56 JOURNEY TO THE SHORES 
on moving the same compass about thirty yards 
to the west part of the islet, the needle became 
horizontal, traversed freely, and pointed to the 
magnetic north. The dipping needle being landed 
on the S.W. point of the islet, was adjusted as 
nearly as possible on the magnetic meridian by 
the sun’s bearings, and found to vibrate freely, 
when the face of the instrument was directed to 
the east or west. The mean dip it gave was 
80° 37’ 50". When the instrument was removed 
from the N.W. to the S.E. point, about twenty 
yards distant, and placed on the meridian, the 
needle ceased to traverse, but remained steady 
at an angle of 60°. _On changing the face of the 
instrument, so as to give a S.E. and N.W. 
direction to the needle, it hung. vertically. The 
position of the slaty strata of the magnetic ore is 
also vertical. Their direction is extremely irre- 
gular, 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. 
We began the ascent of Trout River early in 
the morning of the 27th, and inthe course of the
