The identity of St. Croix Island was determined in 1798, by the commissioners appointed, under the treaty of 1783, to determine the boundary-line between New Brunswick and the territory of the United States. Holmes says, in _Annals of America_ (Cambridge, Mass., 1829), vol. i., p. 122, _note_ 1: "Professor (afterwards President) Webber, who accompanied the commissioners in 1798, informed me that they found an island in this river, corresponding to the French descriptions of the Island St. Croix, and, near the upper end of it, the remains of a very ancient fortification, overgrown with large trees; that the foundation stones were traced to a considerable extent; and that bricks (a specimen of which he showed me) were found there. These remains were, undoubtedly, the reliques of De Monts's fortification." Several cannon balls were also discovered while making excavations on this island, about 1853. The island has been known as Dochet's Island and Neutral Island; but in recent years it has been formally and appropriately named De Monts' Island. See Godfrey's _Centennial Discourse_ (Bangor, 1870), cited in _Champlain's Voyages_ (Prince Soc.), vol. ii., p. 33; also Williamson's _Maine_, vol. i., p. 88, and vol. ii., p. 578. 5 (p. 47).--George Weymouth, a Bristol navigator, entered Kennebec River in June, 1605. The stream was called by the natives Sagadahoc (sometimes spelled Sagadahock). Weymouth's enthusiastic reports led the Plymouth Company--of which Lord John Popham and Sir Ferdinando Gorges were leading members--to plant a colony in August, 1607, at first probably on Stage Island, but later on the shores of Atkins' Bay, ten miles up the Kennebec. Owing to the death of Popham, their chief patron, and other misfortunes, the colonists returned to England in 1608. For several years thereafter, Gorges and Sir Francis Popham--son of Lord John--fitted out trading and fishing expeditions to the region, but no permanent colony was again attempted on the Kennebec until 1630. Weymouth had serious difficulties with the natives (1605), and kidnapped several of them; the colonists themselves were, towards the close of their stay, cruel to their neighbors; the outrages in 1609 were doubtless the operations of visiting English traders. The boats and other English property seen by the French in 1611, at the Penobscot and Kennebec, of course belonged to traders, who were at this time numerous along the main shore. Cf. Williamson's _Maine_, vol. i., pp. 53, 191-239; and _Memorial Volume of Popham Celebration_, Aug. 29, 1862. (Portland, 1863).
