Note the low percentage of water ifi seeds as well as the similarity of content of the potato and the banana. _ beets contained less than 5 per cent of sugar; because of careful seed selection and intelligent fittiag of the environ- ment to the plants, the best quality of beets grown today con- tains as high as 22 per cent. The original potato tubers weighed about an ounce; potatoes weighing several pounds are now grown, and a plant may produce ten times as many tubers as are produced by the original plant. The testing of wild species of plants for possible cultiva- tion and use as sources of food, and the introduction of species cultivated in other countries, is being carried on by govern- ments in all parts of the world. Through its agricultural ex- plorers the United States has probably accompKshed more.
