and to describe all the newer varieties from the best specimens obtainable, and these may not, in all cases, have been perfect. Under such circumstances, this work must necessarily be incomplete, and especially where the possessors of claimed-to-be new and valuable varieties have either refused or failed to give any information in regard to them. On the contrary, however, I must acknowledge my indebtedness to many correspondents, who have so generously placed specimens of both trees and nuts of rare new varieties in my hands for testing and describing, as well as assisting me in tracing their history and origin. That this treatise may become the pioneer of many other and better works on nut culture is the sincere wish of RIDGEWOOD, N. J., 1896. THE AUTHOR. LIST OF ILLUSTRATIONS. Page. 8.
