It gradually decreased in breadth till it became a river, which is the third fork of the Missinippi, and its current being almost insensible, we entered the Clear Lake at ten A.M.on the 1st of July.

Of this lake, which is very large, no part is known except the south border, but its extent would lead us to conclude, that its evaporation must be supplied by another river to the northward, especially as the small channel that communicates with Buffalo Lake is motionless.

The existence of such a river is asserted by the Indians, and a shorter passage might be found by it across the height of land to Clear Water River, than the portage from the Methye Lake.
In Buffalo Lake, the wind was too strong for us to proceed, and we therefore encamped upon a gravel beach thrown up by the waves.

We embarked at three A.M.July 2d, and at four P.M.entered the mouth of the Methye River.

The lake is thirty-four miles in length, and fourteen in breadth.
