It is astonishing how many farmers buy instead of raising their
vegetables for the table, as well as feed for their stock.

Texas, for instance, has purchased $200,000,000 worth of food
products yearly from northern markets which might have been
produced more cheaply at home. It takes 15 to 20 acres of land in
Texas to grow cotton enough to buy 160 bushels of canned sweet
potatoes, while one acre of Texas soil would produce the same
quantity, and uncanned. [Footnote: THRIFT, a monograph published
by the National Education Association, 1918.]

Such topics as the following should be studied, consulting
