeles, 189 U. S. 207, 217, 218; Dobbins v. Los Angeles, 195 U. S. 223, 241; Ex parte Young, 209 U. S. 123, 161, 162; Western Union Telegraph Co. v. Andrews, 216 U. S. 165. In this, there is no attempt to restrain a court from trying persons charged with crime, or the grand jury from the exercise of its functions, but the injunction binds the defendant not to resort to criminal procedure to enforce illegal demands.

It is urged that the statute authorizing the Secretary of War to prevent encroachments upon navigable streams is a valid one, and that the decisions cited do not apply. The validity of the statute is not attacked, because of the assumption that it is not to be construed to contemplate or authorize the alleged deprivation of property. Where the officer is proceeding under an unconstitutional act, its invalidity suffices to show that he is without authority,- and it is this absence of lawful power and his abuse of authority in imposing or enforcing in the name of the State unwarrantable exactions or restrictions, to the irreparable loss of the complainant, which is the basis of the decree. Ex parte Young, 209 U. S. p. 159. Andasimilar injury may be inflicted, and there may exist ground for equitable relief, when an officer, insisting that he has the warrant of the statute, is transcending its bounds, and thus un *622 lawfully assuming to exercise the power of government against the individual owner, is guilty of an invasion of private property.

By § 12 of,the act of March 3, 1899 (30 Stat. 1151, c. 425), it was provided that every person and every corporation which should violate any provision of § 11, relating to the observance of harbor lines, or any rule ,or regulation made by the Secretary of War in pursuance of that section, should be guilty of a misdemeanor and punished by fine or imprisonment. By § 17 it was made the duty of district attorneys of the United States to prosecute all offenders whenever requested by the Secretary of War. If the complainant’s rights, as against the defendant, were as claimed, it was entitled to adequate protection. And, in- such case, the remedy might properly embrace the restraining of unfounded prosecutions.

Third. The fourth and fifth special grounds of demurrer assert that the Supreme Court of the District of Columbia had no jurisdiction to define boundaries in the State of Pennsylvania, or to remove a cloud upon title to land in that State.

In dealing with these, objections, it is important to observe the precise nature of the suit. It was not to determine a controversy as between conflicting claimants under the local law. It was not to restrain trespass.. Northern Indiana R. R. Co. v. Michigan Central R. R. Co., 15 How. 233; Ellenwood v. Marietta Chair Co., 158 U. S. 105. It was not brought to try the naked question of the title to the land. Massie v. Watts, 6 Cranch, 148, 158. While the complainant’s -title lay at the foundation of the suit, -and it would be necessary for the complainant to prove it, if denied, still if its title to the land under water were established or admitted to be as alleged, the question would remain whether the defendant in imposing restrictions upon the use of the property was acting by virtue of authority validly conferred by a general act of *623 Congress. This was the principal question which the complainant sought to have determined. The defendant is within the District, amenable to the process of the court. There is no ground upon which it may be denied jurisdiction to decide whether he should be restrained from continuing his opposition to the complainant’s plan of improvement. Rather should it be said that the case falls within the general rule sustaining the jurisdiction of a court of equity which has control of. the person of the defendant and may compel obedience to its decree. Phelps v. McDonald, 99 U. S. 298, 308.

Fourth. Assuming that the court had jurisdiction, we are brought to a consideration of the equity of the bill.

It has been held that the establishment of a general system of harbor lines, for the protection of commerce and navigation, is not of itself an injury to property and cannot be restrained. Yesler v. Washington Harbor Line Commissioners, 146 U. S. 646, 656; Prosser v. Northern Pacific R. R. Co., 152 U. S. 59, 64, 65. But it has also been recognized that a different question arises when active measures are taken against an. individual proprietor to maintain a location of limits in alleged violation of his private rights and thus to prevent him from enjoying what is asserted to be the lawful use of his property. Prosser v. Northern Pacific R. R. Co., supra.

The complainant starts with the lines as laid down, in' 1865, by the State Commissioners. These lines are averred to.be “exactly in accordance with the then existing actual ordinary high and low water marks.” The argument is (1) that, independently of the effect of the. statute of Pennsylvania, the washing away of the banks, and the submergence of a portion of the island, dining the subsequent , years worked no loss of title, but that it remained absolute, including the right of reclamation and improvement of the submerged land inside the former line of high water; and (2) that, by virtue of the statute, the *624 boundary was permanently fixed by the State Commissioners’ high-water line and no subsequent encroachment of the water could affect the rights of the owner.

. (1)' It is the established rule that a riparian proprietor of land bounded by a stream, the banks of which are changed by the gradual and imperceptible process of accretion or erosion, continues to hold to the stream as his boundary; if his land is increased he is not accountable for the gain, and if it is diminished hé has no recourse for the loss. But where a stream suddenly and perceptibly abandons its old channel, the title is not affected and the boundary remains at the former line. Rex v. Yarborough, 3 B. & C. 91; S. C., 2 Bligh, N. S. 147; Gifford v. Yarborough, 5 Bing. 163; New Orleans v. United States, 10 Pet. 662, 717; Banks v. Ogden, 2 Wall. 57; County of St. Clair v. Lovingston, 23 Wall. 46, 67, 68; Jefferis v. East Omaha Land Co., 134 U. S. 178, 190-193; St. Louis v. Rutz, 138 U. S. 226, 245; Nebraska v. Iowa, 143 U. S. 359; Shively v. Bowlby, 152 U. S. 1, 35; Hale, De Jure Maris, Ch. 1, 4, 6, Hargrave’s Law Tracts; Mulry v. Norton, 100 N. Y. 424. The doctrine that the owner takes the risk of the increase or diminution of his land by the action of the water applies as well to rivers that are strong and Swift, to those that overflow their banks, and whether or not dykes and other defenses are necessary to keep the water within its proper limits. It is when the change in the stream is sudden, or violent, and visible, that the title remains the same. It is not enough that the change may be discerned by comparison at two distinct points of time. It must be perceptible when it takes place. “The test as to what is gradual and imperceptible in the sense of the rule is, that though the witnesses may see from time, to time that progress has been made, they could not perceive it while the process was going on.” County of St. Clair v. Lovingston, supra (p. 68).

We are confined to the allegations of the bill. We have *625 not the advantage of proof and findings, or even of a particularized description in the bill itself, as to the precise character of the alterations in the banks of Brunot’s Island which took place during the long period to which the' bill refers. It is alleged ‘ ‘ that subsequent to the establishment in 1865 by said Commissioners of the line of high water mark, as aforesaid, a considerable amount of the soil of the shore of said Brunot’s Island on the so-called back channel, within the said high water mark was washed away from time to time by heavy floods and freshets, so that a large part of the upland of the island^ that is the land above high water mark, became and was overflowed and slightly submerged by water, but said land was not submerged to an extent súfficient to permit of navigation of any kind thereover.” There is no other statement on the point save that the bill asserts that the complainant was entitled to reclaim, “keeping at all times within the lines of the part that had been torn away by the violence of the waters.”

It is manifest that thesé allegations are inadequate to support the complainant’s contention. The determining words are that the land was “ washed away from time to time by heavy floods and freshets,” and the reference is to what occurred in many years. This is far from a Statement that at any particular time there was such a sudden, violent, and visible change as to justify a departure from the ordinary rule which governs accretion and diminution albeit the stream suffer wide fluctuations in volume, the current be swift, and the banks,afford slight resistance to encroachment.

For example, the general principle of accretion, which has that of diminution as its correlative, applies to such rivers as the Mississippi and the Missouri, notwithstanding the extent and rapidity of the changes constantly effected. Jefferis v. East Omaha Land Co., supra; Jones v. Soulard, 24 How. 41; Saulet v. Shepherd, 4 Wall. 502; *626 County of St. Clair v. Lovingston, supra; St. Louis v. Rutz, supra. In Nebraska v. Iowa, supra, the question concerned the boundary between the two States, which, by the acts of admission, was the middle of the main channel of the Missouri River. Between 1851 and 1877, in the vicinity of Omaha, there were marked changes in the course of this channel so that in the latter year it occupied a very different bed from that through which it flowed in the former year. The opinion of the court describes in detail the physical conditions along the river. The court said (pp. 368-370): “The current is rapid, far above the average of ordinary rivers; and by reason of the snows in the mountains there are two well known rises in the volume of its waters, known as the April and June rises. The large volume of water pouring down at the time of these rises, with the rapidity of its current, has great and rapid action upon the loose soil of its banks. . . . The only thing which distinguishes this river from other streams, in the matter of accretion, is in the rapidity of the change caused by the velocity of the current; and this in itself, in the very nature of things, works no change in the-principle underlying the rule of law in respect thereto. ,Our conclusions are that, notwithstanding the rapidity of the changes in the course of the channel, and the washing from the one side and on to the other, the law of accretion controls on the Missouri River, as elsewhere; and that not only in respect to the rights of individual landowners, but also in respect to the boundary lines between States. The boundary, therefore, betwfeen Iowa and Nebraska is a varying line, so- far as affected by these changes of diminütion and accretion in the mere washing of the waters of the stream.” -And, in the same case, the decision clearly points the distinction between the losses and gains thus described, and an abrupt, visible change where at one place, at a particular time, the river having “pursued a course in the nature of an ox-bow, suddenly *627 cut through the neck of the bow and made for itself a new channel” (p. 370).

The present case falls within the category first mentioned, and according to general principles of law the owner would bear the losses caused by the washings of the river.

The bill also alleges that “some years ago the United States Government, in the interest of navigation and in order to increase the depth of water in the harbor of Pittsburgh, caused a dam to be constructed across the Ohio River a short distance below said Brunot’s Island known as the Davis Island Dam. The effect of this dam was to very decidedly increase the depth of the water in the channel back of Brunot’s "Island, and to cause the water of the river to flow higher upon the land of your orator, and to submerge same to a far greater éxtent and in fact to make said water which submerged your orator's land navigable at certain times, and for certain purposes, which was not navigable before the construction of said dam.”

It will be observed that it is said that the United States caused the erection of the dam in the interest of navigation. The complainant purchased the island subsequently, in the year 1896. And we are not concerned here with the question whether there was any appropriation of land of the former owner by the United States and a cause of action arose to recover its value. Gibson v. United States, 166 U. S. 269; United States v. Lynah, 188 U. S. 445; Bedford v. United States, 192 U. S. 217; Manigault v. Springs, 199 U. S. 473; C., B. & Q. Ry. v. Drainage Commissioners, 200 U. S. 561, 583, 584. So far as the bill shows the dam was lawfully built, and the allegations with respect to it wholly fail to state afty case entitling the1 complainant to relief by reason Of its construction.

(2) The complainant, however, insists that the effect of the Pennsylvania statute was to fix the boundary of the island permanently at the State Commissioners’ high- *628 water line, and hence that within that line it was entitled to make the desired reclamation and improvement.

This statute (act of sixteenth April, 1858), provided thg,t the Commissioners’ lines approved by the court should “forever after be deemed, adjudged and taken firm and stable for the purposes aforesaid.” The Supreme Court of Pennsylvania has held that the purpose of the act was to regulate the rights of the public in respect to navigation and to prevent private rights from being exercised to the prejudice of the public interest. Wainwright v. McCullough, 63 Pa. St. 66; Zug v. Commonwealth, 70 Pa. St. 138, 142; Poor v. McClure, 77 Pa. St. 214, 219; Allegheny City v. Moorehead, 80 Pa. St. 118, 139, 140. In Wainwright v. McCullough (1869), supra, that court, holding that the statute was not applicable to disputed boundaries between private owners, considered the navigable character of the rivers to which it related, the extent of riparian rights under the law of the State, and the meaning of the act in the light of the mischief which it was intended to correct. The court said (p. 73):

“In order to arrive at the legal effect'of the lines established by the commissioners under that act, we must ascertain its true purpose; and to reach this, it becomes necessary to examine the navigable character of the rivers Allegheny, Monongahela and Ohio, and the rights of the riparian proprietors upon their banks. These rivers are among the.largest in the state; larger than the Schuylkill and Lehigh, recognized as navigable in the early history of the province, and have been repeatedly held by name to be rivers naturally navigable, and therefore classed with the Delaware and Susquehanna: Carson v. Blazer, 2 Binney, 478; Shrunk v. Schuylkill Nav. Co., 14 S. & R. 79, 80; Hunter v. Howard, 10 S. & R. 244. Many acts have- been passed declaring tributaries of these rivers navigable. But an act perhaps most pertinent to this controversy is that of 8th April, 1785, 2 Sm. Laws, 317, *629 regulating the taking up of lands within .the new purchase, of which the 13th section expressly excepts islands in the Ohio, Allegheny and Delaware.

“This being the navigable character of the stream, the-rights of the riparian owners are settled by numerous decisions, a few of which may be referred to: Carson v. Blazer, supra; Shrunk v. Schuylkill Nav. Co., supra; Ball v. Slack, 2 Whart. 508; Zimmerman v. Union Canal Co., 1 W. & S. 346; Bailey v. Miltenberger, 7 Casey, 37; McKeen v. Delaware Div. Canal Co., 13 Wright, 424; Tinicum Fishing Co. v. Carter, 11 P. F. Smith, 21, opinion by Sharswood, J., decided last winter at Philadelphia. From these and other cases, it will appear that the absolute title of the riparian proprietor extends to high-water mark only, and that between ordinary high and ordinary low water-mark, his title to the soil is qualified, it being subject to the public rights of navigation over it, and of improvement of the stream as a highway. He cannot occupy to the prejudice of navigation or cause obstructions to be placed upon the shore between these lines, without express authority of the state.

“The case of Bailey v. Miltenberger, 7 Casey, 37, decided, in 1856, doubtless had something to do in turning public attention to the shores of the streams surrounding the city of Pittsburg, which led to the passage of the Act of 1858, for the purpose of defining the low and high waterlines. It referred to the mistaken idea entertained by some proprietors of making ground for their mills, by depositing cinders on the shore between low and high water .marks. 'The Allegheny and many other navigable rivers ’ (says the opinion) ' do not, at the time of low water, occupy over one-third of their bed; and it would be most disastrous to allow every owner to fill out his land to low water-mark.’ This state of affairs, for these rivers had been seriously encroached upon at and opposite Pittsburg, *630 no doubt led to the Act of 16th April, 1868, Pamph. L. 326. It begins by a recital, ‘Whereas, The lines of lands on and along the shores at the rivers at and near the city of Pitts-burg, in the county of Allegheny, have never yet been clearly ascertained, and as it is important to the owners of such lands, the persons navigating the waters of, and the corporations adjacent to, such rivers, and to all parties interested, to know and to have their several rights and privileges in extension and limitation ascertained and defined; therefore,’ &c. The first impression arising from this language might seem to be that the law was intended to ascertain and fix these high and low water lines to end all controversies, private as well as public. But a careful consideration of its purpose and provisions shows that it is not applicable to disputed boundaries between private owners, but was intended to regulate the respective rights of the public and the landowners, over whose property the right of navigation extends between high and low water lines.

“The effect of the lines as established is thus stated: ‘the lines so approved shall for ever after be deemed, adjudged and taken, firm and stable for the purposes aforesaid.’ If we seek for the ‘aforesaid’ purposes, the act discloses’none but those relating to the public interest and that of the riparian owner. Then if we advert to the power of the state over navigable streams, as stated in the authorities cited, we discover that it is plenary over the subject of navigation and the improvement of thesé natural channels of commerce, while the ownership of the riparian proprietor is qualified between the lines of low and high water. The legislature may, therefore, with great propriety define the bounds of high and low water, by means of a suitable commission, for the purpose of regulating the public right, so as not to conflict with private interests, and to prevent private rights from being exercised *631 to the prejudice of public interests; for example, to prevent the shores from being filled up with great-banks of cinders.”

In Allegheny City v. Moorehead (1875), supra, the question was presented whether by the 'fixing of water lines .under the act of 1858, title had been vested in the city of Allegheny or lot owners,' so as to defeat the claim of the plaintiff Moorehead under a subsequent patent from the State. The court said (p. 139): “Nor can the operation of the Act of 1858 be extended by the act of the commissioners in running out. the low-water line of the northern shore of the river to include a part of what was Killbuck island. It was not the purpose of the commissioners to transfer titles, but to mark the boundaries- of riparian rights, so as to make them certain and permanent in their extent. So it was not the intention of the framers of the Act of 1858 to pass titles to lands, or to ascertain boundaries between individuals;- but it was their purpose to regulate the right-of navigation along the shores of these rivers by establishing high-, and low-water lines, which would definitely ascertain and fix the extent to which the ■right could be exercised; and the extent to which the owners of the land could exercise their own rights under the law of the state.”

It is contended for the complainant that the effect of the statute was to secure to riparian owners complete protection against any loss of their land, or of the right to build upon it, by reason of the gradual washing away of the banks of'the river; that the State chose to resign to the riparian proprietors its right to such additions from the moving landward of the low-water mark, and required the owner at the same time to surrender in the interest of navigation his right to alluvion. In support, the complainant cites the opinion of. the Court of Common Pleas No. 2 of Allegheny County in Briggs v. Pheil (1894), 42 Pittsburgh Legal Journal, p. 18, in which it is said with respect to the-same statute: “At the passage of this act *632 the riparian owner owned absolutely to high water mark, and had a qualified property to low water mark, and outside of the low water mark the. title to the soil was in the State. • It seems to us there can be no doubt that the State had power to enact that thereafter the legal limits of the' property should remain unchanged, either by gradual accretions or by gradual cutting- away. This in our opinion was intended to be done and was done by the Act of Assembly and the proceedings thereunder. . . . It seems to us that the establishing of these lines,.at least, .as between the State and rip'arian owners, fixed the lines for the.future.
