A History of the Canadian Pacific Railway. By Harold A.
Innis. (P. S. King. 12s. 6d. net.) Dr. Innis, of Toronto University, has produced a valuable study of the C.P.R. in its political and economic aspects. Its history, as he says, is " the history of the spread of Western civilization over the northern half of the North American continent." But for the railway, the prairie provinces could not have been settled or able to feed the mother-country, and the Dominion would be a very unstable federation. The author has much to say about the incessant complaints of the Western farmers against high railway rates and suggests that in the circumstances the rates cannot well be reduced, unless, indeed, Eastern Canada is unexpectedly willing to tax itself for the benefit of the West. This is, of course, a leading issue in Dominion politics.
