Abstract
CANADA, METEOROLOGICAL SERVICE (1907).—This report, which extends to xx+748 quarto pages, is considerably belated, owing probably to the immense amount of data included in this extensive system. It should be borne in mind, however, that the results for about 300 stations, with synopses of the weather, are published one month after date in the Monthly Weather Review, and also that a map is issued three days after the close of each month. The present volume is divided into seven parts, which may be summarised as (1) observations at ordinary stations of various classes, mostly taken at local time; (2) observations at telegraphic reporting stations, taken at 75th meridian time; and (3) magnetic observations made at Agincourt Observatory. The tables, with monthly and yearly means, are very complete, but in the absence of maps it is difficult to obtain a general view of the annual distribution of the different elements. The outstanding feature of the year was the exceedingly cold weather experienced in the western provinces in January. In some of these it was the coldest January on record, the mean temperature being 6–22° below the average. At some stations in Alberta minimum temperatures as low as 56° F. below zero were registered. (On January n, 1911, we note that a temperature of —76° was recorded at Fort Vermilion, Alberta.) The weather forecasts issued for all districts were very successful, the average of complete and partial success being 85·6 per cent.
