 AND EXTENT OF THEIR SENSE OF SIGHT, HEAR- 

 ING, TASTE, SMELL, AND TOUCH 



There are two genera of the salmonoids, popu- 

 larly called brook trouts, that are more highly or- 

 ganized than the salmon-trouts ; they are known 

 as charrs. They live and thrive in wild waters of 

 a temperature not more than sixty-five degrees, 

 and, in whatever stream they may be, they con- 

 stantly seek the higher reaches to spawn. If the 

 mouth of their home waters is not distant from, 

 and is in junction with, a salt estuary with no 

 physical impediment, so soon as the ice forms in 

 the stream the brook trout goes down into deeper 

 water, and subsequently migrates and adapts 

 itself to living in the water of the sea. Below 

 the southern line of tlij state of New York there 

 appears to be, however, a barrier of warmer water 

 into which the brook trout does not enter, in
