 ROMEYN BECK HOUGH, AUTHOR AND PUBLISHER 



HANDBOOK OPENED AT RED OAK. 



Observe that two pages facing each other are demoted to a species. In this way all of the trees 



are treated. 



SHIS work is ''photo-descriptive," in that the distinctive characteristics of the various 

 species are shown in carefully made photographic illustrations. So completely has 

 this plan been carried out. after a vast amount of experiment and field work, that 

 the book enables one who has never studied botany to easily identify the trees by com- 

 parison with its illustrations. It appeals alike to the amateur observer of trees, the lum- 

 bermen and the technical botanist. 



Its illustrations cover the field in the following five exclusive particulars : 



(1) Leaves and Fruits in fresh condition, against a background ruled into square 

 inches (a unique plan, original with the author) whereby natural sizes are at once ap- 

 parent, and so perfect are the pictures that even minute details, as nature of surface, etc.. 

 are distinctly shown. 



(2) Leafless Twigs, generallv a full season's growth, showing the characters by 

 which the trees may be identified in winter a revelation to those who have thought ft 

 possible to identify trees only in summer. 



(3) Typical Barks Of Trees as found in field and forest with natural environment, a 

 1-foot rule being affixed to indicate size. They show the characters by which the wood- 

 man knows the trees. 



(4) Wood Structures (transverse) of at least one species of each genus, magnified 

 fifteen diameters, to aid in the identifying of woods. This feature is of special value to 

 dealers and workers in woods. 



(5) Maps Indicating 1 Distributions of the various trees. 



The illustrations represent 690 negatives, all made on account of scientific value, and 

 the maps 191 line engravings. The text gives important information as to botanical char- 

 acters, habitats, uses, etc., and carefully prepared keys and a glossary. Royal octavo,
