Rural School Agriculture 
By Cuartes W. Davis. A book intended for the use of 
both teachers and pupils. Its aim is to enlist the interest of 
the boys oi the farm and awaken in their minds the fact that 
the problems of the farm are great enough to command all the 
brain power they can summon. The book is a manual of exer- 
cises covering many phases of agriculture, and it may be used 
with any text-book of agriculture, or without a text-book. The 
exercises will enable the student to think, and to work out the 
scientific principles underlying some of the most important 
agricultural operations. The author feels that in the teaching 
of agriculture in the rural schools, the laboratory phase is al- 
most entirely neglected. If an experiment helps the pupil to 
think, or makes his conceptions clearer, it fills a useful pur- 
pose, and eventually prepares for successful work upon the 
farm. The successful farmer of the future must be an experi- 
menter in a small way. Following many of the exercises are a 
number of questions which prepare the way for further re- 
search work. The material needed for performing the experi- 
ments is simple, and can be devised by the teacher and pupils, 
or brought from the homes. Illustrated. 300 pages. Cloth.

Agriculture Through the Laboratory and School 
Garden 
By C. R. Jacxsow and Mrs. L. S. DaucHerty. As its name 
implies, this book gives explicit directions for actual work in 
the laboratory and the school garden, through which agri- 
cultural principles may be taught. The author’s aim has been 
to present actual experimental work in every phase of the 
subject possible, and to state the directions for such work so 
that the student can perform it independently of the teacher, 
and to state them in such a way that the results will not be 
suggested by these directions. One must perform the experi- 
ment to ascertain the result. It embodies in the text a com- 
prehensive, practical, scientific, yet simple discussion of such 
facts as are necessary to the understanding of many of the 
agricultural principles involved in every-day life. The book, 
although primarily intended for use in schools, is equally 
valuable to any one desiring to obtain in an easy and pleasing 
manner a general knowledge of elementary agriculture. Fully 
illustrated. 5!4 x8 inches. 462 pages. Cloth. Net . $1.50 
Soil Physics Laboratory Guide 
By W. G. Stevenson and I. O. ScHaus. A carefully out- 
lined series of experiments in soil physics. A portion of the 
experiments outlined in this guide have been used quite gen- 
erally in recent years. The exercises (of which there are 40) 
are listed in a logical order with reference to their relation 
to each other and the skill required on the part of the studert.
