In the Southern section we find a wastefulness similar to that in the corn belt, but due to wholly different causes. The communities are old-settled, but in many instances they are still abnormally depressed by the terrible effects of the great war, followed by a period of social and economic stagnation. Here there was little but agriculture for the people to rely upon, and their methods have, until recent years, been very backward. The growing of the same crops year after year upon the same fields, the neglect of precaution against the washing away of the soil surface, and the failure to use fertilisers, have made the profits of tillage disappointingly small. Billions of dollars have been lost by these communities through persistent soil exhaustion and erosion. In the last few years the Federal Department of Agriculture has maintained a most efficient staff of agricultural experts under the direction of Dr. Knapp, one of the ablest organisers of farm improvement I have ever met. The General Education Board, who administer large sums provided by Mr. Rockefeller, recognising the educational value of Dr. Knapp's operations, are contributing about one hundred thousand dollars a year to his work. Dr. Knapp and his field agents have no difficulty at all in demonstrating that the yield may be doubled, and the cost of production greatly reduced, merely by the application of the most elementary science to agriculture. I heard him tell of a farmer whom he had induced to allow his boy--still attending school--to cultivate one acre under his instructions. In the result the boy quadrupled the number of bushels of corn to the acre that his father, following the traditional methods, was able to raise. It would be easy to multiply such instances of thriftlessness and neglected opportunity, of poverty within easy reach of abundance, which have brought it about that the future of the nation is actually endangered by the failure of the food supply to keep pace with the increase of its still relatively sparse population.
