Mr. Moss states in the foreword that he has published his book because the American citizen were no longer a nation of shots, he cites the fact that of the 119,847 National Guardsmen on the rolls at the time of the Mexican Border incident 47% had never fired a rifle hence the reason for publishing. Originally published in 1917, when the author was stationed at Camp Gaillard in the Canal Zone. There is also an introduction by the then President of the National Rifle Association.
