this character, on every phase of tree study. He presumes no further;
yet he hopes that by adhering to what is salient and by eliminating the
less important, though possibly interesting, facts, he is able to offer

In the preparation of Chapter VIII on "Our Common Woods: Their
Identification, Properties and Uses," considerable aid has been received
from Prof. Samuel J. Record, author of "Economic Woods of the United
States." Acknowledgment is also due to the U.S. Forest Service for the
photographs used in Figs. 18, 122 to 138 inclusive and 142; to Dr.
George B. Sudworth, Dendrologist of the U.S. Forest Service, for
checking up the nomenclature in the lists of trees under Chapter V; to
Dr. E.P. Felt, Entomologist of the State of New York, for suggestions in
the preparation of the section of the book relating to insects; to Dr.
W.A. Murrill, Assistant Director of the New York Botanical Gardens, for
Fig. 108; and to Mr. Hermann W. Merkel, Chief Forester of the New York
Zoological Park, for Figs. 26, 59 and 60.
