NAVAL officers have frequently had the opportunity to observe that swarms of sea-gulls follow in the wake of submarines. The birds are, attracted by the unusual spectacle of a whale like monster moving through the water, and are eager to pick up garbage.
This observation which, in a few instances 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 submarines. 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 submarine 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.
