to two feet in depth, and from twenty to thirty-two inches in 
width, and ten or more feet in length. These grooves are finely 
polished and striated, resembling those with which geologists are 
familiar on Kelly’s Island, Lake Erie. Like the corresponding 
grooves on Kelly’s Island, some of these also turn around the 
southern point in graceful curves, adjusting themselves to the 
retreating face of the rock-wall. That the motion of the ice 
here was to the south is evident not only from the direction of the 
striz, but from the fact that the stoss side of the glaciated rocky 
projections are towards the north. That they are due to glacial 
action, and not to icebergs, is evident both from their character 
and from their analogy to numerous facts farther to the north, 
which are unquestionably connected with true glaciers. 
Vancouver’s Island, which trends parallel with the shore of the 
continent, northwest by southeast, is nearly three hundred miles 
in length, and from fifty to seventy-five in breadth. In character 
it seems but a continuation of the Coast Range of mountains, with 
numerous peaks rising from four to seven thousand feet above 
the sea. The shore-line of the continent upon the northeastern 
side of the Strait of Georgia is formed by a continuation of the 
Cascade Range, with a general elevation of from three to eight 
thousand feet, penetrated in numerous places to a distance of 
seventy-five miles by inlets or fiords several miles in width. Mr. 
rge Dawson has described the glacial phenomena in Bute 
Inlet, which enters the Strait of Georgia about opposite the centre 
of Vancouver’s Island, in latitude 50° 30’. He describes the 
chasm (see Quarterly Fournal of Geolog. Soc., vol. xxxiv. p. 89) 
as forty miles in length, surrounded by mountains, rising in some 
places in cliffs and rocky slopes from six to eight thousand feet. 
“The islands about its mouth are roches moutonnées, polished and 
ground wherever the original surface has been preserved.” 
The mountains on either side the Strait of Georgia, and north- 
westward to the head of Lynn Channel, in latitude 59° 20’, are 
snow-clad throughout the whole season. The shores are every- 
where rocky and precipitous, retaining in many places far up 
their sides glacial striz parallel with the direction of the numer- 
ous channels which thread their way through the Alexander 
Archipelago. I had opportunity at Loring, on the western shore 
of Revilla Gigedo Island, to examine minutely the striation on 
the shores and islands of the bay. There are now no glaciers
