Nos. 293 & 294. Prawn Pots. 
These are used in Lake Biwa in the province of Omi. They 
are made of bamboo splints. At the entrance is a funnel-shaped 
piece with its smaller end projecting into the interior, so that any 
shrimp that has once entered it can not again get out. When 
being used, dozens of these traps are tied to a long rope, and crushed 
shell-fish (Corbicula or Paludina) are put within each; then the 
whole is sunk to the bottom. 
They are taken out from time to
