192 MARVELS OF FISH LIFE 



When it is desired to photograph a fish illuminated as 

 in nature, I shall fix a rough canvas tent in front of one 

 of the glass sides, which will take the place of the dark 

 chamber in the pond, and I shall bank up the other 

 glass side with rocks, reeds, or seaweed, and thus obtain 

 photographs of fish with the illumination entirely from 

 above, as in nature.
