THE DESIGN AND CONSTRUCTION OF OIL 
Encines. By A. H. Goldingham. 
New York: Spon & Chamberlain, 
1910. 16mo.; 260 pp. Price, $2.50. 
This work has been written with the in- 
tention of supplying practical information 
regarding the kerosene or oil engine, and 
in response to frequent requests received 
by the writer to recommend such a book. 
While many works have been published 
on the subject of gas engines, some of 
which refer to or describe the working of 
the oil engine, no other book, it is believed, 
is devoted entirely to the oil engine in de- 
tail. The work, it is hoped, will be found 
useful to the draftsman, the engine. at- 
tendant, as well as to those who own or 
are about to install oil engines. The classi- 
fication of vaporizers has. been adhered to 
as made some few years ago, and a repre- 
sentative engine with each type is described. 
ArTxKrnson’s SicN Partntinc Up to Now. 
By Frank H. Atkinson. Chicago: 
Frederick J. Drake & Co., 1910. Ob- 
long 4to.; 378 pp. Price $3. 
This is a very handsome book on sign 
painting and the design of show cards with 
valuable alphabets, which contain 96 de- 
signs of lay-outs and accompanying color 
notes. There are 75 alphabets embracing 
all standard styles, their modifications and 
alterations, together with comprehensive 
text covering all practical phases of the art. 
There are a number of illustrations in the 
first part of the book showing how the 
work is actually done. These are specially 
valuable and we have not the same in any 
other book. The work seems to be emi- 
nently practical and the technical matter re- 
flects the best usage in vogue at the present 
day. 
Tue MEDITERRANEAN CRUISE. Compiled 
by Bruce Millard. New York: G. P. 
Putnam’s Sons, 1910. 16mo.; 438 pp. 
Price, $2.25 net. 
The present volume is a standard up-to- 
date compendium for Mediterranean trav- 
elers and contains pertinent information as 
to all points usually visited in a winter's 
cruise in Europe, Asia, and Africa. In fact, 
with its use the student can successfully 
travel without other descriptive aid. It is 
particularly valuable, as Baedeker’s “Mit- 
telmeer” has not been translated into Eng- 
lish as yet. The. book, which is light in 
weight, is well printed in good-size type, 
thus doing away with the objection to most 
guide books. 
Wuat Pictures TO SEE IN EUROPE IN 
One SumMMeER. By Lorinda Munson 
Bryant. New York: John Lane Com- 
pany, 1910. 16mo.; 183 pp. Price, 
$1.50 net; postage, 15 cents additional. 
The average European traveler is over- 
whelmed by the enormous collections which 
are to be found in even the cities of second- 
ary importance. Thus, even in places like 
Nancy, Lyons, and Turin, we find impres- 
sive collections which require a long visit to 
thoroughly appreciate. The object of the 
present book is to eliminate the ninety-nine 
pictures and to concentrate the reader’s at- 
tention on the one remaining. The idea is 
an excellent one and has been well carried 
out. There is very little to be said in criti- 
cism of the text, but some of the illustra- 
tions are ridiculously and unnecessarily 
small, such as the “Moretto” in the Acad. 
emy at Venice, shown in Fig. 46.
