Trumbull White, Our War with Spain for Cuba's Freedom
“ It first must be understood that all modern guns on ships-of-war are breech-loading and rifled, and that the smooth bore exists only as a relic, or to be brought out in an emergency for coast defense, when modern guns are not available. From the thirteen-inch down to the four-inch, the guns are designated by their caliber, the diameter of their bore, and the shot they throw, while from that to the one-pounder they take their name from the weight of the shot. Everything below the one-pounder is in the machine-gun class. ”
