TROUT BREEDING. 81

 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-

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

 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-

 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
