THE STEW. 151 



poachers could not gain access to the shed 

 itself. Whenever the keeper is about to feed 

 the yearlings, he lowers the level of water in the 

 stew until all of them are in the tank under the 

 shed, and then distributes the food through one 

 of the trap-doors in the flooring. Sufficient 

 light comes in by the open door of the shed 

 and the window to admit of observation of the 

 fish while being fed. The only disadvantage 

 of this plan is that, when the stew is emptied 

 for the purpose of catching the yearlings, the 

 small quantity of water left in the tank has to 

 be bailed or pumped out. 



The level of the water in the stew is of 

 course dependent on the arrangement of the 

 various hatches. Thus, with the inlet hatch 

 fully open, and the screen at H down to the 

 bed of the stew, the flow of water is very rapid, 

 and the average depth of the stew is about 

 2oin. With a 1 2in. board below the screen at 

 H, the depth of water can be raised with safety 

 to about 2ft. 6in., but in such case the inlet 

 hatch is not so much raised, and the stream 

 through the stew is less rapid. 



All hatches, screens, &c, have, of course, Necessity for 

 adequate arrangements for raising and lowering, hatehes%c. 

 and, what is a matter of paramount importance 

 in such cases, staples, bars, and padlocks are 

 provided, so that the entrance to the shed, and
