Lake Superior.

By a gentlemen just from Lake Superior, and who has given that region a more general and critical examination than any one with whom we have previously conversed, the following information is gained:

The strongest indication of the existence of copper ore is observable at the bluffs of St. Croix, near the Mills. North of the summit between the Mississippi and the Lake, the country is heavily timbered with white, yellow, & pine, spruce or fir and red and white cedar. None of the rivers emptying into the Lake are navigable, but all furnish an amount of hydraulic power beyond calculation. The soil, clay and rock are all red or redish. The ridges even the highest of them, are covered with marsh and ponds. The miners there are looking out a location-very little has yet been done.
