_The Cherries of New York_ contains an historical account of cultivated cherries, the botany of this fruit, a statement of its present economic status in America, descriptions of all known varieties of cherries, the synonymy and bibliography of the species and varieties, and biographical sketches of the persons who have contributed materially to cherry culture in America. The most important varieties are illustrated in colors. Everything that was thought would be helpful in breeding cherries has been included, and special search has been made for such material. So, too, whatever was thought to be of interest to students of ecology and of plant distribution has been added. In the monographs on grapes and plums it was necessary to devote much space to the botanical relationship of these fruits since each contains more than a score of species under cultivation, some of which are scarcely known and most of which are extremely variable. The botany of cultivated cherries is comparatively simple and has been made plain by botanical writers. Yet the contemplation of the several species from a horticultural standpoint adds something, we believe, to the botany of cherries, especially as concerns the forms of the Sweet Cherry and the Sour Cherry which have been variously treated by botanists. As compared with their congeners, especially the plums, the economic species of cherries are remarkably well delimited, showing far less responsiveness to environment and having seemingly less inherent variation, so that there need be little confusion in botanical classification. On the other hand varieties are so similar that it is only with the greatest difficulty that closely related sorts are distinguished and there is great confusion in the synonymy, the chief task of the present work being to distinguish the true names from the synonyms of the varieties described. In _The Cherries of New York_, as in the preceding fruit books from this Station, effort has been made to give as accurately as possible the region in which the species and varieties grow best and to set forth fully the local prejudices of the fruits. Such knowledge cannot but be of value in determining the factors which govern the distribution of plants. The establishment of community relationships and description of plant communities now constitute an important part of botany on the one side and of geography on the other. No phenomena give better expression of the climate and the soil of a region than plant communities. When monographs of several of the fruits of temperate North America shall have been completed, with statements of likes and dislikes of the fruits and their varieties as to climate and soil, material should be available to establish plant communities from which can be drawn valuable generalizations.
