The case is not so simple, however, as this brief statement would make it appear. There are many kinds of Paradise stock, as also of Doucin. If one were to bring together living plants of all the kinds of natural dwarfs and semi-dwarfs that could be found in nurseries and growing collections, one would undoubtedly find a nearly complete series, so far as stature of tree is concerned, from the very dwarf to the full-sized standard tree. To say that a person is growing grafted dwarf apple-trees does not signify how large the trees may be expected to grow, for one may not know the particular kind of stocks on which the variety is grafted. In fact, it is considered even in Europe, where dwarf apples are chiefly grown, that the proper identification of dwarf stocks is still a subject for careful investigation. When the Paradise dwarfs first came into existence is undetermined. They appear to have been known in the Middle Ages. The many races, as the Dutch, French, Metz, Nonsuch, Broad-leaved, indicate an ancient origin. We cannot be too certain what apple-trees were meant in the early references to the Paradise apple. The fruits of the present natural Paradise apple-trees are not sufficiently attractive to justify us in considering them the "Tree of Paradise" or apple of the Garden of Eden, which circumstance is supposed by some to account for the name. "Paradise" was originally a park or pleasure ground, applied also to the Garden of Eden, and later to horticultural gardens. John Parkinson wrote his great treatise on horticulture, 1629, under the title, "Paradisi in Sole Paradisus terrestris; or, a Choice Garden of all Sorts of Rarest Flowers, etc." Now we use the word for gardens of bliss. The word Doucin, from the Italian, is supposed originally to have designated apples of sweet flavor, but it now applies technically to a class or race of semi-dwarf apple-trees. For the purpose of this little book, however, the interest in the dwarf apple centers not so much in the origin of the stock as in the natural-history of the tree itself and the good skill of hand and heart that one may expend in the growing of it. If one would come close to a plant, knowing it intimately in every season, causing it to respond to sympathetic treatment through a series of years, then a garden collection of dwarf apples may satisfy the desire. It is too bad that we do not have time to cultivate the dwarfs often in the yards and gardens of North America. We are more familiar with the raising of dwarf pears (which are grafted on quince stocks since there is no similar race of natural dwarf pear-tree), but we do not give them the thumb-and-finger care that is demanded for the choicest results. The abundance of apples in the market should only stimulate the desire of the connoisseur to have trees and fruits that are wholly personal. The market produce can never gratify the affections.
