TROUT BREEDING. 81 



county), New York, a few years since, a farmer owning the 

 sources of a fine spring brook, made three dams on the 

 stream at small expense, and sold the property, which 

 cost him two or three thousand dollars, for ten thousand. 

 So wonderfully had the trout increased by natural propaga- 

 tion in a few years, that the place, otherwise of little value, 

 commanded this price for its fish. 



On Long Island, near the city of New York, a person 

 cultivates trout and allows anglers to fish his pond at a 

 price per day. His income from this source is about 

 twenty-five hundred dollars per annum, so I am informed. 

 The amount of his sales from young fish for stocking the 

 ponds of gentlemen, who keep these preserves for fly fish- 

 ing, I am not aware of. An advertisement in the New 

 York Tribune, reads: "10,000 Live Trout. Ponds on 

 Long Island, or near New York City, stocked with live 

 Brook Trout of one year's growth. Address Wm. Nichol 

 Islip, New York." I would say that trout of one year 

 generally command from ten to twelve dollars per hundred, 

 and are in demand amongst New Yorkers owning ponds on 

 Long Island. 



Mr. Ainsworth, in a letter to the Vermont Fish Commis- 

 sioners, gives an estimate of the profits which may be de- 

 rived from hatching and growing trout on a large scale. 

 As his figures have connection with the description of the 

 ponds, and both would occupy several pages, I must omit 

 them ; his showing is, that large profits will accrue from it. 



The following is an estimate of my own, based on my 

 experience in feeding curds. The number of trout is the
