Commercial grape-growing is now a great industry in America, and deserves a treatise or its own. But there are also many demands for information on grape-growing by those who grow fruits for pleasure, especially by those who are escaping from cities to suburban homes, for the grape is a favorite fruit of the amateur. And so, though Pleasure and Profit are a hard team to drive together, this manual is written for both commercial and amateur grape-growers. In particular, the needs of the amateur are recognized in the chapter on varieties, where many sorts are described which have little or no commercial value. No other fruit offers the enchantment of novelty to be found in the grape. Alluring flavors, sizes, and colors abound, of which the amateur wants samples. The commercial grower who plants but one variety often finds himself dissatisfied with the humdrum of the business. He should emulate the amateur and plant more kinds, if only for pleasure, remembering the adage, "No profit grows where is no pleasure ta'en." Greater pleasure in grape-growing, then, is offered as the justification of the long chapter on varieties. At the risk of too broad spreading, the author discusses, in a book mainly devoted to native grapes, the culture of European grapes in the far West. The chief aim is, of course, to set forth information that will be helpful to growers of these grapes in the western states, there being no treatises to which western growers can refer, other than bulletins from state and national agricultural institutions. There is, however, another reason for attempting to cover the whole field of grape-growing in America. It is certain that eastern grape-growers will sometime grow European grapes. Western vineyards might well be enlarged with plantings of native grapes. On the supposition, then, that the culture of both European and native grapes is to become less and less restricted in America, the author has ventured to discuss the culture of all grapes for all parts of North America. In the preparation of this manual, the author's "The Grapes of New York," a book long out of print and never widely distributed, has been laid under heavy contribution, especially in the description of varieties. Acknowledgments are due to F. Z. Hartzell for reading the chapter on Grape Pests and their Control and for furnishing most of the photographs used in making illustrations of insects and fungi; to F. E. Gladwin for similar help in preparing the two chapters on pruning and training the grape in eastern America; to Frederic T. Bioletti for permission to republish from a bulletin written by him from the Agricultural Experiment Station of California almost the whole chapter on Grape Pruning on the Pacific Slope; and to O. M. Taylor and to R. D. Anthony for very material assistance in reading the manuscript and proofs. U. P. HEDRICK. GENEVA, N. Y., Jan. 1, 1919. TABLE OF CONTENTS
