The position of the slaty strata of the magnetic ore is also vertical.

Their direction is extremely irregular, being much contorted.
Knee Lake towards its upper end becomes narrower, and its rocky shores are broken into conical and rounded eminences, destitute of soil, and of course devoid of trees.

We slept at the western extremity of the lake, having come during the day nineteen miles and a half on a S.W.

course.
We began the ascent of Trout River early in the morning of the 27th, and in the course of the day passed three portages and several rapids.

At the first of these portages the river falls between two rocks about sixteen feet, and it is necessary to launch the boat over a precipitous rocky bank.
