PREFACE ix 



and insufficient descriptions, and faulty judgments have been perpetuated front) author 

 to author through long series of years. All these matters must be worked out in years 

 to come, when the horticultural plants in the various groups shall have been systemati- 

 cally studied with care. The Editor repeats the hope expressed in the preface written 

 fourteen years ago "that every entry in this book will be worked over and 

 improved within the next quarter century." 



Many persons aside from the leading authors have contributed to the enterprise in 

 the most helpful spirit. The Editor's daughter has borne much of the burden of the 

 office and editorial detail. Gardeners, fruit-growers, florists, vegetable-growers, teachers 

 and experimenters, botanists, and the printers, have responded with good fellowship 

 and with something like patriotic pride. Their names will be recorded in the concluding 

 volume; and the public that uses the book will reward them with its gratitude. 



Nor should the institutions that have afforded all these persons the opportunities to 

 make their contributions be overlooked. Aside from those agencies already mentioned, 

 the Cyclopedia is under special obligation for the use directly or indirectly of books and 

 collections to Cornell University, the United States Department of Agriculture, the 

 New York Botanical Garden, the Brooklyn Botanic Garden, the Missouri Botanical 

 Garden, the Gray Herbarium, the Royal Botanic Gardens, Kew, the agricultural 

 colleges and experiment stations, and others, Seed merchants, nurserymen, and other 

 commercial establishments of standing, have been very ready with suggestions and help. 



Many new illustrations have been added, representing the work of several artists. 

 Most of the new work has been made by B. F. Williamson, New York City; F. Schuyler 

 Mathews, Cambridge, Mass.; Miss M. E. Eaton, of the New York Botanical Garden; 

 Mrs. M. W. Gill, Washington; C. H. L. Gebfert, Boston; and Miss Matilda Smith, of the 

 Royal Botanic Gardens, Kew, England, whose initials will be recognized on the pfetSJ 

 of the famous Botanical Magazine. By permission of Professor Sargent, much of the 

 accm^ate and beautiful work of C. E. Faxon and others in Garden and Forest, a journal 

 that was discontinued more than fifteen years ago and is now out of the market, has been 

 adapted and made available for the present reader; record is made in the text of the 

 pictures of species, at the places where they are used. Some of the work in the old govern^ 

 ment surveys of the great West has also been brought to the use of the general public. 



It is not wholly with satisfaction that one puts forth a work oHhismagnitude. The 

 responsibility increases with the largeness of the enterprise, foi^^BH|^ro»«iot readily 

 purchase new and corrected editions of a work of this extent. E\-ery caj'g has been 

 taken to present an accurate and faithful account, and this is as far as the re'teponsibility 

 can extend. The Editor can not expect to make another cyclopedia of horticulture; 

 but he hopes that these six volumes will comprise another step in the collecting, assort- 

 ing and appraising of our horticultural knowledge.
