journals, to many dealers, who have been uniform in their 

 courtesy, and incidentally to Mr. Morris K. Jesup, whose mag- 

 nificent collection of woods at the New York Museum of Natural 

 History has been available to the writer as to others. These, 

 with other sources of information acknowledged by the writer, 

 and suggested to others, are suitably arranged in the following 

 list. Of the 148 illustrations, 138 are original, the drawings 

 having been prepared under the supervision of the writer from 

 actual specimens by Mr. Irving T. Worthley of Cornell Uni- 

 versity and several students of New York University, and the 

 photographs by Mr. John Hopfengartner, Jr., of Westchester, 

 New York City. Other illustrations are, so far as possible, 

 acknowledged in place. 



PREFACE TO THE SECOND EDITION. 



THE present book is far more complete and therefore more 

 useful than the earlier one. The form or arrangement that 

 found favor in the original edition has been retained; but 

 corrections have been made, and some sections have 'been 

 rewritten throughout. Over four hundred new names have 

 been added to the index.
