natural food) in sufficient quantities and at little expense, 

 this would be the best of all. A change of food would 

 also do them good, but we find that they will not readily 

 change their food. 



As to the quantity of food necessary for a given number 

 of trout. This is difficult to give exactly as it will vary 

 with the size of the fish and the season of the year, more 

 being required in moderate weather than when it is very 

 hot or very cold. For one thousand three year olds, about 

 five pounds of light or liver per day; for two year olds three 

 pounds ; but a very little trial will show just how much to 

 feed them. Feeding once each day will keep the trout, 

 over one year old in good condition. Feed slowly, and as 

 soon as thej' begin to refuse the food stop feeding them, 

 then you have the measure and feed a little less than this 

 quantity every day. We say a little less because we have 

 known cases in which owners of ponds being over anxious 

 to fatten their trout, have killed them by over-feeding. 

 Still this does not often happen, especially if they are fed 

 regularly. A trout after long abstinence will gorge him- 

 self to repletion ; but will not kill himself to-day if he is 

 reasonably sure of to-morrow's dinner. All animals ap- 

 pear to be wiser than men in this matter, and it is very 

 seldom that they will eat enough to do them injury no 

 matter how much may be given them. 



Salmon and salmon trout as we have heretofore re- 

 marked will, when they are young accept food that is 

 rather less finely prepared. Their food is of the same 

 general kind, but as they are larger fish they need more 

 of it. Salmon trout can be kept in confinement until 

 they weigh ten or more pounds, whereas the largest tame 

 trout we have had did not exceed four, but few reached 

 three, it being doubtful whether fish ever attain as full 

 development in the domesticated as in the wild state.
