whom I have consciously copied. Such recognition will be 

 found in its appropriate place. I must not fail, however, to 

 recognize here the value of the services and courtesies ex- 

 tended to me by the Forest Service of the United States, 

 through its able dendrologist, Mr. George B. Sudworth, 

 and also to extend grateful acknowledgments for the use 

 of many of the photographs here shown, due credit being 

 given on each. I take great pleasure in expressing my grat- 

 ification at the approval and suggestions of Professor F. 

 W. Kane, State Forester of Massachusetts, to whom was 

 submitted the manuscript before it was placed in the hands 

 of the publishers. Professor Rane's approval is of moment, 

 as it comes from one of the most practical foresters in the 

 country.
