We proceeded to the northward, along the eastern side of a deep bay of the lake, passing through various channels, formed by an assemblage of rocky islands; and, at sunset, encamped on a projecting point of the north main shore, eight miles from Fort Providence.

To the westward of this arm, or bay, of the lake, there is another deep bay, that receives the waters of a river, which communicates with Great Marten Lake, where the North-West Company had once a post established.

The eastern shores of the Great Slave Lake are very imperfectly known: none of the traders have visited them, and the Indians give such loose and unsatisfactory accounts, that no estimation can be formed of its extent in that direction.

These men say there is a communication from its eastern extremity by a chain of lakes, with a shallow river, which discharges its waters into the sea.

This stream they call the Thlouee-tessy{54}, and report it to be navigable for Indian canoes only.
