The opinion of the court was delivered, by
Agnew, J.The parties owned adjoining lands and had a partition fence between them, which had stood for more than twenty-one years. Each party had made one-half of it. Stoner, the defendant below, removed the portion of it which he had built, and set it about fourteen feet in upon his own land. Hunsicker sued him in trespass vi et armis, and recovered damages. The right of Stoner to remove the half of the fence is *515rested upon his supposed ownership of the materials in severalty. We think ownership of the materials, which entered into the structure of the fence, a slender foundation for the right claimed here, to remove a structure dedicated to important uses, the subject of legal duty and legal protection, a barrier erected as a landmark of boundary, a protection of property, and a means of preserving the peace of society.
Fences play an important part as the monuments of title, giving effect to the Statute of Limitations, and, after twenty-one years’ corresponding peaceable possession, controlling even original lines of survey: Brown v. McKinney, 9 Watts 565. Landmarks have had the benefit of protection under legal penalties, from the foundation of the province; a protection renewed and extended in the Act of 81st March 1860, § 153.
Legal duties also arise out of partition fences. According to the 5th section of the Act of 11th March 1842, Purd. of 1861, p. 476, the duty to repair or build in a reasonable time devolves upon the owner of adjoining improved land, and if not performed the opposite owner may repair or build, and recover the price in an action before a magistrate. In Stevens v. Shriver, 1 Casey 78, the duty to contribute and maintain was held even in a case where the boundary was in dispute. In Rangler v. McCreight, 3 Casey 95, the court held that either owner could insist upon a comrqon partition fence along their line between improved fields, and where the defendant’s cattle passed from his own field to the plaintiff’s by reason of the plaintiff’s neglect to build his part of the fence, the plaintiff could sustain no action for the trespass. The same principle is established by the Act of 1700, in relation to fences not built according to its requirements, viz.: “ at least five feet high, of sufficient rails or logs, and close at the bottom and the owner is made liable for all damages to cattle, hogs, &c., by driving or hunting them out, if his fence be unlawful.
The argument of the plaintiff in error overlooks another important principle, to wit, that fences are a part of the realty, and become affixed to it; so that they are no longer transitory, as personal estate. They pass by a sale of the farm, as much as the soil itself.
The building of a boundary fence is therefore a dedication of the materials to the realty. • It becomes an important part of the estate of each owner, subjecting him to legal duties, and cannot be removed at nleasure.
Judgment affirmed.
