gives them a claim for compensation. The contrary doctrine, that, in order to develop the greatest public utility of a water-way, private convenience must often suffer without compensation, has been sanctioned by repeated decisions of the supreme court. The following are cases all involving that proposition: The Blackbird Creek Case, 2 Pet. 245; Gilman v. Philadelphia, 3 Wall. 713; Pound v. Turck, 95 U. S. 459; Wisconsin v. Duluth, 96 U. S. 379; South Carolina v. Georgia, 93 U. S. 4.
If it were made apparent to congress that any extension of the plaintiff’s present shore line into the river tended to impair the navigability of the stream, or its use as a highway of commerce, congress could authorize the agents of the United States to establish the present shore as the line beyond which no structures of any kind could be extended, and the plaintiff would have no claim for compensation. If the plaintiff could thus lawfully he prevented from appropriating to his private use any part of the submerged land lying in front of his shore-line, and the whole of it be kept subservient to the easement of navigation, how can it he successfully claimed that he must be paid for the small portion covered by the light-house 200 feet from the shore, which has been taken for a use as strictly necessary to safe navigation as the improved channel itself? The court of appeals of Maryland, whenever called upon to declare the nature of the title of the state and its grantees in the land at the bottom of navigable streams, has uniformly held that the soil below high-water mark was as much a part of the jus publicum as the stream itself. Day v. Day, 22 Md. 537. And in the leading Maryland case of Browne v. Kennedy, 5 Har. & J. 203, (decided in 1821,) discussing the nature of the property in the soil covered by navigable rivers in Maryland, it was said:
“It is very certain that by the common law the right [to the soil] was in the king of England, and it seems equally clear that he had the capacity to dispose of it sub modo. Whatever doubts are entertained on the subject, they probably have arisen from inattention to the distinction between the power of granting- an exclusive privilege, in violation or restraint of a common piscarial right or other common right, as that of navigation, and the power of granting the soil aqua cooperta, subject to the common user. The subject has, de oommuni pure, an interest in a navigable stream, such as the right of fishing and of navigating, which cannot be abridged or restrained by any charter or grant of the soil or fishery, since Magna Charta, at least. But the property in the soil may be transferred by grant, subject, however, to the jus publicum, whicli cannot be prejudiced by the jus privatum, acquired under the grant.”
The same doctrine has been recently enforced, with regard to the character of the ownership of New Jersey in the lands under the navigable waters of that state, by Mr. Justice Bradley in Stockton v. Railroad Co., 32 Fed. Rep. 19. It appears, therefore, that the private interest granted to the plaintiff in the soil in question was of necessity granted to him subject to the use which the United States is now making of it in aid of navigation, and that the special plea to plaintiff’s action of ejectment sets up a perfect defense to the action. The plaintiff’s replication to the defendant’s special plea simply avers that, when pos
