Rip crossed the room and snapped off the switch which opened the wire for broadcasting. While Ali, with Dane's help, quietly and effectively immobilized the Eysies with their own belts. "There should be at least three men here," Rip waited by the door. "We have to get them all under control before we start work." However, the interior of the bubble, extending as it did on levels beneath the outer crust of the asteroid, was not an easy place to search. An enemy, warned of the invasion, could easily keep ahead of the party from the Queen, spying on them at his leisure or preparing traps for them. In the end, afraid of wasting time, they contented themselves with locking the doors of the corridor leading to the lower levels, making ready to raid the storeroom they had discovered during their search. Emergency hydro supplies consisted mainly of algae which could be stored in tanks and hastily put to use--as the plants now in the Queen took much longer to grow even under forcing methods. Dane volunteered to remain inside the E-Stat and assemble the necessary containers at the air lock while the other two, having had more experience, went back to the spacer to strip the hydro and prepare to switch contents. But, when Rip and Ali left, the younger Cargo-apprentice began to find the bubble a haunted place. He took the sealed containers out of their storage racks, stood them on a small hand truck, and pushed them to the foot of the stairs, up which he then climbed carrying two of the cylinders at a time. The swish of the air current through the narrow corridors made a constant murmur of sound, but he found himself listening for something else, for a footfall other than his own, for the betraying rasp of clothing against a wall--for even a whisper of voice. And time and time again he paused suddenly to listen--sure that the faintest hint of such a sound had reached his ears. He had a dozen containers lined up when the welcome signal reached him by the com-unit of his field helmet. To transfer the cylinders to the lock, get out, and then open the outer door, did not take long. But as he waited he still listened for a sound which did not come--the notice, that someone besides himself was free to move about the Stat. Not knowing just how many of the supply tins were needed, he worked on transferring all there were in the storage racks to the upper corridor and the lock. But he still had half a dozen left to pass through when Rip sent a message that he was coming in. Out of his pressure suit, the Astrogator-apprentice stepped lightly into the corridor, looked at the array of containers and shook his head. "We don't need all those. No, leave them--" he added as Dane, with a sigh, started to pick up two for a return trip. "There's something more important just now--" He turned into the side hall which led to the com room.
