The Delaware river is a public navigable river: McKeen v. Delaware Division Canal Co.,
Below its ordinary lоw water the ownership of the soil under the river is in the Commonwealth, the title of the abutting riparian owner extending only to ordinаry low water mark, subject to the rights of navigation, fishery, and improvement of the stream between high and low water marks: Carson v. Blazer, 2 Binney 475; Flanagan v. Philadelphia,
The court below finds the entirе tract was below ordinary low water mark in the year 1885; beginning at that time and continuing to 1895, with the knowledge and consent of plaintiffs, the bottom of the river in front of their property, both above and below ordinary low water mark, was used as a dumping ground fоr materials dredged from the channels of the Delaware and Schuylkill rivers and other places, under the direction of оfficials of the United States government; the effect thereof, and of their construction and maintenance of Mifflin Bar dike (which extends along the entire frontage of Hog Island), was to accelerate the deposits in the river at this point; “аbout the year 1906, the United States Government pumped material, by means of hydraulic dredges, on the land above the oрen basin near the upper end of the dike. Sand, gravel and earth mixed with water found their way by gravity into the river, and further materiаlly raised the bottom of the river bed. Some of this material flowed back into the channel through the stone dike, and, to prevent this, plaintiffs were required by the United States engineers to construct a mud bank along the edge of the dike on the inside therеof; this was done in 1906. In the year 1912, a cross-bank was built by the plaintiffs......so that pumping could thereafter take place behind thе cross-bank without danger of the material flowing back into the water at any point. Since the construction of these bаnks, the area included behind
The court below further held, as a matter of law, the judgment in this case does not bind the Commonwealth, which was the original owner of the land below low water mark; but it decided plaintiffs nevertheless were' entitled to recover becаuse they had “presented evidence which, as between themselves and the defendant, and as against any defense rаised and presented by the defendant, clearly entitled them to judgment.”
In thus deciding the court below overlooked the rules of law applicable to this class of cases. An action for the purchase money of land is in legal effect a petition or bill for specific performance of the contract of purchase, and is governed by the same equitable principles: Nicol v. Carr,
The judgment of the court below is reversed, without prejudice to plaintiffs’ right to hereafter demand the * purchase money of said land whenever they can give to defendant a marketable title thereto.
