The Navy is a great training school for the vouth of the Nation, wherein useful trades and occupations are taught in connection with the exclusively Naval and Military instructions given.

The present War gives Americans an insight into the need of keeping the Naval Service fully manned, and it is hoped that the publication of this volume may, in some small way, bring home to Americans the imperative necessity that confronts us of keeping our Navy and Marine Corps recruited to its full and authorized strength.

No man is too good to serve his country by enlistment in the Navv or Marine Corps.
