258 Fortieth Annual Meeting 



sandy beach upon which was placed the pedestal mounted 

 on trucks. This plan admitted of turning the aquarium at 

 will so that it could be brought into nice adjustment from 

 time to time as the changes in the light required. A large 

 hood, eight feet on all dimensions, was then made of light 

 poles and covered with tar paper which was nailed on and 

 held firmly in place by an old fish net. A generous supply 

 of fish was caught, the tank was filled with water, the 

 camera was set up and tested, and everything was perfectly 

 satisfactory. My assistant and I were busily engaged at a 

 little distance attaching the sea moss to the large white sheet 

 that was to be used as a background, and after the tank had 

 stood full of water for a half hour at least, one of the plates 

 of glass suddenly and without warning broke, deluging the 

 dark hood, camera, and the seashore generally, and throwing 

 the jagged fragments of glass for fifteen feet or more in all 

 directions. Since accidents must happen, we were humbly 

 thankful that we were at a safe distance when this one 

 occurred. 



Having mastered the principles, but being without a 

 motion-picture camera, and satisfied that such a picture could 

 be made, I joined forces at this juncture with my friend, 

 Mr. R. K. Bonine, who had an excellent motion-picture 

 equipment, and whose skill in its use is well known. I had a 

 new tank constructed like the old one, except instead of 

 %-inch glass, inch plate glass was used for the sides, and 

 incidentally I may say that six men were required to lift the 

 finished aquarium into its place. 



Judged by the results, I feel safe in saying that our 

 equipment worked perfectly and the films and pictures are 

 sufficient reward for the time, trouble, and expense involved 

 in securing them. Naturally many interesting facts too 

 numerous to detail here connected with the manipulation of 

 the equipment were found during the course of our experi- 

 ments. Worthy of special mention, however, was the fact 

 that by reversing the usual procedure of photographing 

 away from the source of light, excellent results were
