The color of the flesh varies a great deal more than that of other species, and has been the cause of their receiving two additional names: "Sea-trout" when of a reddish tint, or, as com- monly understood, '* salmon colored ; and " bull-trout " when the flesh is white or colorless. This difference in color is due to a different diet, the latter being not near as palatable as the tinted fish. teemed the most valuable of all their lake fish. The young are hardy, and very readily withstand the vicissitudes of transportation ; with equal facility, adapting themselves to the changed circumstances of pond culture. The adult weighs somewhere from 30 to 40 pounds, the flesh is white, and in flavor fullv on a par with the brook-trout. THE BROOK-TROUT. Sahno fontinalis. Die Bach-Forelle. La truite.
