Sometimes in a letter, sometimes by wire, often accompanied by a request for special delivery service. Many times a passage is added: =“I am ordered up for examination and need the book right away.”= The point we make is this. The mere possession of a copy of Reserve Officers’ Examiner will not prepare you for examination for promotion or keep you in touch with the subjects it covers. You must know its contents. These may not be absorbed by the average man by a casual glance through the book. Its contents must be studied the same as you study anything else you want to learn. You should not put off getting your copy of Reserve Officers’ Examiner until the last minute—when you are face to face with your examination. Get your copy now. Devote a little time to the study of its contents. Then when the opportunity comes for promotion—as it surely will—you will be prepared for it. _Price, $2.00_ * * * * * * * * * * Steele’s _Prepared originally for students of the Army Service Schools in conjunction with their course in military history._ _Much has been written on the individual campaigns and battles that make up our military history, but this is the only single work that contains a comprehensive narrative of the whole down to and including the Spanish-American War._ _The present edition is a reprint from new type and plates of the work which originally appeared in 1909, and which has been unobtainable except in second-hand book shops for many years._ =Two handsome volumes in box= =Price, $10.00 per set= _A postcard will secure a copy for you_ * * * * * * * * * * EMPLOYMENT OF MACHINE GUNS _By Major_ WALTER C.
