The New Enemy of the Submarine.—A new enemy of the submarine has recently made its appearance—an enemy that will make it use a periscope of a new order.
This latest submarine destroyer is the airplane; and as the captain cannot now see directly overhead except when his boat is running light or awash, and the pilot of an airplane can see the submarine when it is submerged to a very considerable depth, it is easy for him to follow the undersea craft until she comes to the surface and then drop a bomb on her.
A story of a running fight between an airplane and a submarine would have put it in Col. Roosevelt’s Ananias Club a few years ago, but to-day it has all come to pass, and it looks now as if a good way to break the backbone of Germany’s ruthless warfare on the sea is to destroy the U-boats with a fleet of airplanes.
