A model of 1/145 of the original ring-net was made according to TAUTI'S principle of model-net construction, and pursing was made in still water in different lapses of time which are suitably given by the same principle.
The form of net, photographed from a side at 4 successive periods in the whole course of pursing, are reproduced in sketches in Fig. 2. Each column was obtained in each pursing, slow or quick. The tension, which is known to act on the pursing line of the original net is of reasonable magnitude as compared with the breaking strength of it.
