Potterboy and Grisby followed suit, staring off into the approaching dusk at the one big stumbling block which had prevented them from resurrecting Mars. * * * * * The humans had left. All traces of their coming had been obliterated by the sea of restless sand, except one thing--a spherical deuterium water-container; which, during the windy season, would be buffeted about the planet this way and that, the law of averages occasionally causing it to crack into the timeless Martian wall. At such times, the Cones would philosophically contemplate it and the peculiar, yet likeable, creatures that had brought it. One Cone, who was considered a little strange by his brothers because he lacked the philosophic intensity for complete introverted contemplation, one day, broke the telepathic silence; a thing considered still stranger by his brothers, since it was thought very rude to disturb one another, except in times of extreme importance. _“A shame we could not communicate ... strain incurred destroying furnaces ... thousands of years to erase ...”_ Weakened by many buffetings, the water sphere hit the wall for the last time. With a crack it split in half, splashing gallons of water far up the wall. The nearest Cones shrieked in telepathic unison as the Life-Destroyer splashed nearby! Almost immediately, directed by the urgency of their commands, their organic-robots--the Blotting Pads--were hurling themselves upon the death giving liquid! The Cones, at the height of their evolutionary ascent, one by one, returned to the contemplation of eternity. Once and for all time, the danger was past.
