SOME information on the work of the Canadian Arctic Expedition additional to that alreadv published appears in the Geographical Review for October (vol. iv., No. 4). The whole of the coast-line from Cape Bathurst to the eastern end of Coronation Gulf, except Cape Parry peninsula, was surveyed on a scale of ten miles to an inch. The surveys were extended to include Croker River and Rae River. Other surveys included much of the Mackenzie delta. The most important geological research of the southern party, with whose work this paper bv Mr. R. M. Anderson deals, was the investigation of the copper-bearing rocks in the region of Bathurst Inlet. They occur on Banks Peninsula and most of the islands to the north of it. Though the ore so far discovered is of low grade, Dr. O'Neill, the geologist of the expedition, estimated the amount of ore at more than two billion tons, and believes that it can be profitably utilised. Water transport round Alaska would be long and uncertain, but a short railway to Great Bear Lake would probably solve the difficulty of export. The article is illustrated with two sketch maps and a number of valuable photographs.
