230 CRUISE OF THE NEPTUNE 



siderable volume of evidence to show that the main direction 

 of movement of erratics was northward. Thus, boulders of 

 granite supposed by Prof. Haughton to be derived from North 

 Somerset are found 100 miles to the northeastward, and pebbles 

 of granite, identical with that of Granite point, also in North 

 Somerset, occur 135 miles to the northwest. The east side of 

 King-William land is also said to be strewn with boulders like 

 the gneiss of Montreal island, to the southward. Prof. Haugh- 

 ton shows the direction and distance of travel of some of these 

 fragments by arrows on his geological map of the Arctic 

 archipelago, and reverts to the same subject on pages 393-394, 

 pointing out the general northward movement of ice indicated, 

 and referring the carriage of the boulders to floating ice of the 

 glacial period.' 



' Near Princess Royal island, in Prince of Wales strait, and 

 also on the coast of Prince of Wales island, the copper said to 

 be picked up in large masses by the Eskimos may be supposed 

 to be derived from the Cambrian rocks of the Coppermine river 

 region to the south, as it is not probable that it occurs in place 

 anywhere in the region of horizontal limestone where it is 

 found.' 



' Dr. Armstrong, previously quoted, notes the occurrence of 

 granitic and other crystalline rocks, not only on the south' shore 

 of Baring land, but also on the hills inland. These, from what 

 is 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 expedi- 

 tion, it is stated of the west coast of Smith sound, north of the 

 Humboldt glacier, that " wherever the locality was favourable 

 the land is covered by drift, sometimes containing very charac- 

 teristic lithological specimens, the identification of which with 

 rocks of South Greenland was a very easily accomplished task. 

 For instance, garnets of unusual large size were found in lati-
