It is fair to add that a very large part remains unsurveyed and unprospected. Canada's Fertile Northland. Evidence heard before a Select Committee of the Senate of Canada, 1906–7. Edited by Captain E. J. Chambers. Pp. 140; with illustrations and a volume of maps. (Ottawa: Government Printing Bureau, 1908.)
