Spying a radiovisiphone, Roger was hurrying toward it to make his report while Bevans explained things to the watchman, when the figure of a man in military uniform suddenly appeared in the disc. He read from a sheet of paper held in his hand: M. O. 318,246 Three flying globes sighted by U. S. S. P’s 347, 1098 and 221. 347 destroyed by strange green ray from one of the globes. 1098 and 221 shelling them without apparent effect when their radios were silenced. All combat planes in Zone 36 are ordered to report, fully manned, to division headquarters, and stand by for orders. General J. Q. Marshall. “Oh, boy! There’ll be some scrap, now!” said Roger, “but I’m afraid our planes won’t stand much chance against those green rays. I’d like to be in on it, though.” “I, too, sir,” said Bevans. Roger rapidly whirled the dials of the radiovisiphone, presently obtaining direct communication with President Whitmore, to whom he made his report. He was ordered back to Chicago at once, a plane being requisitioned from the flying field for the purpose. As he and Bevans were about to take off they noticed six combat planes, manned and waiting orders. These rose only a few seconds after they did. The air was now much warmer, the snow having been replaced by a faint drizzle of rain. This, too, subsided before they had flown half way to their destination, but a heavy fog, following the swift melting of the snow, made the visibility exceedingly low. Despite this handicap, however, the skillful Bevans landed his plane neatly on the roof of the Dustin Building, turning it over to another of Ted’s pilots to be returned immediately to the flying field. The cold weather had passed as quickly as it had come, and this fact added to the evidence that it had been directly produced by the giant green ray from the moon. Back in his office, Roger quickly communicated with his wife by wrist radiophone—then waded into the mass of work which had accumulated during his absence. According to the shop reports the great interplanetary vehicle would soon be ready for launching. But fully as important as this, he found that ten thousand pistol degravitors and a thousand large degravitors for use on combat planes were completed and ready to be loaded with the special anode-cathode ray batteries in process in another division. Turning to the report of the superintendent of the battery division, he found that a hundred of the large and five hundred of the small batteries were ready for use. Going to the safe, he took out the directions for assembling and firing which Ted had left, and after giving them a careful reading, ordered ten of the large and a hundred of the small weapons and an equal number of suitable anode-cathode batteries sent up to his office.
