The night resolved itself into a weird phantasmagoric nightmare for me, a gigantic game of hide-and-seek, in which I was "it." Gasping, choking, flung to earth and stunned by ear-shattering explosions, staggering up somehow, ducking to avoid being crushed beneath the ponderous treads of metal monsters that plunged uncannily for me, sobbing aloud in terror, swerving just in time from in front of a swinging crane, instinctively side-stepping just as a pale violet ray swept into nothingness all before it--I must have been delirious, for I retain only the vaguest memory of the horror. And all the time the guiding search-rays biased down upon the torn and shattered fields, and the disintegrator, unnoticed in the vast uproar, steadily kept up its deadly work. At last, in my delirium and terror, I heard a great rending and tearing. I looked up, and a tractor just missed me as it rolled by on swishing treads. But that one glance was enough. The ice cap was moving, flowing forward, a thousand-foot wall of ice! Great billowing clouds of steam spurted from innumerable cracks. The deed had been done! The world was saved for mankind! Summoning the last ounce of strength, I set off on a steady run for the shelter of the rock cave, to be out of the way when the final smash-up came. * * * * * I was not pursued. The ponderous machines, thousands of them, were hastily forming into solid ranks directly in front of the tottering glacier wall. The master machine had seen its impending fate in the visors, and was organizing a defense. Even in my elation, I could not but feel unwilling admiration for this monstrous thing of metal and quartz, imbued with an intelligence that could think more coolly and quickly than most humans. Yet I did not stop running until I reached the cave. My heart gave a great bound. For there, peering anxiously with worn face into the growing dawn, stood the figure of Keston--my friend whom I had never expected to see alive again. "Meron!" he shouted. "Is it you--or your ghost?" "The very question I was about to ask you," I parried. "But look, old friend: see what your genius has accomplished--and is now destroying." The mountain of ice was flowing forward, gathering speed on the way. At an invisible signal, the massed machines--thousands on thousands of them--started into action. Like shock troops in a last desperate assault they ground forward, a serried line that exactly paralleled the threatened break, and hundreds deep. This old earth of ours had never witnessed so awe-inspiring a sight. They smashed into that moving wall of ice with the force of uncounted millions of tons. We could hear the groaning and straining of furiously turning machinery as they heaved. Keston and I looked at each other in amazement. The master machine was trying to hold back the mighty Glacier by the sheer power of its cohorts! * * * * *
