AS A TRANSPORTING AGENT. PREST. 457 



In reference to erosion by drift ice noticed in my former 

 paper an exact counterpart of the peculiar markings and 

 furrows seen in Labrador is to be seen in the Mount Uniacke 

 gold district, Nova Scotia. There, about three-quarters of a 

 mile east of the 30-stamp mill, on several large exposures of 

 quartzite, are seen hundreds of the curved furrows and scratches 

 possible only with the irregular movements of storm-tossed 

 boulders. These scratched surfaces incline slightly toward a 

 shallow valley to the northwest, and show on that side the 

 strongest evidences of ice action. Some of the more protected v 

 portions show evidences of earlier glacial action, the striations- 

 varying from S. 8 to S. 16 E. 



In concluding these notes, I can only reiterate my opinions 

 of a year ago : 1st, that the drift ice from the Arctic performs 

 but an extremely infinitesimal part in the building of the accu- 

 mulation known as the Banks of Newfoundland ; 2nd, that 

 these banks had their origin in Pleistocene times, and are simply- 

 glacial debris worked over by the sea ; 3rd, that their terrestrial, 

 equivalents can be traced in the broad belt of morraines, kames, 

 dunes, and other modified deposits which reach in a huge, 

 irregular curve from Nova Scotia and the southern part of the 

 New England States to the prairies of the Canadian Northwest.
