Abstract
THE fact that the second edition of Oil and Gas in Western Canada by G. S. Hume (Canada, Dept. Mines, Econ. Geol, Ser. 5, 1933) contains twice as many pages as the first is an indication of the mass of new data of oil and gas prospects in western Canada acquired during the last five years. The author has wisely refrained from amplifying to any marked extent the brief introductory chapter on oil origin and accumulation, but the additional illustrations of various types of structures certainly make his digest more palatable both to the uninitiated and to those familiar with the subject. In view of the rapid advancement of geophysical science and its now widespread application, the chapter on this subject is still too brief and sketchy to be of real technical value. In the first edition, a chapter was devoted to a survey of carbon ratios in relation to known occurrences of oil and gas, emphasis being laid on the fact that favourable structures can be determined by means of these ratios it is therefore significant that this section has been omitted in the second edition. The additional information given is wholly relevant to the main issue, and serves as a useful basis of comprehension of the actual descriptions of oil and gas fields. Order and proportion are given to these descriptions, and valuable technical data contained therein made more accessible by division of the region under review into seven districts, namely, the Foothills, Southern, Central, and Northern Plains of Alberta, the Plains of Manitoba and Saskatchewan, Northwest Territories, and British Columbia. Lack of an index, however, to such a large volume is a decided disadvantage.
