POTATOES DO NOT MIX IN HILLS. "SUBSCRIBER," Piper City, Ill., wishes to know if potatoes mix when planted side by side, or even in the same hill, or whether they remain distinct varieties. They will not mix when so planted. The potato planted is not a seed, but is a thickened underground stem. The eyes are small sunken buds. These eyes send up shoots and thus continue the variety. Roses, black- berries, lilacs, peppermint and great numbers of other plants multiply themselves by underground stems, in a manner similar to the potato. So willows, grapes, currants and gooseberries are multiplied by cuttings from stems above ground. The sprouts from apple or cherry trees will be of the same variety as the main trees, unless the sprout came from a root into which the main trunk was once engrafted. Now, varieties of potatoes are obtained by planting the seeds from the little balls which grow on the tops of the vines. So we get new varieties of peaches, apples, cherries, &o, by planting their seeds. W.J. B.
