The
Dipping Needle, Being Landed On The South-West 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 degrees 37
minutes 50 seconds.
When the instrument was removed from the North-West
to the South-East point about twenty yards distant and placed on the
meridian the needle ceased to traverse but remained steady at an angle of
60 degrees. On changing the face of the instrument so as to give a
South-East and North-West direction to the needle it hung vertically. 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 South-West
course.
TROUT RIVER.
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. This cascade is named the Trout Fall, and the beauty of the scenery
afforded a subject for Mr. Hood's pencil.
