and then the two ends brought together and the net hauled in by the long ropes. 

 The position of the pocket is indicated by a large float, which enables the men to keep 

 it in the right position. 



In the streams which enter the lake two sorts of traps are used for catching fish. 

 The one called a " gawaby " is cone-shaped and made of the dried stalks of reeds 

 lashed together (fig. 19). It has two openings so arranged that when the fish pass 

 through the smaller one they are unable to find their way out again. At the other end 

 the reeds are fastened together by a cord, which can be easily undone and the catch 

 shaken out. A loose barrier is built across the stream so as to allow the water to pass 

 down, but to check the passage of the fish up-stream. The traps are placed in 

 openings in this barrier, and the fish coming up-stream to meet the fresh water force 

 their way through the openings into the traps (diagram 20).

The other trap is very ingenious, but one may spend hours watching it with very 

 small results. It is known as a "ganoon" (diagr. 21), or, more correctly, "anoon," 

 and is a net in the form of a pocket, about 2 metres in length and with a f -inch mesh. 

 Part of the mouth is fastened to a pole, the butt end of which rests on the bank. 

 The net can be raised or lowered into the water by means of a cord attached to the 



further end of the pole and kept in position by another cord. A cord of fine 

 twine runs across the mouth of the net, to which are attached other pieces about 

 6 inches apart, which, hanging down vertically, are attached to the submerged edge of 

 the mouth of the net ; this cord is held in the hand when the net is in the water. A 

 small dam is built out in the water, about 5 yards above the net, causing the stream,
