Another point of interest is that a number of the internodes are alternately fjrooved or flattened. Those persons who have made a 'corn-stalk tiddle' will remember that it was this peculiar flattening, which accommodates the ears, that rendered possible the manufacture of the crude musical instrument. The sap bundles of the corn stem are isolated and of the closed collateral tyye. Leaves.—The leaves of corn are two-ranked; that is, they alternate on opposite sides of the stems. Each leaf may be divided into three parts,—a sheath, which is open along one side, a ligule, or keep the leaf-blade perfectly flat. In hot, dry weather, water is lost from these cells and the leaf-blade rolls up and thus protects itself against Fig. 600. High northern corn.

The ligule has been appropriately called the rainguard, as it acts in such a way that rain- water with dust particles held in .solution, which runs down the grooved surface of the leaf, runs off on either side on reach- ing the ligule and does not run into the space between the stem and sheathing base, where dirt might other- wise easily accumulate. The folds in the margin and base of the leaf, which are formed because the edge grows more rapidly than the middle, are in- genious natural or mechanical contri- vances to ease the strain on the leaf- blade when the wind blows.
