destruction but instant surrender for the
submarine.
The reason why this does not work
on a large scale is because the Germans,
whatever else we may say of them, are
not lacking- in guile. The sight of two
or three "innocent" fishing smacks cruising
about—the net raisers—is enough to
make them very circumspect. Then, too,
when finally encircled, it is obvious that
the decoy vessel also is caught in the
same trap, and is for the moment, at the
mercy of the sea pirate. Many German
vessels thus caught have simply sent the
decoys to the bottom first, and then
taken their own medicine, which makes
the process of destruction of submarines
rather costly for the Allies.
Another idea, which has been featured
quite extensively in the United States,
but which contains little of practical
value, is typical of the wilder plans for
protecting the merchantmen themselves.
The inventor of this process proposes
that each ship carry an apparatus for
throwing steel discs—like phonograph
records—into the water beside the vessel,
at such an astounding rate that the
ship is enclosed completely by a thin wall
of steel through which a torpedo cannot
pass without exploding. This is, of
course, thoroughly Utopian, as no vessel
could afford the expense of using these
plates at all times, even were the apparatus
proved to be practical, and no
ordinary ship can tell with any accuracy
—unless protected by aeroplanes—when
an underwater attack by a German submarine
is about to start.
Literally thousands of such ideas have
been advanced in the past few months,
but it is probable that ninety-nine per
cent have not even been tried out,
although doubtless all have received
serious consideration. It is probable that
the U-boat problem will be solved
ultimately by the application of old principles,
and not by any astounding new
invention. The torpedo buoy is such an
application, and though it may not be the
best way, it has possibilities.
