UNDER SEA WITH HELMET AND CAMERA 



on the surface of the water inside the bucket. While I held the bucket 

 alongside my head, my companions on the platform in the tree lowered it 

 slowly and I went with it until my feet rested on the bottom. Air from 

 the bucket was drawn into the lungs and passed back into the bucket. This 

 air was at the same pressure as the water and there was no difficulty in 

 breathing, except that the air became foul after a very few breaths. Our 

 next improvement was to use two buckets, shift the tube from one to the 

 other, send a signal for the used bucket to be hoisted up, filled with fresh 

 air, and sent down again. This was rather complicated, the water was sel- 

 dom clear enough to see through at all, it was not as much fun as we had 

 anticipated; consequently, the diversion came to an end. Had we lived 

 where there was clear, still, salt water we surely would have evolved a real 

 diving apparatus.
