150 SCIENCE OF FISHING. 



and that the motion is extended to the rod, line and fly. 

 It is not nervousness, but a practiced art. Fish the portions 

 nearest you first, gradually lengthening you cast and fishing 

 the waters farther away. It is neither necessary nor advisable 

 to fish long at any one place. 



When a trout takes the fly, strike quickly. Usually, only 

 a slight motion is needed, especially in stream fishing, but 

 on lakes where the fish are large, a good strike is required. 



Regarding the kind of fly to use, study the conditions 

 and try the flies that your judgment tells you are right; 

 if these fail, try others. Larger flies may be used in the 

 spring than in summer. It is best, if possible, to talk this 

 matter over with some person who has done considerable 

 fishing in the waters you intend to visit. On dark days, 

 and late in the evening, the brighter and lighter colors seem 

 to take best. 



In spring trout' may be found near the surface and on 

 the rapid streams. Later cm they retire to the deeper water. 

 In the Northern lakes they may be caught in about five or six 

 feet of water in spring and early summer. When the water 

 grows warm in summer, they can only be caught where 

 the streams empty into the lakes and where springs are 

 found along the shore. In summer they do their feeding 

 mostly in the evening, in the shallow water, and about the 

 mouths of streams. It is useless to fish in the northern 

 lakes in midday, in the middle of the summer, unless you 

 know the location of springs, and you can catch no trout 

 when thunderstorms are brewing. 



Much has been written regarding the sense of hearing 

 of fish, but the belief is quite common among those fisher- 

 men who have given the subject a little thought, that fish 

 do not hear. However, it is possible that they can hear a 

 shout, or loud talking, when they are in quiet water, and it is 

 advised that the angler make no more noise than necessary. 

 A heavy tread or a thump on the bank is readily felt by the
