Upon the crest of the dividing ridge, very close to the source of the Southwest Branch, a large monument has been erected. It is the first point in the highlands, and from it the boundary runs along the crest in a southerly direction, passing near to the southeastern shore of the Portage Lake, and so on to a large monument erected on a small eminence on the east side of the Kennebec road. Thence it passes through a dwelling house called Tachereau's, which was standing there at the time the line was run; so, by a tortuous course, it runs to the top of Sandy Stream Mountain; thence, inclining to the southwest, it runs over Hog Back the First, as shown in the maps; thence toward Hog Back the Second, which it leaves on the north side. Further on, at the head of Leech Lake, there is a stream which divides its waters and flows both into Canada and into the United States. The boundary has been made to run up that stream a short distance from the fork where the waters divide to a second fork; thence between the streams which unite to form that fork, and then to ascend again the dividing ridge. A monument has been erected at the fork first mentioned, where the waters divide. As the boundary approaches the valley of Spider River it bends to the southeast, and, by a wide circuit over high and steep hills, it turns the head of Spider River; thence it bends to the northwest until it approaches within about 4 miles of Lake Megantic; thence it turns again south, having the valley of Arnolds River on the right and of Dead River on the left. It leaves Gasford Mountain in Canada, threads its way over very high ground between the head of Arnolds River and the tributaries of the Magalloway; inclines then to the north, so to the west, over very rocky, mountainous, and difficult country, leaving Gipps Peak in the United States, and turns by a sharp angle at Saddle Back to the south. After that it again inclines to the west, and then to the south, and again to the west, and passes the head of the Connecticut. About 3 miles and a half east of the head of the Connecticut there is a division of waters similar to that described near Leech Lake. The boundary runs down a stream from near its source to the fork where it divides, and then again follows the dividing ridge. The spot is noted on the map. After the boundary has passed the head of the Connecticut it runs to the northwest, descending into very low, swampy ground between the heads of Indian Stream and the tributaries of the St. Francis. Thus it passes on, bending again to the south of west, over a high hill, to the source of Halls Stream. Iron monuments have been erected at intervals along the highlands from the source of the Southwest Branch of the St. John to the source of Halls Stream, the position of each of which is shown upon the maps.
