Peach and Almond Stones Compared
This illustration shows the similarity between the stones of the peach and the almond, at the same time revealing the characteristic differences. Some horticulturists believe that the almond was the original stock from which the peach was developed through selective breeding in prehistoric times. Others do not accept this theory, but all are agreed that peach and almond are pretty closely related, and at least have common ancestors. Mr. Burbank made interesting experiments in hybridzing the almond and the peach which are fully described in another volume.
