Revised edition. "Home production of supplies offers the Southern farm family an easy way to reduce the cost of living. Because of the long growing season, and the short, mild winters of the Cotton Belt, garden vegetables may be grown there in abundance throughout the year with little labor and at trifling expense. Necessary livestock products and feeds for farm animals can be produced on the farm much more cheaply than they can be bought. This bulletin suggests ways in which southern farmers may make the most of opportunities for the home production of commodities that otherwise would necessitate cash outlay." -- p. 2
