haustion of the famous "Black Earth Belt," and a financial policy based on hothouse-nourished industry and enforced exports.

The Russian problem is intimately bound up with the whole problem of mankind.

"A power which holds in its grasp one-sixth of the land on this globe of ours, is, in any event, no negligible quantity. For weal or woe, the cause of Russia is also our own cause. Her prosperity or degeneracy, the question whether her 130 millions will within the near future find or fail to find the form of government best adapted to their welfare and their development, concerns every one of us very closely." The volume is well worthy of study.

Modern Air-Brake Practice, Its Use and Abuse. By Frank H. Dukesmith, M. E. Pages 300. Cloth. Illustrated. Indexed. Published by Frederick J. Drake & Co., Chicago, Ill. Price, $1.50.

MOST BOOKS on the air-brake are in catechism form. This textbook is written in a general descriptive explanatory manner, the questions being grouped at the end of the sections. The author has divided the subject into three parts: First, the various parts of the air-brake, equipment, and functions; second, the various defects and their remedies; third, the handling of the brake, with tables and rules for computing brake power, leverage, etc. This book includes a short description of the "straight" air-brake as now used on electric railways, as well as the automatic air-brake on steam railroads. The volume has an excellent index, which enables one readily to find any subject desired.

NO TEXTBOOKS published in recent years have received higher commendation than "The Mother Tongue" series. Book II is a practical elementary treatise on English Composition. The manner in which the authors present the subject has many novel features, and cannot fail to hold the attention of the student. In New York State alone, over 400 schools are using this series. The three books are the com

This new edition of

Battles and Leaders of the Civil War

IS SOLD ON AN EASY PAYMENT PLAN

It has been prepared especially to meet the demand of an increasing population and a new generation. This work, in four volumes, 3098 pages, is the greatest exposition of the world's greatest war ever printed. It rivals the War Records themselves in completeness, authenticity and detail, and is vastly more interesting. Generals Grant, Sherman, Johnston, Beauregard, Col. Mosby, Capt. Ericsson, and hundreds of others, men from both sides, are its editors, making it accurate and impartial; its illustrations, over 1700,-maps, and diagrams give a panoramic view of this awful struggle; and its index, referring to every important person and event, with statistical tables of the opposing forces in every engagement, makes it a veritable

Cyclopedia of the Civil War.

What history is so complete? What history can be so complete ?

If you want a reliable source of information or a complete reference library, or love American history, you cannot afford to be without this work, especially at the reduced price and under the new plan of payment.

Napoleon Bonaparte:

A History. Complete in Four Volumes Editorially, mechanically, and artistically this work is a wonder. It is the only complete, impartial account of the great Emperor's life. All others have tended toward hero worship or erred to an equal extent on the other side. Professor Sloane was thoroughly equipped for this work through exhaustive study of all the Napoleonic literature obtainable and by extensive travel over the scenes of Napoleon's struggles, affluence, and subsequent downfall.

Eighty-seven artists have contributed to its pages, including the most famous military painters of France. About one-third of the three hundred pictures are reproduced in the original colors by a special process far superior to lithography. It is a veritable art gallery giving a pictorial history of the Napoleonic wars.

Boiler Construction. By Frank B. Kleinhans. Pages 421. Cloth. Illustrated. The Derry-Collard Company, New York, Publishers. Price, $3.00.

THE FIRST IMPRESSION one gets from this book is that it is devoted largely to the locomotive type; but the reason is readily understood when one considers that the operations on other boilers are much more simple, while the methods and maIchinery are the same.

A valuable feature is the clear explanation of the way things are done and the tools used in doing them. The illustrations are very clear and readily understood. The following are some of the processes that deserve mention here: Laying Out Gusset Sheet, Dome Base, Tube Sheets, Throat Sheets; Flanging; Punching; Planing; Bending; etc.

Boiler-Shop Machinery is illustrated by excellent half-tone engravings. Tables give valuable information regarding dies and punches, rate of driving rivets, etc.
