A river was pointed out bearing south from our encampment, which is said to rise near Great Marten Lake.
Red-Rock Lake is in general narrow, its shelving banks are well clothed with wood and even the hills, which attain an elevation of four hundred or five hundred feet, are ornamented halfway up with stunted pines.
On June 30 the men, having gummed the canoes, embarked with their burdens to descend the river; but we accompanied the Indians about five miles across a neck of land, when we also embarked.

The river was about two hundred yards wide and, its course being uninterrupted, we cherished a sanguine hope of now getting on more speedily, until we perceived that the waters of Rock-nest Lake were still bound by ice and that recourse must again be had to the sledges.

The ice was much decayed and the party were exposed to great risk of breaking through in making the traverse.

In one part we had to cross an open channel in the canoes, and in another were compelled to quit the Lake and make a portage along the land.

When the party had got upon the ice again our guide evinced much uncertainty as to the route.
