I20 Forestry Quarterly 



The crown habit of a few species is illustrated by drawings or 

 photographic reproductions. The descriptions include many 

 personal notes on the silvicultural characteristics and associates 

 of the trees described, and occasional notes on the relative im- 

 portance for forest or park purposes. The structure and physical 

 characteristics of the wood of a number of species are briefly 

 described and a series of plates in color are intended to assist in 

 the identification of the species. It is impossible from these 

 plates, however, to get more than the vaguest notion of the 

 structure or physical properties of the wood. 



A number of new species are described. It appears to the 

 writer, however, that it would have been far better for these 

 descriptions to appear in a technical paper, rather than in a 

 general work of this character. 



A section of the volume is devoted to a number of general 

 rules necessary to observe in the growing of exotic species. 

 These are largely based upon biological principles and apply as 

 well to the growing of exotic species in this country as in Europe. 

 Special lists of trees are given suitable for different forestry pur- 

 poses, on various soils, in each climatic zone. These lists are 

 very complete and should be of interest to American foresters. 

 Special lists are also given for park and other decorative planting, 

 for the flowers, foliage, color effects, etc. General instructions 

 are given regarding the protection and training of exotic species. 

 A brief account is given of the propogation of plants for decorative 

 purposes by budding, grafting, cuttings, etc. 



The volume contains a large amount of exceedingly interest- 

 ing information regarding the more important trees of the 

 northern hemisphere and in many respects it is as useful to 

 Americans interested in trees for forestry and park purposes as 

 it is to Europeans. J. W. T.

When the second edition of this volume was published in 1896, 

 the author stated that alterations in the original plan were likely 

 to be introduced. Accordingly the third edition of Volumes I 

 and II have been re-arranged. The second half of Volume I, 

 ' ' The Foundations of Silviculture, ' ' has been transferred to 

 Volume II in the third edition which appeared in 1904 — and in
