AMERICAN SAIBLING 



choked with glacial ice, the quaternary trout, if of 

 marine ancestry, must have found their way into 

 this mysterious lake, following, like man and the 

 higher mammalia, but by watery channels, the 

 retreating ice-fields, and swarming into the basin 

 of Sunapee, excavated anew for their reception by 

 the erosive power of the glacier, and filled with its 

 melting snows. This quaternary charr or Alpine 

 trout — represented in the saibling of the moun- 

 tain lakes of Europe from Austria to Spitzbergen, 

 in the Dolly Varden {Malmd) on both sides of 

 Beering Sea, in the pygmy blue-back of Maine 

 (Oquassa), and in the large anadromous or sea-run 

 blue-back of Labrador — is believed to be the 

 ancestral type from which our common brook 

 trout is differentiated. It has simply found in 

 Lake Sunapee and Flood's Pond conditions for its 

 survival — in the purity of the water (Sunapee, 

 one and three-tenths grains of solid matter to the 

 gallon), in the depth of the water (both lakes over 

 one hundred feet), in the character of the bottom 

 (white sand and gravel), in the temperature of the 

 lower layers (Sunapee, 38° Fahr. to 52° Fahr., ac- 

 cording to depth and season), and in the abundance 

 of crustacean and fish food. 



The distinguishing features of the Sunapee 

 charr are : The presence of a broad row of teeth
