danger of having too much of. The present volume by the author of 
the Glad Book gives an account of how the happiness of one life ra- 
diated out to others and increased their joy and usefulness. 

Alma's Junior Year. By Louise M. Breitenback. Boston : The Page 

Company. Pp. 376. $1.50. 

This is the third volume in the Hadley Hall Series and shows Alma 
in a new capacity. She now has different problems to solve and new 
associates, but possesses the same charm and friendliness as when a year 
younger and a sophomore. 

Kssentials of Business Arithmetic. By George H. Van Tuyl. New 
York : American Book Company. Pp. 272. 70 cents. 

Trigonometry. By Frederick Anderegg and Edward Drake Roe, Jr. 

Boston : Ginn and Company. Pp. 108. 75 cents. 

In this revised edition some demonstrations, which experience has 
proved too technical for the average elementary student to understand 
easily, are simplified without loss of vigor or generality; many examples 
which illustrate the practical side of trigonometry are added; and model 
solutions for the various cases of the right and oblique plane triangle 
are given. The book represents an effort to give as much trigonometry 
as is needed in an elementary course, with possibly the addition of a few 
examples to arouse the interest and test the ability of the stronger stu- 
dents, and is intended for the use of seniors in high schools and fresh- 
men in colleges.

Diary and Time-Saver for 1914, published by Laird and Lee, of Chicago, 
is up to its usual standard of excellence and costs but 25 cents. 

American Ideals, Character and Life. By Hamilton Wright Mabie. 

New York: The Macmillan Company. Pp. 341. $1.50 net. 

The author of this book was our exchange lecturer to Japan and for 
the most part the addresses given were those delivered over there on the 
development of the American people. From its sane position it should 
do much in giving a more accurate view of the American spirit than that 
usually held. 

Syllabus of Plane Geometry. Arranged in Groups for Emphasis and 
Method. By Robert R. Gaff, B.M.C. Durfee High School, Fall River, 
Mass. Price 25 cents.
