252 Glaciation of British Columhid. — IJaioso)i. 
Arctic coast of the Continent, and the Islands of tlie 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 IM") miles north-oast- 
ward and north-westward from their su})posed points of 
origin. Prof. Haughton also st;ites that the east side of King 
William's Land is strewn with l)Oulders of gneiss like that of 
Montreal Island, to the southward, :ind 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 u]) in large masses by the 
Eskimo, near Princess-Royal Island, in i'rince-of-Wales 
Strait, as well as on Prince-of-\V;iles island.' has likewise, in 
all prul)al)ility been derived from the (■(i])p(i-l)earing-rocks of 
the Coppermine River region to the south, as this metal can 
scarcely be supjiosed to occur in place in the region uf liori- 
zontal limostom' wliere 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. Tliese, from what 
is now known of the region, must be supposed to have come 
from the continental land to the southward. 
Dr. Bessels, again, remarks on \\w abundance of boulders 
on the shore of Smith's Sound in lat. 81° 30', which are mani- 
festly derived from known localities on the (ireenland coast 
much further southward, and adds :" Drawing a (•onrlusi(M'! 
from such observations, it l)ecomes evident that tlie main line 
of the drift, indicating the direction of its motion, runs from 
south to north."* 
It may further be mentioned that Dr. R. P)ell, of the Cana- 
dian (ieological Surve}', 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 i n Hudson Strait." For the Northern part of the (Ireat
