Corn is one of the best plants to experiment with. Gather for planting only the full- est ears and those with the largest kernels. You must also select from the plants those that produce the most ears. Plant such corn grains, carefully se- lected, in a plot by themselves in the garden, and compare their yield with that of the non-selected corn. The accompanying picture shows what can be done by selection. We find that, by what is known as a law of heredity, like produces like; hence the grow^th in the case of the selected grains. Not only does the corn produce ears with a greater number of grains, but it may improve upon the quality of the a Improvement of com by selection; a, original type; h, improved type developed from it.
