inorganic salt mixture and butter fat produced only about onethird to two-thirds of normal growth. Bread made from a mixture of 25 parts of peanut flour and 75 parts of wheat flour furnished adequate proteins and water-soluble vitamine for normal growth. A similar bread containing 15 parts of peanut flour and 85 parts of wheat flour contained proteins and sufficient water-soluble vitamine for growth at very nearly the normal rate.

Sweet potatoes of this grade are often alternated with cotton in the South in order to check the boll-weevil, and this will give a considerable supply of raw material.
