FILMS BY WIRELESS.

WATCHING BATTLES PROM AN ARMCHAIR. WASHINGTON June 14t Mr. Francis Jenkins, a scientist, has successfully transmitted moving pictures by wireless. While the Secretary of the Navy (Mr. C. D. Wilbur) and other officials watched. Mr. Jenkins showed a picture of a revolving windmill which was sent from a station five miles distant. Within a year, Mr. Jenkins said, he hoped the apparatus would be perfect enough to send moving pictures to Australia. Mr. Wilbur said it was, possible, that officials, sitting in Washington, would be able to watch the progress of battles in the next war. The invention was tried successfully two years ago, when action; pictures were recorded in a room adjoining

that where the "radio eye," said to be the secret of the invention, was placed. The "eye," consisting of a polished mirror of gradual thickness, and a number of smaller mirrors in its revolution breaks up the image of t,he picture into thousands of flashes, reflecting them into a photo-electric cell. The flashes take a number of Btills of the moving object, and in producing them on the screen give continuity of action, similar to that of the cinema.

The leading banks are experimenting wit,h the "Telephotograph," for telegraphing cheques. As the time required for reproduc-

tion of the cheques perfectly is 90, minutes the system will not be of much use .in neighbouring cities, but it will be\ valuable between distant points. The first cheques were telegraphed from San Francisco, enabling completion within two hours of a transaction normally requiring ten days.
