When a purse seine is laied out in the waters where there exists a strong under-water current, it happens not seldom to occur that the net is entangled by the current and a part of the bottom margin of the net is pulled into a purse ring with the purse line. For the purpose of getting out of this trouble, a series of model experiments based on TAUTI'S principle was made. The shape of the whole net and that of the purse line were photographed at various stages of pursing for various directions of current, when the cork line was held in a fixed circle. The results are summarized in Fig. 4 and 5, from which it is supposed that the entangling of the net may occure at a deeper part of the purse line at a comparatively eary stage of the pursing.
