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 illustra
tions,—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. Special Offer and Terms in a Handsome Booklet
