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:

Jt 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. Pates 421. Cloth. Illustrated. The Derry-Collard Company, Hew 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 machinery 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 Rase, 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.

Telephone Principles and Practice. By George

Wilder, Ph. D., Assistant Professor of Electrical Engineering, Armour Instituteof Technology. Pages 445. Cantwell Publishing Company, Madison, Wis. Price, $2.00, postpaid.

This is a new book in the telephone field, and consequently has the prime advantage of being thoroughly up-to-date. The aim of the book is to treat fully the fundamental principles of telephony, and their applications to telephone apparatus as designed, manufactured, and operated to-day. This the author has succeeded in doing admirably, in a clear and concise manner.

The subject is treated in four sections. The first covers the principles of physics and electricity, which are necessary for the reader to grasp in order to be able to apply them to the construction and operation of the telephone circuits. The second section relates to the details of subscribers' instruments. The third section treats of party lines, and of the management of small exchanges belonging to the Generator Call or Local Battery type. The fourth section deals with the construction of small exchanges, party and toll lines, their electrical properties, and their protection against lightning.

The book is profusely illustrated, a particularly valuable feature being circuits of the various phones in actual use to-dav.
