HoxME Nature-Study Course. 



The zi'ork of the pupils of the Home Nature-Study Course is to com- 

 plete these pictures of fishes given in outline by adding the colors and 

 markings according to your own observation. You may use ivater color, 

 pencil or ink. If you are not able to find all these fishes, you can at least 

 find tzvo or three of them, and a careful study of the ones you find zvill 

 be considered satisfactory. 



Black-nosed Dace. 



The black-nosed dace is found in shallow, swift water with a stony or 

 gravelly bottom. It feeds largely on aquatic insects and may be recog- 

 nized by a black lateral band which extends around the nose. In the 

 "spring the male has a salmon-colored band in place of the black one. 



Johnny Darter. 



In shallow, clear streams with a fairly swift current and a gravelly 

 bottom may be found the little Johnny darters. You will find them under 

 the stones or in the ripples darting from one stone to another. The 

 darters have no air bladder ; the food of the Johnny darters consist almost 

 entirely of insect larvse. The head is short ; with eyes nearly on the top ; 

 there are brown w-shaped marks on the sides.
