In the cover of fish baskets an opening is frequently made permitting the fish to be put in without lifting the cover. In traveling over rough places, or when the basket is full, some of the fish are likely to be shaken out, or may wiggle out of the basket. To guard against this, a leather flap can be provided covering the hole on the inside. At one end of the flap, four holes should be punched. It can then be placed in position and securely laced to the cover. The flap acts as a valve, allowing fish to be put into the basket, but preventing their escape.-Contributed by A. W.
