LYON COMPANY, STATE PRINTERS 1911 NEW YORK AGRICULTURAL EXPERIMENT STATION, GENEVA, N. Y., _December 31, 1910_. _To the Honorable Board of Control of the New York Agricultural Experiment Station_: GENTLEMEN:—I have the honor to transmit herewith Part II of the report of this institution for the year 1910, to be known as _The Plums of New York_. This constitutes the third in the series of fruit publications that is being prepared under your authority. The data embodied in the volume are the result of long-continued studies and observations at this institution as well as throughout the State, to which has been added a large amount of information that commercial plum-growers have very kindly furnished. The attempt has been made to produce a monograph including all the cultivated plums, and it is hoped that the result will be recognized as a worthy advance in the literature of this class of fruits. W. H. JORDAN, _Director._ PREFACE _The Plums of New York_ is the third monograph of the fruits of this region published by the New York Agricultural Experiment Station. The aims of these books have been stated in full in _The Grapes of New York_, but it is considered best to re-state some of these briefly and to indicate some features in which the book on plums differs from the one on grapes.
