intelligent growers. STEVENS has rendered a distinct service to phytopath- 
ology by summarizing in a compact, neatly bound volume such a vast body 
of knowledge in an increasingly important field of applied botany.—E. C. 
STAKMAN. 
A textbook of botany 
Under the title General Botany, DENSMORE? has added to the already 
numerous textbooks of elementary botany whose scope and content are suitable 
for use in the junior college or normal school. The headings of the first two 
and of the last chapter in the book, The relations of plants to the environment, 
The form and adjustments of the plant body to the environment, and Plant 
associations, show that ecology has been given due emphasis. The inter- 
ning chapters are devoted to plant anatomy, physiology, and morphology 
in a way that seems to fit the title of the book. There is even an attempt at 
the beginnings of classification, with the consideration of representative species 
and families from the spring flora. In a word, the material is sufficiently 
comprehensive that in the hands of a good ae it will furnish the basis of 
a good general introductory course in the subject. 
There is evidence in the volume that it comes as a result of a wide expe- 
rience in the laboratory and in the field. The illustrations are numerous, many 
are original, and several, such as those of diagrammatic life histories, are of 
more than usual merit. The addition of a glossary would have supplemented 
the usefulness of the volume.—GeEo. D. FULLER 
West African forests

The oil palm and palm kernel industry; The forest in relation to agriculture; 
and A bibliography of West African forests. Considerable space is also devoted 
to the native names for the various trees.
