Whistle Warns of Fish Catch
When the Fish Strikes the Bait the Water is Forced Up into the Whistle Suddenly, and the Escaping Air Warns the Fisherman
A toy railroad wheel, a piece of hollow cane, and pieces of wire are the materials necessary for making the whistle shown in the illustration, which warns a fisherman that a fish is attempting to make away with his bait. The wheel is fitted into the end of the cane and wedged into place to form a tight joint. The wires are formed into loops at the ends of the cane and fixed to it. The whistle is attached to the fishline, as shown, with the open end down and slightly below the surface of the water. The fishpole may be fixed so that the whistle will remain in this position while the fisherman is at ease in the shade near by. When the fish attempts to make away with the bait, as shown in the sketch, the water forces the air in the upper part of the cane out through the center hole of the wheel, and a whistling sound is the result.
