The first question that arises upon the state of facts presented by this bill of exceptions is, whether, at the time of the defendant’s purchase in 1844, his grantor had acquired a right of way across C by adverse user. And this depends upon the decision of the question whether, in the acquisition of an easement of this character, the user of an heir may be tacked to that of his ancestor, or the user of a grantee to that of his grantor. If such right of tacking does not exist, then no adverse right had been acquired ; for between 1796 and 1844, a period of forty-eight years, no single owner of A and B had used the way across C for a sufficient length of time to acquire a right.
As to the acquisition of a title to land by adverse possession, the law is well settled. It is fully stated in Sawyer v. Kendall, 10 Cush. 241. The disseisin of an heir, devisee or grantee may be tacked to that of an ancestor, devisor or grantor to create such title.
It is, however, denied that this doctrine applies to the adverse use of easements. But its application to easements is sufficiently sustained by authority. In 3 Kent Com. (6tb ed.) 443, 444, the doctrine is stated as follows: “ To render the enjoyment of any easement for twenty years a presumption juris et de jure, or conclusive evidence of right, it must have been continr ued, uninterrupted or pacific, and adverse, that is, under a claim *281of right, with the implied acquiescence of the owner. The term of enjoyment requisite for the prescription is deemed to be uninterrupted, when it is continued from ancestor to heir, and from seller to buyer.” In Hill v. Crosby, 2 Pick. 466, a right of way was held to be thus acquired by the successive user of father and son. In Sargent v. Ballard, 9 Pick. 251, where a right to use a wharf and dock was claimed, the question was discussed elaborately, and the doctrine was laid down that the right of tacking exists between ancestor and heir, grantor and grantee. In Kent v. Waite, 10 Pick. 138, the doctrine was applied to a right of way, and in Melvin v. Whiting, 13 Pick. 184, to a right of fishery. In Williams v. Nelson, 23 Pick. 141, it was applied to the right of a mill-owner to flow the land of his neighbor above his mill; and his own flowing was tacked to that of his predecessors under whom he claimed.
There is no reason for making any difference in this respect between titles to land and titles to easements. If the title has its basis in a presumed grant, privity of user tends as strongly to prove such grant as privity of seisin. Or if the title has its basis in considerations of public policy, for the quieting of titles, that policy applies as well to the adverse user of easements for twenty years as to the adverse possession of land.
But it is contended that, in order to create a privity of user, the easement must be expressly mentioned in the deed and conveyed by it. In support of this position it is said that, until the lapse of twenty years, the adverse user consists merely of a series of tortious acts, none of which have created any right; and since no right of way is as yet legally appurtenant to the land, it will not pass as an appurtenance, and therefore the user of the purchaser is not in privity with the user of his grantor, but is wholly independent of it. The principle that a disseisor of land cannot tack his possession to that of a prior disseisor under whom he does not claim, and with whom he had no connection, as stated in Melvin v. Proprietors of Locks & Canals, 5 Met. 32, and the cases there cited, is said to be applicable to such a case as this. On the same ground it is contended that, upon the death of the person who has used the way for less than *282twenty years, the subsequent user of his heir ought not to be tacked to his user, but is independent of it and disconnected with it, because, no right having been acquired by the ancestor, none could descend to the heir. The objection has apparently equal force in both cases, for in neither case does any title to the easement in express terms pass. Yet in the case of the heir it is settled by the authorities above referred to that his possession may be tacked to that of his ancestor. His user is regarded as a continuation of the user of his ancestor, on account of his privity of title to the land to which the easement has been claimed by both to be appurtenant. By the same course of reasoning the user of an easement by a grantee should be tacked to that of his grantor. It is a continuity of user under the same claim of title, though without any real transfer of title.
If we apply to it the theory of public policy for the quieting of titles, it presents a case where the owner of a tract of land has permitted the successive occupants of an adjoining lot, holding under one and the same title, to use a way over his land for twenty years, claiming that it was appurtenant to their lot, and without any objection on his part. His claim after that period is as stale in respect to the purchaser or heir as it would have been in respect to the original trespasser, and there is the same reason for closing the doors of the court against him in their favor as there would be in his favor. Or if we adopt the theory of a lost grant, which is the theory adopted in Tyler v. Wilkinson, 4 Mason, 397, and Williams v. Nelson, ubi supra, the privity of claim and its validity appear still more clearly. The lapse of twenty years has raised a conclusive presumption that a grant was made to the first occupant more than twenty years before. The constant user of the way is the proof of the grant. Of course, the whole occupation is presumed to have been under it.
In a similar manner the public may acquire a right of way over a man’s land. In such a case the persons who use the way are separate and independent of each other, and until twenty years have elapsed each of them is a trespasser. Their only connection is by privity of claim. This is the tie which, after *283the completion of twenty years, unites all their acts as conclusive evidence of a grant or dedication to the public.
In the present case it is to be remarked that it is not the owner of the lot C who denies the existence of the right of way. No proprietor of that lot appears to have denied it since 1796. But the denial comes from the owner of the lot A, whose grantors had successively used the way under claim of right, and at the time when the lot was sold to the defendant in 1844 the way had been thus used by them for a period of forty-eight years.
The court are of opinion that in 1844 the owner of A and B, when he sold the lot B to the defendant, owned as appurtenant to it a right of way to B across C, and that this right of way would pass by his deed to the defendant. But in order to make it of any use to the defendant, it was reasonably necessary to extend it across the grantor’s own lot A to Hall’s Lane. And if such extension of the way across his own land was reasonably necessary, the right would pass by his deed.
The question whether an easement passes from a grantor to his grantee as appurtenant to the land conveyed is not precisely the same as the question whether a right of way across the land of a stranger is created by necessity. The grantor’s deed is to be most strongly construed against him; and if an easement properly belongs to the granted premises, and has been used by him in-connection with the premises, it ought to pass as appurtenant to the land granted, though it is not mentioned in the deed, and though it subjects his other land to the servitude. The fact that the easement has been thus used and is merely convenient is not sufficient. Its use in connection with the land conveyed must be reasonably necessary. And any easement, as for example a right of way or of drainage, which can be thus regarded, passes as an appurtenance without being named Ewart v. Cochrane, 7 Jur. (N. S.) 925. James v. Plant, 4 Ad. & El. 765. Pyer v. Carter, 1 Hurlst. & Norm. 916. Salisbury v. Andrews, 19 Pick. 250. Thayer v. Payne, 2 Cush. 327. Huttemeier v. Albro, 18 N. Y. 48. New Ipswich Factory v. Batchelder, 3 N. H. 190. United States v. Appleton, 1 Sumner, 192.
*284The right of way having passed to the defendant as appurtenant to the lot B, it is not necessary to discuss the other questions which have been argued. Exceptions sustained.
