Abstract
THE first volume of a work which describes the observations carried out by the Canadian Polar Year Expeditions, 1932-33, is largely statistical; but there is a general introduction by Dr. J. Patterson, the director of the Canadian Meteorological Service, and notes on the instruments at the Expeditions' four stations-Cape Hope's Advance, Chesterfield Inlet, Coppermine and Meanook, together with maps and photographs (Dominion of Canada: Department of Transport, Air Services Branch, Division of Meteorological Services of Canada. Canadian Polar Year Expeditions, 1932-33, Meteorology: Cape Hope's Advance, Chesterfield Inlet, Coppermine, Meanook. Vol. 1. Pp. xvi-f-443 + 46 plates. Ottawa: King's Printer, 1940). Meanook (Alberta) is a permanent magnetic station-the nearest to the north magnetic pole-the other three stations were temporarily set up for this undertaking. The statistical matter which, as has already been mentioned, occupies a very large proportion of the volume, consists mainly of hourly values of atmospheric pressure, temperature, humidity, precipitation, sunshine and wind velocity, to which are added full particulars of the upper winds revealed by numerous observations with pilot balloons, and notes on optical phenomena. The period covered-August 1932-September 1933-is long enough to illustrate the inhospitable climate of these regions, with frequent gales and strong winds, and a long and severe winter. The complete absence of trees, and even of bushes, worthy of the name, at the more northerly stations needs no other explanation.
