He broke into an effortless trot, his boots padding lightly on the shining gray floor. "Three days," he thought. He forgot Max. He forgot Durval and the cats. He thought, "Three days," and a fine film of perspiration spread cold across his back. * * * * * "We have three days," Captain Elderburg said. He was a small neat man with a prim voice. His bland eyes peered forward into some middle distance, ignoring Scott. And Scott, sitting tautly in his chair, felt glad those eyes were not on him. "In three days," the Captain said, "or probably before, the _Kastil_ should find us. The _Kastil_--the best ship Inner-Planet Metals ever commissioned." Scott nodded. In the savage, free-for-all world of the space-miner, the _Kastil_ was known as the big ship, the new ship. The ship that could load its cargo hatches in a day, stuffing 100,000 tons of ore down in its belly for the hungering plants of Earth. "I've fought IP Metals for fifteen years," Elderburg said slowly. His eyes were very far away. "For fifteen years they've grown bigger and bigger, and the bigger they've got, the rougher they've played. You know their record, Scott. Murder, claim-jumping. What they can't steal with a blaster, they take by law." Glancing through the open port behind the Captain's head, out into the star-dappled dark of space, Scott asked: "Is there any way we can set up a permanent claim here on this asteroid without going back to Earth?" "You know better than that." Elderburg's eyes turned full on Scott. "Unless we bring a full cargo of reasonably purified ore to Earth, we can't lay claim to these mines, or to any other mineral rights here." His hands closed neatly, one inside the other. "And we've got to get a cargo back. This is our last chance. A strike as rich as this one will keep us going for a long time. But if we lose this claim to IPM, the days of the independent miner are over. Done with. We might as well sell the _Bertha_ and get out." "We'll be out of here in two days," Scott said eagerly. "If we...." "If," said Elderburg very plainly. His eyes turned away from Scott and his hands went all loose at once and spread out flat on the table. "If we cannot load in two days, Mister Jerill. If your cats that you so foolishly brought on board the _Bertha_ delay us so much that the _Kastil_ locates us. And beats us home with a load of ore. If that happens, Mister Jerill, I will see that you are black-listed from the rolls of every space flight unit now operating. You will be completely responsible for the failure of this cruise." Slumping back in his seat, he grinned maliciously at Scott. "I realize that our company was offering you a captain's position at the end of the expedition...." Scott stood up. Anger hammered powerfully at his temples. "All right. I admit I made a mistake. And I take full responsibility for my actions." "You must admit, Mister Jerill, that only a fool would bring an unknown space beast into a ship."
