PREFATORY NOTE 



The author expresses gratitude t<> all those who have extended courtesies during 

 the preparation of thisLeaflet. Especially are thanks due to the Honorable Gifford 

 Pinchot, President of the National Conservation Association and to Professor J. H. 

 Tourney, Director of the Yale Forest School, who as members of the Appointive 

 Committee on Woods and Forestry of the American Museum read the Leaflet in 

 proof and gave valuable suggestions; also to the United States Forest Service and 

 Doubleday, Page and Company, who allowed the use of photographs for many of 

 the half-tones. Primarily, of course, indebtedness is due to the Forest Service, 

 since much of the subject matter concerning practical pomts has been compiled 

 from its work. 



The pamphlet has been made to cover a wide field in order not to lack in suggestive- 

 ness along the various lines of interest of the Museum's visitors; thus of necessity 

 it touches many matters briefly. Again forestry is so rapid-growing a subject to-day 

 that even a few months are likely to put out of date these briefly stated facts along 

 certain pracl ical lines. The latest informal ion of markets and met hods as well as of 

 legislation on conservation at home and trade relations with foreign countries must 

 always be sought in later publications, such as Government bulletins and the 

 monthly periodical of the American Forestry Association. 



The chapter intended to help in the identification of trees in their winter condi- 

 tion, although covering trees represented by an armful of twigs which one might 

 gather in the Eastern United States, is so incomplete that it has been given a sub- 

 ordinate place as an appendix. The line cuts for t his chapter were made from freshly 

 gathered material, under the supervision of the author, by Miss Alma Field of the 



Rhode Island School of Design, Providence.
