456 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 
The book is divided into four parts, which deal respectively with 
the plant, the soil, field crops,. and field management. The information 
is concise, is conveyed in non-technical language, and is intended to 
supplement but not to supplant practical instruction in the field. 
While intended for students in the United States, the book contains 
much of interest to the farmer in this country. The crops and some 
of the methods of cultivation in the United States naturally differ 
from those in this country, but the principles underlying crop- 
production are of course the same, and the necessity for running a 
farm on business-like lines, on which the authors insist, is evident 
wherever agriculture is practised. 
The illustrations are numerous, and the pithy legends attached 
to them in most instances impart a lesson more forcibly than the 
text. 
The appendix gives a list of the numerous agricultural colleges 
and experimental stations that are scattered throughout the United 
States, together with useful tables and statistical information, and a 
glossary of terms used in agriculture. 
" A Glossary of Botanic Terms." By Dr. B. D. Jackson. Ed. 3. 
8vo. x + 428 pp. (Duckworth, London, 1916.) 7s. 6d. net. 
Every science, like every trade and profession, has a number of 
terms peculiar to itself, either in form or meaning. Botany is no 
exception ; indeed, some would be inclined to say that it is a science 
more overloaded with technical terms than any other, and it is certain 
that a good many are likely to be deterred from its close study by 
the difficulties of learning what is in many cases a new language. 
The present glossary contains about 10,000 references to what, for 
want of a better term, may be called main-terms, besides numbers 
of others derived from these. Many of these are not in common 
use, of course, but that makes it more desirable than it would other- 
wise be to have at hand such a book as this, to which one may turn 
in the confident expectation of finding even the most unusual terms 
and their meanings. Even so, not all the terms used in botanico- 
horticultural works are to be found (and of course the author does 
not claim to include them). The special use of " abaxial " in Hogg's 
" Fruit Manual," for instance, does not appear. On the contrary, some 
technical terms peculiar to horticulture are included, e.g. " forcing," 
" grafting," " budding," " inarching," and so on, but not " pruning," 
" ringing," and the like. 
Amateur, student, and expert alike will find this book of constant 
value for reference, for not even the last can hope to carry in his 
mind the precise meaning attached by different authors to the terms 
they employ, and every new phase of the subject brings into use a 
new crop of terms with which none but the specializing expert can 
hope to make himself familiar. The last new phase of botanical 
study — Ecology — has added an enormous number to the already-
