Selection to modify certain characters of the plant,'even though yield is not affected, is often justified. For example, in the SoUth many varieties of corn have a tendency to bear the ears quite high on the stalk and in an upright position. Although neither of these characters ma- terially affects yield, seed should be selected with the idea of cor- recting these defects, as in the one case ease of harvesting is facilitated and in the other the quality of the grain is improved, from the fact that a drooping ear sheds water bet-.
