The contents of this book, which originally appeared in a serial form in the Outing Magazine of Boston, represent the details of the expedition led by General Crook to the Sierra Madre, Mexico, in 1883; but, as the present military operations are conducted by the same commander, against the same enemy, and upon the same field of action, a perusal of these pages will, it is confidently believed, place before the reader a better knowledge of the general situation than any article which is likely soon to appear.”
