WHAT THE FISH SEES 



Flies in white water appear among the bubbles

 very visible from below the bubble area which is 

 generally not very deep. The brown hackle dry 

 fly (Figure 29) is not nearly so visible among the 

 bubbles.

 some cases the water was moving with wind, and 

 in others almost still. The fish sees anything from 

 Raphael's Cherub through Cubist art to Hinden- 

 burg, and all in rapid succession; no wonder he 

 cannot always recognize me. The light shirt 

 worn is almost blended with the sky in some of 

 the pictures. This indicates that light clothes

 reflected against the surface. The reflections of
