Several of these products have had their influence upon the history and poetry of the world. It will be remembered by most high school students that when the Caesars and big shots of Rome and Greece wished to create a big splash in the social ponds of their day, they sent, at enormous expense, for melons and dates from Persia. Melons, in particular, seemed to be the high spot in those Lucullan feasts, and, in this connection it is well to remember that Lucullus, himself, as commanding general of a Roman legion, had long lived in Persia and had, no doubt, acquired a taste for Persian delicacies. His princely estates near Rome, no doubt, grew rare plants from Asia Minor and were very likely tended by the skilled Aryan, early Accadian or Semitic gardeners of Persia. These slaves were probably descended from and were heir to the trade secrets of some of the very builders of that seventh wonder of the world, the hanging gardens of Babylon. Except for those forgotten workers from Persia, one may well wonder whether, today, our Rocky Ford, Ohio Sugar, or Hearts-of-Gold muskmelon delicacies would exist at all. An interesting side-light may be found in the history of the peach. Originally this fruit was in all probability a poisonous variety of almond. What wizard, or succession of wizards, was it who created a peach from a pest--an asset from a liability? Persian, probably. Whoever did it, it constitutes one of the outstanding miracles of plant breeding, whether natural or artificial. The poison was sealed within the seed (where it remains to this day) and the nectar of the gods was bred into the pulp around it. Consider also the Persian walnut, now, for some strange reason, popularly called "English" walnut. This delicacy, too, was unlikely to have happened merely by chance. It was, no doubt, bred by a race of men trained in observation and experiment such as the Persians preeminently were. Having first been nomads, domesticators and breeders of animals; they eventually became husbandmen, breeders of trees and plants, and they undoubtedly found that the principles which were so usefully employed in producing animal variations could also be used in producing and fixing plant varieties. The pollen or germ of an outstanding good male individual, when brought into contact with the pistil or ovum of an outstanding female individual of the same species will produce a scion that is more likely than any other to have good qualities. Here was the secret of most of the progress which has been made in both animal and plant breeding, a secret of immense value--so valuable, in fact, that it was guarded for generation after generation by a close-mouthed priesthood.
