WHAT THE FISH SEES 



What I have seen in the tank will have a most 

 profound effect on my methods of fishing in the 

 future, and I am sure I can now understand many 

 of the happenings along the stream far better. It 

 will be an added interest to study and try to under- 

 stand fly fishing in the light of optical laws which 

 govern what the fish sees.
