Add to ORKGstopper nthere is another method of catching the seal by what is called the stopper-net. Under this process one net is permanently fixed across a small channel - say between two islands - and another, called the entrance-stopper, is placed about one hundred yards to the north, one end being fastened to THE opposite island and the other end attached to a long piece of rope in such a way as to allow the net to sink entirely out of sight.PRINTED ITEM DNE-citHe draws on [inc].Used IUsed Sup3Used I[see 'seal nets' etc] STOP n: STOP NET, SEAL NET, stopper net, ~ net
