THE EASTERN BROOK TROUT. 
THE BROOK TROUTS OR CHARS. 
Here comes another trout that I must tickle, and tickle daintily. I’ve lost my end else.

/^\UR Brook Trouts belong to the division of the Salmon family known to 
the English as “ Chars,” a group confined, for the most part to fresh¬ 
water lakes and streams, and distinguished from the true Salmons by a 
peculiar arrangement of teeth on the vomer, and also by their very small 
scales, and usually by numerous crimson or orange-colored spots, which 
are especially conspicuous in the breeding season. The Chars of Europe 
are, as a rule, lake fishes like the Saibling. On the other hand, the Chars 
of North America are usually found in streams and rivers. 
There is probably no group of fishes in which individual specimens 
and communities inhabiting certain areas of water show more tendency 
to variations in color and form than they do in the salmon family. Dr. 
Gunther has very justly remarked : “We know of no other group of fishes 
which offers so many difficulties to the ichthyologist with regard to the 
distinction of the species as well as to certain points in their life-history. 
Although this may be partly due to the unusual attention which has been 
given to their study, it has revealed rather a greater amount of unexplained 
fact than a satisfactory solution of the questions raised. The almost in¬ 
finite variations of these fishes are dependent upon the age, sex, and 
sexual development, food, and the properties of the water.”
