blurred and unreal. But in a moment I was used to it, my mind translating its distortion into the terms of its reality. A dark abyss was under us here as we poised. Ahead, a thousand feet away now, the ridge was visible. A cliff was at one side of it, a honeycombed, submarine wall, a peak of which rose above the surface as a volcanic little island, with a tiny crater mouth, yawning faintly yellow from the fires of the earth which here must be close. The slow-moving, struggling little line of submarine vehicles was just mounting to the ridge. Only a few miles from here and they would be under the city of Arron. We must turn them back here. Slowly we approached, still out of Tollgamo's range. We had long since been seen, of course. The waving headlights of the ten huge black vessels turned our way. Monsters with searching, glaring eyes. And then a tentative shot came. In the blurred watery twilight it was a stab of thin violet light. Not instantaneous, but slow-moving as though for a second it was pushing its way at us. But it blurred to nothingness far short of us; and in a few seconds it died. At Peters' signal we divided now, spreading fanshape between the leading Tollgamo ship and Arron; skimming close under the surface, still keeping three hundred feet or more away from the leading vessel. But we had to get within fifty feet for our rays to be effective! I could feel my heart pounding, and my blood seemed cold. And then a puff of orange light from the bow of Peters' cylinder gave the signal for our first attack. Beside me I could hear Allen suck in his breath. My hands were on the small gun-firing mechanisms—my two small ray projectors on one side of the cylinder, Allen's on the other, with Leh's ranging in a quadrant of the bow and stern. In a slanting dive, we plunged forward and down. It was a chaos of blurred confusion to me, that first slanting plunge that took us close past the looming black side of one of the Tollgamo vessels, half circling it until in a few seconds we had fired our six little stabbing bolts and were past, rising again. I was aware that all the area of water suddenly seemed churned into silver phosphorescence through which shapes were diving. A bolt stabbed at us and missed. Then as we were mounting, one caught us. For a second it clung, with a bubbling red viscosity of fusing metal, glaring against my small bullseye pane. Would it eat through? Undoubtedly, if it clung too long, or if another were to strike in the same place.
