accurately. They were, in their greatest dimension, perhaps twice the height of a man, and at close range their reddish color was more brilliant than I had imagined; in the thickest portion of the crescent, which seemed to be the nucleus, the radiance of the thing was almost blinding. It was obvious that they were not material bodies. There were no definite boundaries to their[409] bodies; they faded off into nothingness in a sort of fringe, almost like a dim halo. [409] An attention signal sounded sharply, and Kincaide groped his way swiftly to answer it. "It's Correy, sir," he said. "He reports his rays are utterly useless, and asks for further orders." "Tell him to cease action, and report here immediately." I turned to Hendricks, staring out the port beside me. "Well, what do you make of them now?" Before he could reply, Kincaide called out sharply. "Come here, sir! The charts are out of commission. We've gone blind." It was true. The charts were no more than twin rectangles of lambent red flame, with a yellow spark glowing dimly in the center of each, the fine black lines ruled in the surface showing clearly against the wavering red fire. "Mr. Hendricks!" I snapped. "Let's have your theory—reasonable or otherwise." Hendricks, his face pressed at an angle against one side of the port, turned toward me, and swung the shutter into place. Kincaide snapped on the lights. "It's no longer a theory, sir," he said in a choked, hushed voice, "although it's still unreasonable. These things—are eating us!" "Eating us?" Correy's voice joined Kincaide's and mine in the exclamation of amazement. He had just entered the navigating room in response to my order. "Eroding us, absorbing us—whatever you want to call it. There's one at work close enough to the port so that I could see it. It is feeding upon our hull as an electric arc feeds upon its electrodes!" "Farewell Ertak!" said Correy grimly. "Anything the rays can't lick—wins!" "Not yet!" I contradicted him.
