SEA TROUT. 123 



breadth and thickness of the fish, and the comparative small- 

 ness of the head, which is produced by no alteration whatever 

 of that portion of the body, but by the increase and develop- 

 ment of the body itself, which, at this season and stage of 

 the animal, is equal, in its circumference, to one-half its 

 length. 



It is well known and undisputed in Long Island, that the 

 Pond-fish and Creek-fish, as they are termed, pass to and fro 

 between the fresh and the salt water ; and although the Creek- 

 fish are occasionally there called Sea Trout, it is by no means 

 as implying that they are of a difl'erent species, but merely 

 indicating the water in which they are taken. 



The fish to which I referred above in my introductory 

 remarks on the Salmonida, as being perhaps a distinct kind, 

 analogous to the Salmo Trutta of Linnseus, is by no means this 

 Trout, but a very difl'erent animal, found only in the eastern 

 and north-eastern rivers, which empty their waters into the 

 Bay of Fundy or the Gulf of St. Lawrence. This Trout is 

 found only in these rivers, and so far as I can learn, instead of 

 running up to the head waters of the streams in order to spawn, 

 comes up only to the foot of the first rapids with the flood, and 

 returns with the tide of ebb. Even about this Trout I have my 

 doubts, though before finishing this work, I hope to have more 

 definite information on the subject. 



With regard to the fish mentioned above, I have no doubts 

 whatever. It varies in nothing from the Common Trout 

 but in those particulars, which prove that it has run to the 

 salt water.
