exclusive right might be gained by an exclusive occupancy betwixt the shores, he would have been in error; but he pointedly said, that no other advantage could be had on the water than was had from the ownership of the land. But the wrong charged in the declaration is a disturbance, not of the plaintiff’s easement in the landing, but of an alleged right to an ancient ferry; and hence, it is argued, the evidence did not support the count. Had there been a prayer for direction to that effect, it must have prevailed, for the variance would have been fatal; but nothing like it is perceptible on the record: and, indeed, to have defeated the plaintiff on that .ground, would only have protracted the contest, by reserving the determination of the right for another law suit. In starting the point here, the defendant has slipped his time.
The title to the locus in quo is in the defendant’s lessor, and a .material question was whether the plaintiff had not acquired an exclusive right to use it, by a presumptive grant of one of the lessor’s predecessors; as to which, the judge charged that a grant .presumed from exclusive enjoyment is also exclusive. The extent of the right is doubtless determinable by the nature of the use; and the principle admits of a ready application to positive enjoyment, in order to carry the right to the extent of it, the difficulty being to .know whether it may not be carried even further by a want of actual participation on the other side. There is a plain implication of exclusive right, where the full benefit of the supposed grant could not be had from a concurrent enjoyment of it; as in the case of a pew barely sufficient to accommodate the occupant’s family. In the case of a way, the right is not necessarily exclusive, as was admitted in Kirkham v. Sharp, 1 Whart. 333. The rule seems to be, that the grant shall not be extended beyond the purpose to be .answered by it; nor ought it in reason to be. The presumption being that there was an actual grant, there is no room to suppose the grantee paid for, or the grantor parted with, more than was adequate to the purpose. Accordingly, in Martin v. Goble, *2 Camp.* 322, a plaintiff who prescribed for a window which admitted more light than was necessary for the business of a madhouse, of which it was part, was not allowed to maintain an action for the ¡erection of a wail which shut out the excess. The proper inquiry below, then, was whether the privilege to land passengers on the .defendant’s soil, would have been curtailed by a concurrent use of it; and it presented a question of fact which was, perhaps, not of easy solution. The place was used only at high, or very low water, and at irregular times of the day. A common landing might be alternately used without collision, by boats plying exactly at stated intervals, and even that is barely possible; but the difficulty is insurmountable where, as on our fresh water rivers, the ferry boat plies whenever a passenger presents himself. In all such cases, the jury ought to presume the right to be exclusive, whenever its value would be lessened, in the least degree, by participation. In
