The honeybee, above, is emerging from Pima S-1 cotton flower. As it dips into the flowers of other cotton plants in search of nectar it will cross-pollinate those plants. Although cotton is a self-pollinating plant, bee culture scientists of the U. S. Agricultural Research Service are finding in tests at Tucson, Arizona, that cross-pollination with bees increases cotton yields.—U.S.D.A. photo by Forsythe.
