all the dignity of the slave machine. It could wait. Painted scarlet on its nose was— CHICAGO There was a buzz of cheerfulness from the Russians as they got out of the open. Eight of their number here had died—two from sun, one from cold, one from suffocation, four all at once under the smash of a thousand-ton meteor. The mathematician amongst them sat down and began clumsy figures with his mitten-held pencil. A surveyor set up a transit. They were about to complete the orientation and construction of the rail tracks for Chicago. Angel supposed he would remain here under guard. But the captain had ideas. "You Yankees! There is rail material dumped in a small crater a few hundred yards from here. We have too few men as it is. You will begin the task of bringing them." The ground vibrated for an instant as a meteor struck above. Angel said, "Come on, Whittaker." They crawled back over the entrance bulwark and regained the still twilight of the outside. For a moment they stopped and adjusted the radio dials on each other's helmets. "I hope Boyd is all right," said Angel. "I hope we can find the place," said Whittaker. They turned and in great leaps began to scout for the incoming tracks of their ship. There were many such tracks and Angel had to take a quick orientation. Then they found theirs, neither older nor younger than any other tracks, and began to race back down it, taking broadjumps of forty feet with every step, trying to keep from sailing sky-high. The pumice was indifferent footing and clung to their duck shoes, leaving a slowly settling stream of particles in the half-light behind them. They had gone five miles before they saw anything on their backtrack. And then it was obvious that somebody in the work party had begun pursuit after missing them. The pursuit was specklike, unhurried as the weasel stalks. For who could find board and room on the Moon? Angel's breath was hurtful in his lungs.
