ing. It is supposed that a trout is very fond of grass- 

 hoppers, but the trout in one of our ponds which we have 

 fed for a long time with beef lights, will not look at grass- 

 hoppers, and will turn up their noses at the fattest and 

 juiciest worms, while the trout fresh caught out of the 

 stream, which we have put in a pond by themselves to 

 educate, will for weeks refuse the daintiest bits of lights 

 and liver. Hunger will after a time drive them to change 

 their food; but with the young ones we cannot wait for 

 this, as they will die off before they learn. As the fish 

 grow older and stronger more food must be given to them ; 

 when six months old, a bowl full of liver will answer for 

 t a thousand. While the fish are young, feed often; six 

 or eight times a day for the first two or three months ; 

 three times a day will do after three months until they 

 are a year old. 



Young salmon, young salmon trout, California moun- 

 tain trout, and above all young California salmon are 

 larger, have stronger appetite, and will accept coarser 

 food. For them, although at first the liver should be 

 made as fine as for trout when they are a few weeks old, 

 it will be hardly necessary to dilute it at all, and in the 

 course of a few months they will not only take th'e larger 

 pieces, often tearing them apart, but will scorn the finer 

 portion. At one time sour milk was almost exclusively 

 used for feeding young fish, but it has been given up. 

 Other foods have been tried, but with no better success. 

 The fish will not thrive on any of them as well as they 

 do on liver, and do not thrive on that as well as if it were 

 a natural food. 



As they grow older, other things may be substituted 

 or may be added to it as a change. They are fond of the 

 roe ot other fish, of the spawn of the horse-foot or king- 

 crab; of fish itself, and when they are large enough to
