body. It is a "gregarious and deep-swimming fish, shy of 

 taking the bait and feeding largely at night-time. It appears 

 to require very pure and mostly deep water for its residence." 

 It is less tenacious of life than the trout. It reaches a weight of 

 from one to five pounds, probably rarely exceeding the latter 

 in size. The various charr described from Siberia are far too 

 little known to be enumerated here. 



Of the American charr the one most resembling the European 

 species is the Rangeley Lake trout (Salvelinus oquassa). The 

 exquisite little fish is known in the United States only from 

 the Rangeley chain of lakes in western Maine. This is very 

 close to the Greenland charr, Salvelinus stagnalis, a beautiful 

 species of the far north. The Rangeley trout is much slenderer 

 than the common brook-trout, with much smaller head and 

 smaller mouth. In life it is dark blue above, and the deep-red 

 spots are confined to the sides of the body. The species rarely 

 exceeds the length of a foot in the Rangeley Lakes, but in some 

 other waters it reaches a much larger size. So far as is known 

 it keeps itself in the depths of the lake until its spawning season 

 approaches, in October, when it ascends the stream to spawn. 



Still other species of this type are the Sunapee trout, 

 Salvelinus aureolus, a beautiful charr almost identical with the

European species, found in numerous ponds and lakes of eastern 

 New Hampshire and neighboring parts of Maine. Mr. Garman 

 regards this trout as the offspring of an importation of the ombre 

 chevalier and not as a native species, and in this view he may 

 be correct. Salvelinus alipes of the far north may be the same 

 species. Another remarkable form is the Lac de Marbre trout 

 of Canada, Salvelinus marstoni of Garman.
