Tux primary title of this book, au and monosyllabic as it 
is, is comprehensive, and covers a very large field of research, with 
numerous ramifications. The subject, indeed, is so vast, that but 
little beyond Ea ad dhs to it have ever been attempted by a 
single writer. Forestry may be said to be the beginning of the 
of view. Mr. Boulger had a difficult task before him to do justice 
to such a nee in gre form of a handy manual. That he was 
fully alive to a will be gathered from the conclusion of his very 
Siodunt preface :—‘* How incomplete my work is may be gauged by 
the statement that, while there are undoubtedly several thousand 
woods used in various parts of the world, only about 750 are here

have necessitated a volume fully twice as large.” In the first 
chapter, on ‘‘ The Origin, Structure, and Development of Wood, 
and its Use to the Tree,” egeres Boulger travels, necessarily, over 
much of the ground gone over by previous writers, a list of the 
works referred to in the compilation ¢ of the book being given at the
