CANADA 485 The following figures indicate the nature of the progress made in wheat cultivation by this region within recent years. CANADA. THE WINNIPEG BASIN. [ Area ; Production '.

It is generally admitted that the present production of the land could be greatly increased, but with regard to its potential resources there is much difference of opinion. Over twenty years ago several estimates of the future production of wheat in the Winnipeg Basin were made by competent authorities, and they varied in amount from 250,000,000 bushels annually to 800,000,000 bushels. All such estimates,, however, must, from the very nature of the case, be extremely hypothetical in character, and for their fulfilment must depend not only upon the potential re- sources of the country, but upon the extent to which its demands are met. With regard to the first of these, it would appear .unlikely that the average yield for the five years 1927-31 (about 392,000,000 bushels) could be doubled. A recent authority1 has calculated that half of the potentially arable area in the Prairie Provinces is already cultivated, and that practically all the best land and most of the good land is now utilized. Of what is left, much lies in regions climatically more suitable for mixed farming than for wheat growing. 1 O. E. Baker in Economic Geography, Vol. iv, p. 416.
