12mo, cloth, illustrated and with colored jacket

The true story of the American Jackies of to-day--clean-cut, brave and always on the alert. The boys join the navy, do a lot of training, and are then assigned to regular service. They aid in sinking a number of submarines, help to capture a notorious German sea raider, and do their share during the taking over of the enemy's navy. A splendid picture of the American navy of to-day.
