20 FISHERMEN'S WEATHER 



very few, like the barbel, are apparently 

 only rarely caught during the winter 

 months, and roach appear to feed best in 

 frosty weather in some waters, while in 

 others, under the same conditions, they 

 seem to fast. 



Concealing Dr. B right's opinion that the ripple 

 on the water, which the majority of fly- 

 fishermen prefer even in rivers, and in lake- 

 fishing find indispensable, is of no service 

 in concealing the gut cast, has already been 

 referred to. It may be the correct one, 

 but it is fair to say that it is opposed 

 to the opinion current among fishermen. 

 The extent to which a strong or moderate 

 light, or a ruffling breeze on the surface, 

 may hide the fisherman's tackle cannot be 

 precisely determined, since such an esti- 

 mate would entail accurate knowledge of 

 how an object like an artificial fly appears 

 to the eye of the fish. Even the range 

 of vision in fishes is not known with any 

 certainty, though even so highly organised 

 a fish as a salmon is said to see an object 

 under water no more than six inches
