What A Cannon Ball Can Do.

In dweiling upon the wonderful power of the guns of the Indiana, Albert Franklin Matthews, in an article ou "The Evolution of a Battleship" in The Century, gives illustrations from the recent Chilean civil war, showing the effeotiveness of the smaller sizes of breechloading rifle guns. A shotweighing 250 pounds from an 8 inch gan of Fort Valdivia in Valparaíso karbor struck the crutser Blanco Encalada above the armor belt, passed through the thin steel plate on theside, ■went through thecaptain'g cabin, too the piliow from under hi3head, dropped his head on the mattress with a thump but without injuring a hair, passeci through the open door into the messroom, where it struck the floor and then glanced to the ceiling Then it went througha wooden bulkhead an inch thick Into a room 25 by 4 2 f eet, where 49 men were !eeping in hammocks It killed six of them outright and wounded six others. three of whom died. after which it passed through a steel bulkhead 5 inches thick and ended ir= course by striking a battery outside, in which it made a deut nearly two inches deep It was filledwith sand. Had it reieased deadly gases no one knows what damage i 5 might have done. A 450 pound missile from a 10 inch gun in the same fort etruok the same essel on its 8 inch armor. It hit square on a bolt. The shell did not pierce the armor, but burst outside the vessel. It drove the bolt clear through, and in its flight the bolt struck an 8 inch gun, completely disabling it. Such is the power of the smaller sized guns.
