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.

LITERATURE-(Continued)

Power (September)-New York

OF THE MORE IMPORTANT ARTICLES, "Gas Producers for Power," by Julius I. Wile, is perhaps the most interesting, especially to one engaged in the generation of power. In this article the chemical end receives due attention. The article describes both the suction and the pressure types and is well illustrated.

"Valves and Valve Gears," by Robert G. Griswold, explains in simple style and excellent diagrams, the action of the plain slide valve.

"Splicing Leather Belts," by W. E. Dixon, M. E., is another valuable contribution on this topic. The methods of using the scraper, opener, and splicing board, are well illustrated.

Among other articles may be mentioned:

The Power House of the Interborough Rapid Transit Company.

Curves of Performance, by W. H. Booth. Expansion Joints for Smoke Flues, by C. E. Flanigan.

Lubricating Oils, by W. M. Davis. European Practice in the Use of Superheated Steam, by Franz Koester.

"I have learned more from SYSTEM in five months than in ten years of hard study and knocks in business. It is worth ten times the charges for it. F. A. PHILBRICK, Baraboo, Wisconsin.
