An essay by Prof. Beal. This is another of those little pieces of excellent work which Prof. Beal is continually performing. One might read a heavy volume on corn, and not learn more than is taught here. A point which interested us very much in this paper is that though the effects of crossing will often be shown in the grain of the same season, it is not always so. Sometimes the characteristics of the male parent do not appear in the seed till the succeeding generation. This is a very important fact which Prof. Beal should have the full credit of discovering. Even the fate of a lawsuit might hang on such knowledge.
