food, drink and medicinal purposes. An oil used in making perfumes for scenting soaps and confectionery is also extracted from the seeds of the Mahaleb because of which use this species is often called the "Perfumed Cherry."

In the old herbals and pomologies much is made of the value of cherries for medicinal purposes. The fruit was supposed to be a sovereign remedy for various ailments of the digestive tract as well as for nervous disorders and epilepsy. The astringent leaves and bark, or extracts from them, were much used by the ancients in medicine and are still more or less employed both as home remedies and in the practice of medicine as mild tonics and sedatives. One of the active chemicals of the leaf, seed and bark is hydrocyanic acid to which is largely due the peculiar odor of these structures. A gum is secreted from the trunks of cherry trees, known in commerce as cerasin, which has some use in medicine and in various trades as well, especially as a substitute and as an adulterant of gum arabic.

At least three cultivated cherry trees produce wood of considerable value. The wood of the cherry is hard, close-grained, solid, durable, a handsome pale red, or brown tinged with red. Prunus avium, the Sweet Cherry, furnishes a wood which, if sufficient care be taken to season it, is of much value in cabinet-making and for the manufacture of musical instruments. Prunus mahaleb is a much smaller tree than the former but its wood, as much as there is of it, is even more valuable, being very hard and fragrant and dark enough in color to take on a beautiful mahogany-like polish. In France the wood of the Mahaleb cherry is held in high esteem, under the name Bois de St. Lucie, in cabinet-making and for toys, canes, handles and especially for the making of tobacco pipes. In Japan the wood of Prunus pseudocerasus is said to be in great demand for engraving and in making the blocks used in printing cloth and wall-paper. In America the wood of the orchard species of cherries is seldom used for domestic purposes, that of the wild species being so much more cheaply obtainable and serving all purposes quite as well.

To people who know it only for its fruit, the cherry does not appear particularly desirable as an ornamental. But wild and cultivated cherries furnish many beautiful trees in a genus peculiar for the beauty of its species. The color and abundance of the flowers, fruits and leaves of the cultivated cherries and the fact that they are prolific of forms with double flowers, weeping, fastigiate or other ornamental habits, make the several species of this plant valuable as ornamentals. Besides, they are vigorous and rapid in growth, hardy, easy of culture, comparatively free from pests and adapted to a great diversity of soils and climates. Both the ornamental and the edible cherries are very beautiful in spring when abundantly covered with flowers, which usually open with the unfolding leaves, as well as throughout the summer when overspread with lustrous green foliage and most of them are quite as conspicuously beautiful in the autumn when the leaves turn from green to light and dark tints of red. All will agree that a cherry tree in full fruit is a most beautiful object. In the winter when the leaves have fallen, some of the trees, especially of the ornamental varieties, are very graceful and beautiful, others are often picturesque, and even the somewhat stiff and formal Sweet Cherries are attractive plants in the garden or along the roadside.

Very acceptable jellies, sauces and preserves are made from several of the wild cherries in the Padus group. The peasantry of the Eastern Hemisphere have in times of need found them important foods as have also the American Indians at all times. The fruits of some of the species of Padus are quite commonly used in flavoring liqueurs and on both continents are sometimes fermented and distilled into a liqueur similar to kirschwasser. The bark of different parts of the trees of this group is valuable in medicine—at least is largely used. The trees of several species form handsome ornamentals and some of them are in commerce for the purpose. Prunus serotina, one of the group, because of the strength of its wood and the beautiful satiny polish which its surface is capable of receiving, is a valuable timber tree of American forests. For the products of the members of this group, as just set forth, the domestication of some of the species of Padus might well be pushed.

LITERATURE OF THE CHERRY

Despite the important part they have played in orcharding since the domestication of fruits in temperate zones, as shown by their history and their present popularity, pomological writers have singularly neglected cherries. There are relatively few European books devoted to them and in America, while there are treatises on all others of the common tree-fruits, the cherry alone seems not to have inspired some pomologist to print a book. Neither are the discussions in general pomologies as full and accurate as for other fruits. The reason for this neglect is that the cherry, until the last decade or two, has scarcely been a fruit of commerce, having been grown almost entirely for home use or at most for the local market. As a result of this neglect of the cherry by students of pomology, we have no authoritative nor serviceable system of classification of the varieties of cherries and the nomenclature of this fruit is in an appalling state of confusion, as a glance at the synonymy of some of the older varieties discussed in The Cherries of New York will show.

AMELIORATION OF THE CHERRY

The amelioration of the cherry has been in progress almost since the dawn of civilization, yet few men have directed their efforts toward the improvement of this fruit. The histories of the varieties described in The Cherries of New York show that nearly all of them have come from chance seedlings. Possibly there has been little interest in improving cherries because this fruit is comparatively immutable in its characters.

In spite of the fact that there are a great number of varieties, 1,145 being described in The Cherries of New York, this of all stone-fruits is most fixed in its characters. The differences between tree and fruit in the many varieties are less marked than in the other fruits of Prunus and the varieties come more nearly true to seed. Though probably domesticated as long ago as any other of the tree-fruits, the cherry is now most of all like its wild progenitors. The plum is very closely related to the cherry but it has varied in nature and under cultivation much more than the cherry and in accordance with different environments has developed more marked differences in its species to endure the conditions brought about by the topographical and climatic changes through which the earth has passed. Under domestication more than twice as many orchard varieties of the plum have come into being as of the cherry. In spite of this stability, there are ample rewards in breeding cherries to those who will put in practice rightly directed efforts to improve this fruit—a statement substantiated by the histories of some of the best varieties, described later in this text, which were originated through what was passing as current coin in plant-breeding before the far better methods of the present time, brought about by Mendel's discovery, came into being.

The cherry, as the histories of its many diverse kinds show, has been improved only through new varieties. There is no evidence, whatever, to show that any one of the several hundred cherries described in this text has been improved by selection as a cumulative process, or, on the other hand, that any one of them has cumulatively degenerated.
