Roots.—The roots of maize are of two kinds : (1) Those that are formed when the kernel germinates, which develop into the strong underground feed- ing roots ; (2) those that develop in a circle from the lower nodes of the stem, and serve primarily as prop or supporting roots. Before these adven- titious aerial roots reach the soil, they are covered by a copious mucilaginous material, which probably prevents dry air and dry winds injuring the important growing apex. Later these air roots absorb water ard plant-food from the soil into which they penetrate. Stem.—The stem of corn, known botanically as a culm, is divided into nodes (knots) and internodes (straight stem parts). The internodes differ from those of most gi-asses by being solid instead of hol- low. The basal part of each of the lower leaf sheaths is provided with a ring of soft tissue, which
