252 Glaciation of British Columbia. — Dawson. 
Arctic coast of the Continent, and the Islands of the Archi¬ 
pelago off it, there is a considerable volume of evidence to 
show that the main direction of the movement of erratics was 
northward. The most striking facts are those derived from 
Prof. S. Haughton’s Appendix to M’Clintock’s Voyage, where 
the occurrence is described of boulders and pebbles from 
North Somerset, at localities of 100 and 135 miles north-east¬ 
ward and north-westward from their supposed points of 
origin. Prof. Plaughton also states that the east side of King- 
William’s Land is strewn with boulders of gneiss like that of 
Montreal Island, to the southward, and points out the general 
northward ice-movement thus indicated, referring the carriage 
of the boulders to floating ice of the Glacial Period. 
The copper said to be picked up in large masses by the 
Eskimo, near Princess-Royal Island, in Prince-of-Wales 
Strait, as well as on Prince-of-Wales Island, 7 has likewise, in 
all probability been derived from the copper-bearing-rocks of 
the Coppermine River region to the south, as this metal can 
scarcely be supposed to occur in place in the region of hori¬ 
zontal limestone where it is found. 
Dr. A. Armstrong, Surgeon and Naturalist to the “ Investi¬ 
gator,” notes the occurrence of granitic and other crystalline 
rocks not only on the south shore of Baring Land, but also on 
the hills at some distance from the shore. These, from what 
is now known of the region, must be supposed tb have come 
from the continental land to the southward. 
Dr. Bessels, again, remarks on the abundance of boulders 
on the shore of Smith’s Sound in lat. 81° 30 \ which are mani¬ 
festly derived from known localities on the Greenland coast 
much further southward, and adds: “Drawing a conclusion 
from such observations, it becomes evident that the main line- 
of the drift, indicating the direction of its motion, runs from 
south to north.” 8 
It may further be mentioned that Dr. R. Bell, of the Cana¬ 
dian Geological Survey, has found evidence of a northward or 
north-eastward movement of glacier-ice in the northern part 
of Hudson Bay, with distinct indications of eastward glacia¬ 
tion in Hudson Strait. 9 For the Northern part of the Great
