One of the most fascinating phases of 
nature-study is that of photographing 
wild fishes. So many conditions enter 
into the making of a successful picture 
that a photograph of a wild fish, showing 
it in motion, with natural surroundings, 
calls for painstaking care and prepara- 
tion. 
The apparatus I have found to be 
necessary consists of a glass tank, 36 
inches long, 17 inches high and 7 inches 
wide, though I sometimes use a smaller 
one. I have notches, a little wider than 
2 (ANS Ol MAGS WS Wanel<, Eble MALO wove 
frame work at the ends, so that a piece 
of glass may be slipped into them, thus 
dividing the tank into halves or fourths, 
thereby bringing the fish close to that 
side of the tank which faces the camera.

with a speed up to a hundredth of a sec- 
ond, may be used, but I prefer a Graflex 
with a Zeiss-Tessar F 4.5 lens, and ex- 
pose from 1-100 up to 1-265 of a second, 
the light governing the speed used. While 
I have had very good results from this 
lens, I believe a Graflex equipped with a 
Convertible Protar VII would be even 
better. 
Other accessories should consist of a 
tripod, folding table on which to place 
the tank, a bucket or two, small net for 
removing fish from the tank, a rubber 
tube to siphon out the water, and a rub- 
ber window scraper with which to keey 
the glass sides and partition free frou 
bubbles and drops of water. 
Contrary to the rule of “first catch 
your rabbit,” it is necessary to procure 
material for the bottom of the tank and
