The Food Administrator asks us to eat corn bread and save the wheat for export. It is a very small sacrifice to eat corn bread at one meal or more a day. Indian corn saved our New England ancestors from starvation, and we can in part substitute it for our wheat and send the latter abroad to spare others from starvation. The simplest elements of patriotism demand that we do this. Therefore let us cry, "Eat corn bread and save the wheat for France, the home of Lafayette!" The United States Department of Agriculture has estimated that only 6.6 per cent. of our corn crop is used for human food, and of this, 3.4 per cent. is consumed by the farmers and their families. The substitution of foods is no new thing. We find that an English contemporary author thus described the food habits of the English people during the "golden days of Good Queen Bess," three hundred and fifty years ago: "The gentilitie commonly provide themselves sufficiently of wheat for their own tables, whylest their household and poore neighbours in some shires are forced to content themselves with rye or barleie; yea and in time of dearth many with bread made eyther of beanes, peason[1] or otes, or of altogether and some acornes among." [1] An obsolete plural of pease. A difference between those days and ours is that the "gentilitie" and the "poore neighbours" are now asked to unite in reducing the consumption of wheat and to do this for the safety and welfare of all mankind. Another point in war economy is the use of whole milk in greater quantity, and the diminution of the use of butter and cream. Cream is bought only by the wealthy, but in sufficient volume to largely reduce the amount of whole milk available. In Germany before the war 15 per cent. of the milk supply of that country was used for the production of cream. The consequent restriction of the milk supply was distinctly to the detriment of the health of the peasant farmers of Bavaria. Regarding the use of butter, a Swiss professor, himself an expert in nutrition, complains that whereas in his youth children were never given butter on their bread for breakfast, not even when there was no jam in the house, yet to-day absence of butter from the table is held to be indicative of direst poverty. If one takes a pint of whole milk daily, or even, as we have seen, cabbage or beet-tops in its stead, one may take fat in the forms of olive oil or cottonseed oil, corn oil, cocoanut oil, peanut butter, or in other vegetable oils, without possible prejudice to health. Osborne and Mendel, and more recently Halliburton, have pointed out that oleomargarine as prepared from beef-fat contains the fat-soluble growth-promoting accessory substance or vitamine which is present in butter-fat, but which is not contained in vegetable oils or in lard. Halliburton and Drummond summarize the practical results of their work as follows:
