The act of walking over the boundaries of a district or piece of land, either for the purpose of determining them or of preserving evidence of them. Thus, in many parishes in England, it is the custom for the parishioners to perambulate the boundaries of the parish in rogation week in every year. Such a custom entitles them to enter any man’s land and abate nuisances in their way. Phillim. Ecc. Law, 1807; Hunt, Bound. 103 ; Sweet See Greenville y. Mason, 57 N. H. 385.
