e the torpedo from the submarine. English hospital
ships were attacked, and men unable to protect themselves were subjected
to danger because the Germans feared that something might be carried on
the boat which would prove valuable to the Allied forces in making war.

Dozens--even hundreds of vessels of all sorts--were sunk from week to
week. Food and supplies for the Allied forces were destroyed, until both
England and France were threatened with starvation.

All this was the work of the submarine.

One smiled twenty-five years ago when he read that highly imaginative
story of Jules Verne, "Twenty Thousand Leagues Under the Sea," and
wondered if it would ever be possible for man to create such a marvelous
underseas craft as that which the famous French writer described. Today
the imaginative detail of the submarine which the novelist described has
been crystallized, and the world has learned that dreams sometimes come
true.

Marvelous things have been developed by the war which is involving the
peace and security of the world, but no single device has had such an
effect upon the warfare and upon the methods of waging it as the
diabolical submarine, which, like an assassin in the night, sneaks upon
the great ships along the water highways of the world and sends them
with their human freight to the bottom of the ocean.

TORPEDO'S DEADLY WORK.

A giant cigar-shaped missile, whose nose is pointed with guncotton and
filled with high explosives--and which the world knows as the
torpedo--launches forth from the submarine, and speeding under the drive
of a propeller at the stern steers its way into the side of the
battleship or great steamship. The torpedo plunges into the bowels of
the vessel. There is a tremendous explosion, and the water-tight
compartments of the vessel are torn open; the boat fills, and the pride
of the seas is no more.

Had the vessel's master and her crew any warning? No; unless the
vigilant officer on the bridge should note a thin pole with a hooked end
projecting above the surface of the ocean some miles away, and turning
his glasses upon it discover that it is the "eye" of a submarine--the
periscope--which is protruding above the surface. Then he may turn his
larger vessel and ram the submarine, or change the course of his craft
so that the torpedo launched by the submarine will miss its mark, or
perhaps expert gunners may turn the muzzles of their rapid-fire guns
upon the underseas craft an
