their diet. All required to prosecute the business is a compara- 

 tively small capital, and whoever is first in the field has the best 

 chance, for ere long this great wealth will be utilized by those 

 whose means will be ample enough to enable them to monopolize 

 the largest share. 



The species enumerated, and the brook trout, {S. stellatits), are 

 the only fishes frequenting the fresh waters of Alaska, that have 

 much interest for mankind in general. 



Passing now to the more immediate and better known regions 

 of the great Northwest, in which we include all that country which 

 lies beyond the Upper Mississippi River, and especially that be- 

 yond the eastern foot hills of the Rocky Mountains, we shall 

 attempt to particularize all the recognized varieties except the sea 

 salmon, which we prefer to class among the fishes of the Pacific 

 Coast, under which head they will be found. The following list is 

 given by D. S. Jordan and Herbert E. Copeland in their paper en- 

 titled " Check List of the Fishes of the Fresh Waters of North 

 America," (Bitlkfin of the Buffalo Academy of Natural Sciences, 

 p. 144, December, 1876.)

 Of these, the names marked with " d. s." in italics may be con- 

 sidered as doubtful species requiring revision. They may prove 

 only synonyms of at present well known species.
