Photographing the Sea
Photographs two miles down in the ocean have been taken with a massive automatic deep-sea camera and lighting arrangement, invented by Professor li Newton Harvey, of Princeton University, U.S.A. The submarine device has two windows of extra strong glass to resist tho tw'o-ton per square inch pressure en countered at that depth. The camera looks through one window and a beam of light is projected through the other. A timer operates the electric lamp and camera at predetermined intervals, and a motor winds the film.
