These eight impressions could be made visible only by subjecting the "paper" to different colors, the color rays bringing out the different prints. The seven colors of the rainbow were used, while white light was employed to show reproduced photographs, etc., in their natural colors. With this method it was possible to "print" a "newspaper," fully ten times as large in volume as any newspaper of the 21st century, on a piece of film, the size of a postage-stamp.
Each paper published an edition every 30 minutes, and if one did not possess a projector, one could read the "paper" by inserting the News in a holder beneath a powerful lens which one carried in one's pocket, folded when not in use. To read the eight different pages, a revolving color screen was placed directly underneath the lens, to bring out the different colors necessary to read the "paper."
Ralph, 124C 41+, glancing over the head-lines of his News, saw that considerable space was given to his latest exploit, the paper showing actual photographs of the Swiss Alpine scene, which a correspondent had taken as the avalanche thundered down the mountain. The photographs had been sent by Teleradiograph immediately after the occurrence in Switzerland, and the News had printed them in all the natural colors twenty minutes after Ralph had turned off the ultra-power in New York.
These photographs seemed to be the only thing that interested Ralph, as they showed the house and the surrounding Alps. These, with the monstrous avalanche in progression photographed and reproduced in the natural colors, were very impressive.
Presently he revolved the color screen of his projector to green—the technical page of the News—to him the most interesting reading in the paper.
He soon had read all that interested him, and as there was still an hour before dinner time he began to "write" his lecture: "On the prolongation of animal life by π-Rays."
He attached a double leather head-band to his head. At each end of the band was attached a round metal disc that pressed closely on the temples. From each metal disc an insulated wire led to a small square box, the Menograph, or mind-writer.
He then pressed a button and a low humming was heard; simultaneously two small bulbs began to glow with a soft green fluorescent light. Grasping a button connected with a flexible cord to the Menograph, he leaned back in his chair.
After a few minutes' reflection he pressed the button, and at once a wave line, traced in ink, appeared on a narrow white fabric band, the latter resembling a telegraph recorder tape.
The band which moved rapidly, was unrolled from one reel and rolled up on another. Whenever the inventor wished to "write" down his thoughts, he would press the button, which started the mechanism as well as the recording tracer.
