NAVAL officers havefrequently had the
opportunity to observe that swarms
of sea-gulls follow in the wake of sub-
marines. The birds are, attracted by the
unusual spectacle of a whalelike monster
moving through the water, and are eager
to pick up garbage.
This observation which, in a few in-
stances during the present war, is said to
have led to the timely discovery of the
dreaded proximity of a U-boat, suggested
to Dr. A. D. Pentz, Jr., of New Brighton,
N. Y,, the plan of training the gulls to
follow in flocks in the wake of subma-
rines. He suggests the use of a hopper,
fifty-four inches long, made of sheet steel.
It is securely bolted to the top of a
submarine and filled with chopped
fish. This bait is released from time -
to time by the turning of a crank
operated from the inside of the sub- bY 4
marine used for training the gulls. | ©
The bait, which would naturally - :
rise to the surface of the water,
would attract the gulls and cause
them to follow the submarine.
