Ancestor and Descendent
This picture shows the wonderful contrast in size between the original wild partially stoneless plum and Mr. Burbank's perfected stoneless prune. Many generation lie between the two, yet the essential character of stonelessness that gave the little plum value has been retained in the remote descendant, while the strains of numerous cultivated plums have been bred in, so that the offspring of the dwarf plum is now large in size and of fine quality of flesh.
