88 THE ICE AGE IN CANADA. 



"Dr. Armstrong, previously quoted, notes the occur- 

 rence of granitic and other crystalline rocks, not only on 

 the south shore of Baring island, but also on the hills 

 inland. These, from what is now known of the region, 

 can scarcely be supposed to have come from elsewhere 

 than the continental land to the southward. 



" In an account of the scientific results of the ' Polaris ' 

 expedition (Nature, Vol. IX.), it is stated of the west 

 coast of Smith's sound, north of the Humboldt glacier, 

 that 'wherever the locality was favourable, the land is 

 covered by drift, sometimes containing very characteristic 

 lithological specimens, the identification of which with 

 rocks of South Greenland was a very readily accomplished 

 task. For instance, garnets of unusually large size were 

 found in latitude 81 3', having marked minerological 

 characters by which the identity with some garnets from 

 Tiskernaes was established. Drawing a conclusion from 

 such observations, it became evident that the main line of 

 the drift, indicating the direction of its motion, runs from 

 south to north.' It should be stated, however, that Dr. 

 Bessels, who accompanied the ' Polaris ' expedition, regards 

 these erratics as certainly not transported by glaciers, 

 but by floating ice, and as showing that the current of 

 Davis' strait was formerly to the north, and not to the 

 south, as at present. (Quoted from Bulletin de la Soc. de 

 Geographic, Paris, March, 1885, in Arctic Manual, p. 553.) 



" It may be mentioned, as bearing on the general ques- 

 tion here referred to, that Dr. Bell has found evidence of 

 a northward or north-eastward movement of glacier ice in 

 the northern part of Hudson bay (Annual Report Geol. 

 Survey of Canada, 1885, p. 14, DD),with distinct indications 

 of eastward glaciation throughout Hudson strait. (Report 

 of Progress, Geol. Survey of Canada, 1882-84, p. 36, DD.)
