ay 8 The Trouts of America 



York waters in November, and have been found 

 to continue to do so until February, the ova 

 hatching out in about sixty-five days at an 

 average temperature of forty-five degrees. 



In Great Britain many experiments have been 

 made in crossing the brown trout with other 

 species, one of the most interesting being the 

 cross between fario with our native charr (fan- 

 tinalis). The progeny are marked like a zebra, 

 hence their name, " zebra trout," of which it is 

 said that at one time they lived in a stream at 

 Ringwood, New Jersey, on the estate of Hon. 

 Abram S. Hewitt, where they were the result of 

 a cross between our brook trout and the brown 

 trout as in England. These zebra trout are 

 barren and greatly subject to deformation ; they 

 rise viciously to the fly, leaping into the air for 

 it ; they also leap on a slack line when hooked, 

 the latter trait being one I have never seen 

 shown by our much loved red-spotted charr. 

 Crossing the salmon-trouts with the charr-trouts 

 results in mule fish, not breeders; but the inter- 

 breeding of the charrs with other of the same 

 genus brings forth fertile progeny, and crossing 

 the salmon-trouts with salmon-trouts has a 

 similar result.
