is preferred to make a general acknowledgment of the important assistance derived from many pomological authors of our own country and of Europe. Quotations are credited on the pages where they occur.

But the writer is also under great obligations to a host of co-laborers for the assistance they have kindly rendered him in the collecting, and in the examination and identification of fruits. Such friends he has happily found wherever he has turned in the pursuit of these investigations, and there are others whom it has never been his good fortune to meet face to face. To name them all would be impossible. The contemplation of their favors sadly recalls memories of the departed, but it also revives pleasant associations of the bright spirits that are still usefully engaged in the numerous pomological and horticultural associations of our country, which have become important agencies in the diffusion of valuable information in this branch of study.

To all of his kind friends the author returns his sincere thanks.

With a feeling of hesitation in coming before the public, but satisfied that he has made a contribution to the fund of human knowledge, this volume is presented to the Horticulturists of our country, for whom it was prepared by their friend and fellow-laborer,
