GEORGE BANCROFT, TO WHOM THE NAVY IS INDEBTED F O K THE UNITED STATES XAVAL ACADEMY, THIS WORK EESPECTFULLT DEDICATED. ; rilEFACE. This work, originally designed merely as a text-book for the Naval Academy, has been allowed to depart from the essential character of such a work, in the hope that it might prove more ac- ceptable to the Navy generally. The compiler of this volume, when ordered to take charge of the instruction in Naval Gunnery at the Naval Academy, could find no single work that would cover the ground necessary for an ele- mentary course in this branch. Many good works were at hand, but each bore on some speciality of the author, which it seemed to have been his object to set forth ; no one volume was sufficiently comprehensive to supply the want ; it became necessary to compile from each such parts as, when united, might embrace the whole subject. This volume is the result of the author's effijrts to achieve this object. In submitting his work to the Navy, the author desires to be understood as simply making an eflTort to circulate information which many officers, owing to constant service afloat, may not have been able to collect. This information he has endeavored to throw together in a readable and familiar form, and has avoided as much as j)ossible all scientific demonstrations, making the work elemen- tary in its charactei". He is well aware that, had this duty devolved on many of his brother officers, it would have been better executed but, trusting to the generous character of the profession, he believes that his V, ork will be generously dealt with. : : 8 PREFACE.
