Yale University Press is to be congratulated upon two remarkable little books, each containing multum in parvo—Prof. Graham Lusk's, "The Fundamental Basis of Nutrition," and the little book now under review, Prof. L. B. Mendel's "Changes in the Food Supply and Their Relation to Nutrition."
Professor Mendel starts with Sir William Crookes' forecast made in 1898, to the effect that by 1931 we should have reached the limit of wheat production upon the earth, while the population would presumably be still increasing ; and this Sir William regarded as a most ominous prediction, as he regarded wheat as "the most sustaining food grain of the great Caucasian race." Professor Mendel agrees that this estimation as to wheat acreage is probably correct, but that in the first place the yield by acre would be increased and that, moreover, any alarm in relation to wheat acreage fails to take into consideration
