Fig. 6. An illustration of the need for camera shelters. The equipment was not seriously damaged. pictures taken on the Fastax camera at the higher frame rate showed a definite pulsation in the intensity of the illumination. If it were a matter of any importance this could perhaps be overcome by operating the commutator at a different speed, to change the overlap on the peaks of the light output curves from the flashbulbs. The only serious damage sustained by the equipment used inside the structures is shown in Fig. 6. It is pleasant to be able to say that the Fastax cameras gave trouble-free operation in spite of rough handling and frequent exposure to adverse conditions of excessive dust and moisture. Toward the end of the program, automatic cutoff switches were installed which at first functioned beautifully, but after six weeks one of them stuck shut. Since the camera was timed to catch the event on the last 25 ft of the 100-ft roll, most of the film on which the event was recorded was beaten to confetti during the lengthy over-run. R. M.
