This noble and gigantic species, which equals, or even 

 exceeds, in size, the true Salmon [Salmo Salar), and is by far the 

 lai'gest of all the lacustrine or non-migratory Sa/monida, is 

 found in all the great lakes to the northward and westward of 

 Lake Erie, to the fur countries and the arctic region. It is 

 not found in any tidal rivers, and never visits the sea. The falls 

 of Niagara present an insuperable obstacle to its descent into 

 Lake Ontario ; but whether it exists in any of the smaller lakes 

 of New York, or the eastern waters of New England, does not 

 as yet appear to be fully ascertained. It has been taken by the 

 companions of Dr. Richardson and Sir John Franklin, in Winter 

 Lake, lat. 64^° N. ; but I cannot learn that it has been discovered 

 in any of the waters which discharge themselves southward by 

 the Mississippi or the Missouri. I doubt not at all that it 

 exists in the waters of the Great Basin and the Columbia, and 

 that it is one of the fish mentioned by Colonel Fremont, as taken
