What started him upon this crazy journey through the wilderness? Whatever it was, it would be worth while to isolate the germ and with it inoculate our present-day soil wasters. But he was not the first one of his kind. Hundreds of pre-historic planters had gone before him. For years, now, explorers have been searching out and sending back to America certain valuable discoveries. Tremendously interesting, all of them. As one reads, it becomes increasingly evident that a considerable amount of scientific plant and animal breeding, selection, perhaps even grafting and artificial cross fertilization, budding and slip propagating may have been practiced by pre-historic, intelligent, forgotten men long before our modern times. We usually find, today, that the best plants and animals have had their start in some center of old civilization. China, Manchuria, Japan, Indo-China, India, Persia, Asia Minor, Central America, Oceania--these places, the nurseries of all existing races of men are today the bonanza spots for these explorers. Such a coincidence could hardly have been due to chance. It must surely occur to the mind of anyone who cares to put two and two together that, in each of these centers, other ancient gatherers and planters had been busy in their day, just as our own explorers and experiment station scientists are carrying on today--our modern, scientific Johnny Appleseeds. It is hardly possible, here, to follow to the ends of the earth all of the trails of the tribe of Johnny Appleseed. One little section will do well enough for purposes of illustration. Let us consider Iran, or, as our fathers knew it, Persia. Here is a field that, possibly because of previous plunderings, is not now the most fruitful of our sources of plant and animal discovery, yet it is an eye-opener, and will do very well as a type of similar test-plots throughout the world. Here is a short list of only a few of the plants which have been developed for centuries, and were reported in the last century as growing in Persia--many, no doubt, descended from stocks which once grew in the famous hanging gardens of Babylon: apples, pears, filberts muskmelons, watermelons, grapes, peaches, plums, nectarines. And of flowers, these: marigold, chrysanthemum, hollyhock, narcissus, tulip, tuberose, aster, wallflower, dalia, white lily, hyacinth, violet, larkspur, pink and finally, the famous rose of Persia, from whence comes the attar of roses for which Persia is still famous. It would seem that someone must have possessed a knowledge of plant propagation in Persia centuries ago.
