"The main sources of overseas supply are too well known to require recapitulation here. The imports from the Dominions and India and their proportionate contribution to the United Kingdom's total imports and wheat requirements since 1901 have been as follows: 1901-5 Percentage From Annual Total Total average imports requirements Million Per Per cwts cent cent Canada 10.3 9.2 7.4 Australia 6.6 5.9 4.8 New Zealand .4 .4 .3 India 15.5 13.9 11.2 32.8 29.4 23.7 1906-10 Percentage From Annual Total Total average imports requirements Million Per Per cwts cent cent Canada 17.2 15.1 12.0 Australia 9.4 8.2 6.6 New Zealand .3 .3 .2 India 13.3 11.7 9.3 32.8 29.4 23.7 1911-13 Percentage From Annual Total Total average imports requirements Million Per Per cwts cent cent Canada 24.5 20.5 16.4 Australia 12.6 10.6 8.4 New Zealand .4 .3 .3 India 21.5 18.0 14.4 59.0 49.4 39.5 "The large increase in the proportion received from the Dominions is, of course, mainly due to the great extension of wheat cultivation in Western Canada since the beginning of the century." [84] _Future Supplies_ "As the United Kingdom is dependent for so large a proportion of its wheat supplies on the surplus of oversea countries, it is of material interest to examine whether this surplus is increasing, or whether the growth of population is proceeding more rapidly than the extension of the wheat-growing area. "The Board of Agriculture and Fisheries in 1912 estimated [85] that the extension of the wheat area and the growth of population during the period 1901-1911 was as follows: Wheat area Percent Population.
