OES anything in the plans and specifications for a home interest a client—especially 
a woman—more than the bathroom and its equipment. 
It is the comjort-center of the household; and so long as houses are built to live 
in, the far-sighted architect will take no chances there. 
He knows that if it is not satisfactory the house will be viewed through dark 
glasses and mountains made of mole-hills. 
The safe way is to specify bathroom, kitchen and laundry plumbing equipment 
that is manufactured throughout by one house, bearing the reputation that can be 
gained only one way. 
That’s ‘“‘WOLFF’S” line.

Tue AUTOMOBILE Hanp Boox. By L. El- 
liot Brookes. Chicago: Frederick J. 
Drake & Co. 12mo.; 701 pp.; illus- 
trated. Price, $2. 
With its alphabetical arrangement of 
topics and its inclusive scope, this hand 
book is a veritable encyclopedia for the 
automobile owner or operator. Its leather 
covers of red and gold seem to embrace 
every principle and part of the automobile. 
Those who have it in one of the earlier 
editions will be surprised at the amount of 
new matter that has been added. It em- 
bodies all the more recent improvements, 
and everything connected with automobile 
construction and operation is explained and 
illustrated. While the gasoline motor re- 
ceives, as is its due, the lion’s share of the 
space, yet steam and electric propulsion 
have by no means been neglected. Trans- 
mission, wheel construction, and repair 
work are each taken up in turn, and plates 
and sketches are used whenever they are 
necessary to a clear understanding of the 
principles under discussion. A chassis plan 
on a large scale is the subject of one insert, 
with its thousand-odd parts all numbered 
and named. With all this abundance of 
information and suggestion, the volume 
lives up to its name and just comfortably 
fits into the hand. 
Dyke’s AUTOMOBILE ENCYCLOPEDIA. By 
A. lL. Dyke, E-E. St. Louis: (eevee 
Dyke, 1911. 8vo.; 407 pp. Priceysas 
There are so many treatises of this nature, 
each one claiming some advantage over 
the others in arrangement or manner of 
expression, that it is becoming increasingly 
difficult to fairly appraise their qualities or 
to justly commend one above the rest. 
Here we have twenty-nine lessons, posi- 
tively packed with diagrams and illustra- 
tions. We are told how to choose, drive 
and maintain a car. Every point of con- 
struction and operation that it is necessary 
or advisable for owner or chauffeur to 
know is here given in the simplest language. 
One lesson is devoted to the rules of the 
road, the State laws, etc. These latter give 
the registration fee, the allowed speed and 
the required lamps. Another lesson covers 
the aeroplane and aerial engines. A chap- 
ter is given over to a discussion on build- 
ing a home workshop, a garage, and the 
overhauling of old cars. The final section 
is a dictionary of motor words and terms. 
We must accord a word of praise to the 
way in which the illustrations have been 
shorn of all intricacy, showing only just 
what. is necessary to the understanding of 
the question in hand. As a reference book, 
this should prove an acquisition to the 
motorist’s library. 
ELectric Pocket Book AND Diary. Lon- 
don: Technical Publishing Company, 
limited, 1911. 567 pp.; illustrated. Price, 
cloth, 50 cents net; leather, 75 cents net. 
This stocky little annual has been brought 
down to date, and new matter has been in- 
troduced on the various rotary-converter 
equalizer systems; on balancers and boost- 
ers; on metallic filament lamps, and on the 
Edison storage cell. Altogether a large 
fund of information is compressed between 
its covers, and a feature of its make-up is 
the section of blank pages at the back, 
ruled as a daily record.
