About twenty miles beyond Chien Lake, and after passing Jourdan's Portage occurs what is called by Franklin 'Viscous Lake, ' the water of which is believed by the voyageurs to oppose extraordinary resistance to a canoe. I myself took a paddle, and found the fact very perceptible; but the cause was no doubt a tacit agreement of the men to relax their own efforts. The water is pure and tasteless, but I had no means of ascertaining its density. LXXVI. June 5.--Observed at a small lake on the height of land at the first 'set down' above the hill, in the Prairie Portage, which is thirty miles from Chien Portage, and marks the height of land, 887 feet above Lake Superior (Dawson).
