Some of the 400 Come to Judgment
This picture shows a few of the several hundred varieties of cherries plucked on the same day from the same tree, and laid out for Mr. Burbank's examination and selection. As new combinations are effected each season through cross-pollentration, there are always unique varieties to be found on the tree each June-time, and these new varieties, may, of course, be perpetuated by grafting.
