The old gentleman was one of the selectmen of the town that year; and an old law, or municipal regulation, required that one or more of the selectmen should walk the town lines--follow round the town boundaries on foot--once a year, to see that the people of adjoining towns, or others, were not trespassing. The practice of walking the town lines is now almost or quite obsolete, but it was a needed precaution when inhabitants were few and when the thirty-six square miles of a township consisted mostly of forest. At this time the southern half of our town was already taken up in farms, but the northern part was still in forest lots. The selectmen usually walked the north lines only. When the state domain, almost all dense forest, was first surveyed, the land was laid off in ranges, so-called, and tiers of lots. The various grants of land to persons for public services were also surveyed in a similar manner and the corners and lines established by means of stakes and stones, and of blazed trees. If a large rock happened to lie at the corner of a range or lot, the surveyor sometimes marked it with a drill. Such rocks made the best corners. Usually the four corners of the town were established by means of low, square granite posts, set in the earth and with the initial letter of the township cut in it with a drill. As if it were yesterday I remember that sharp, cold morning. Hard-frozen snow a foot deep still covered the cleared land, and in the woods it was much deeper. The first heavy rainstorm of spring had come two days before, but it had cleared off cold and windy the preceding evening, with snow squalls and zero weather again. Nevertheless, Addison and I were delighted at the old Squire's proposal, especially since the old gentleman had hinted that we could have the fee, which was usually four dollars when two of the selectmen walked the lines and were out all day. "Go to the northeast corner of the town first," the old Squire said. "The corner post is three miles and a half from here; you will find it in the cleared land a hundred rods northeast of the barn on the Jotham Silver place. Start from there and go due west till you reach the wood-lot on the Silver farm. There the blazed trees begin, and you will have to go from one to another. It is forest nearly all the way after that for six miles, till you come to the northwest town corner. "You can take my compass if you like," the old Squire added. "But it will not be of much use to you, for it will be easier to follow the blazed trees or corner stakes. Take our lightest axe with you and renew the old blazes on the trees." He apparently felt some misgivings that we might get lost, for he added, "If you want to ask Thomas to go with you, you may."
