170 REMARKS ON WORMS 



anglers can always bring home a weighty dish, if 

 not a basketful, after a day's sport. In the latter 

 end of June and in July the worm is most deadly 

 in sunshine; indeed, it is generally during that 

 period deadly only in sunshine ; and when the sun 

 glares all the water it is most deadly of all. The 

 reason of this, we are of opinion, is that trout can- 

 not see the angler so well when the sun shines on 

 the water as otherwise ; and when it causes the 

 streams and pools to glare or shine, the angler may 

 capture them even in shallow water at a few feet 

 from his rod-point, so difficult it would seem is it 

 for trout to see under such waters. When the 

 water is shining thus, the angler, if walking on the 

 river bed or on a level with it cannot see the river 

 bottom ; hence it may be assumed that trout may 

 have the same difficulty to contend with when try- 

 ing to observe objects on the land or in the upper 

 element. Through the medium of the water, re-

 sun's rays for the finny tribes ; but as trout have 

 no eyelids, we are of opinion that the rays that 

 reach them from strong sunlight, however much 

 modified by refraction, must to a considerable ex- 

 tent favour the angler's approach to their haunts. 

 We know, however, some good anglers who hold
