The untiring Champlain, exploring, surveying, sounding, had made charts of all the principal roads and harbors; and now, pursuing his research, he entered a river which he calls La Riviere des Etechemins, from the name of the tribe of whom the present Passamaquoddy Indians are descendants. Near its mouth he found an islet, fenced round with rocks and shoals, and called it St. Croix, a name now borne by the river itself. With singular infelicity this spot was chosen as the site of the new colony. It commanded the river, and was well fitted for defence: these were its only merits; yet cannon were landed on it, a battery was planted on a detached rock at one end, and a fort begun on a rising ground at the other. At St. Mary's Bay the voyagers thought they had found traces of iron and silver; and Champdore, the pilot, was now sent back to pursue the search. As he and his men lay at anchor, fishing, not far from land, one of them heard a strange sound, like a weak human voice; and, looking towards the shore, they saw a small black object in motion, apparently a hat waved on the end of a stick. Rowing in haste to the spot, they found the priest Aubry. For sixteen days he had wandered in the woods, sustaining life on berries and wild fruits; and when, haggard and emaciated, a shadow of his former self, Champdore carried him back to St. Croix, he was greeted as a man risen from the grave. In 1783 the river St. Croix, by treaty, was made the boundary between Maine and New Brunswick. But which was the true St. Croix? In 1798, the point was settled. De Monts's island was found; and, painfully searching among the sand, the sedge, and the matted whortleberry bushes, the commissioners could trace the foundations of buildings long crumbled into dust; for the wilderness had resumed its sway, and silence and solitude brooded once more over this ancient resting-place of civilization.
