Ltdy 910%. A2mon 38 pp nice mple 
This is a very valuable book for all who 
are interested in any way in shipping. It 
gives a list of companies with the names of 
the vessels under each; then comes a direc- 
tory of passenger steamers, giving the 
length, breadth, depth, horse-power, etc., 
of all vessels. The writer has found this 
book of great value in comparing tonnages 
and horse-power in disputed questions 
which have arisen. There are a number of 
excellent illustrations in the front of the 
book. The book is printed on light-weight 
paper, rendering it very convenient for ref- 
erence. It is attractively bound. 
THE Frow or Water. D. Van Nostrand 
Company, 1909. 8vo.; 228 pp. Price, 
$3 net. 
The present work is the outcome of a 
series of investigations begun several years 
ago with the object of finding a simple ex- 
pression for the phenomenon of flow in ir- 
rigation channels. The author hopes that 
his work will prove of interest and value 
to the student and useful to the practical 
engineer. He also hopes that it will stimu- 
late further research and thus tend to 
widen the field of hydraulic knowledge.

Low, Whitworth Scholar, M.I., Mech. 
E., Professor of Engineering, East 
London College, University of London.

Mr. Low has succeeded in crowding a 
great deal of matter between the covers of 
this text book for engineering students. It 
embraces strength and elasticity of ma- 
terials, the theory and design of structures, 
the theory of mechanics, and hydraulics. 
The matter is presented in a very clear and 
concise manner. The author believes thor- 
oughly in the importance of exercises to fix 
a subject upon the student’s mind. Accord- 
ingly a large part of the book is devoted to 
various exercises, there being 780 in all, 600 
of which are original. The remainder have 
been selected from various examination pa- 
pers. The book should occupy an important 
place in the student’s library.

Copper Industry of the World. By 
Horace J. Stevens. Houghton, Mich., 
1909. 8vo.; 1,628 pp. 
The book before us is most important 
from its vast array of facts as to the vari- 
ous copper properties of the world. The 
copper mines in various countries are dealt 
with, and there is an excellent glossary. 
There are also chapters on the uses of cop- 
per; substitutes for copper; brands and 
grades of copper; alloys of copper; electro- 
metallurgy of copper; pyro-metallurgy of 
copper ; hydro- metallurgy of copper ; milling 
and concentrating of copper; mining of 
copper; chemistry and mineralogy of cop- 
per; geology of copper, etc.

The kind reception given to the author’s 
little book entitled “Science Through 
Stories” emboldened the writer to choose

ple facts concerning the insect world, and 
she has selected one or more specimens of 
each of the seven great orders of the in- 
sect world according to the Linnean sys- 
tem of division.

BUNGALOWS 
A MOST artistic book of original concep- 
tions designed specially for the northern 
climates. It has 64 pages profusely illus- 
trated with color plates, half-tones, sketches 
and floor plans. 
The designer being a native of California has im- 
bibed the spirit of the true bungalow art, not only 
through association, but by experience in actual con- 
struction. This art has been applied in adapting the 
bungalow to the requirements of the sterner climates 
~ of the north. 
The book is bristling with interest and suggestions 
for the builder of either a suburban cottage or city 
residence. Price, Fifty Cents.
