 filled with a plentiful supply of water from the stream. The 

 water is conducted from them into the yearling ponds 

 which are marked A by means of underground chan-

 making artificial redds off a stream, and illustrated in

Fig. 4 and Fig. 5. Note that the ponds A are at right

 ponds A receives an independent supply of waiter an import-

The water passes from the yearling ponds A through hori-

 The whole of the water supply to the fishery finds its way from
