It is pertinent to inquire, now, as to what types of pears the ancients had. Such an inquiry leads up to another and much more important question: Have new characters appeared in pears since Pliny wrote? If so, it may be possible that we shall be forced to assume that man's dominancy over this fruit has produced the new characters, in which case search might be made for the key to unlock more new characters. For the present, however, only the first question can be considered, before going into which it is necessary to know what the most prominent characters of the pear are. Only those of the fruit need be named. There are twenty outstanding characters which differentiate the varieties of pears now cultivated, not taking account of those introduced by the hybridization of _P. communis_ with _P. serotina_ which has given pomology the Kieffer-like varieties. These characters are: Smooth or russet skin; red, yellow, or green color; large or small size; early or late season; long or short stem; round, oblate, ovate, and pyriform shapes; granular, buttery, or breaking flesh; sweet or acid flavor. In the pears described by Pliny so many of these characters are mentioned or may be assumed to be present from inference, that the conclusion is forced that in the many new pure-bred pears of _P. communis_ which have come into existence since Pliny's time, showing a great shuffling of characters in pear-breeding, it is doubtful whether new characters have come into being in 2000 years. This, in turn, forces the conclusion that if this fruit is to be greatly changed, the change must come about through hybridization with other species. Another quotation from Pliny shows that the Romans valued pears as a medicine as well as a food, had curious notions as to their digestibility, and, as with most plants, ascribed other marvelous qualities to them. Thus, Pliny says: "All kinds of pears, as an aliment, are indigestible, to persons in robust health, even; but to invalids they are forbidden as rigidly as wine. Boiled, however, they are remarkably agreeable and wholesome, those of the Crustumium in particular. All kinds of pears, too, boiled with honey, are wholesome to the stomach. Cataplasms of a resolvent nature are made with pears, and a decoction of them is used to disperse indurations. They are efficacious, also, in cases of poisoning by mushrooms and fungi, as much by reason of their heaviness, as by the neutralizing effects of their juice. "The wild pear ripens but very slowly. Cut in slices and hung in the air to dry, it arrests looseness of the bowels, an effect which is equally produced by a decoction of it taken in drink; in which case the leaves are also boiled up together with the fruit. The ashes of pear-tree wood are even more efficacious as an antidote to the poison of fungi.
