GROWING THE LARGE TROUT. 229 



too, though some printed remarks on the subject have 

 made it appear complicated. 



The one correct thing to feed trout on * as a rule, is 

 the heart, liver, and lungs of animals killed for market. 

 These combine the three desired points of trout food. 

 They are cheap, accessible, and nutritious. 



They are cheap, averaging in the country about three 

 cents a pound. It is true that liver in thickly settled 

 places costs ten cents per pound, and if you should feed 

 the trout entirely on liver in those places it would be 

 very expensive feeding. But the lungs are quite as 

 good food for trout as liver, and better in some respects. 

 The lungs can be bought in any community for two 

 cents a pound. Sheep's and lambs' plucks can also be 

 bought for the same. As a general thing, in the more 

 thickly settled places the lungs and sheep's plucks are 

 cheaper than in the country, because of the greater 

 number of animals killed in such localities. While 

 food can be bought at these figures, trout can be profit- 

 ably raised at half the present market-prices. 



This kind of food is accessible. Wherever there is 

 a community of any size, cattle and sheep are killed 

 for its support, and wherever these are killed the 

 plucks may be procured. This class of food can al- 

 ways be obtained also at the great cattle markets, like 



* Since writing the above a new kind of food has been used 

 with great success at the Cold Spring Trout Ponds, viz., English 

 Dog Biscuit. It can be obtained of Mr. Francis O. de Luce, 18 

 South William Street, New York. It costs ten cents a pound, 

 and has many advantages over meat, particularly in being cleaner 

 and in not spoiling quickly, as meat does. I recommend its use 

 to all trout raisers.
