an air-lock entrance. He wondered what had caused the change, which had obviously been done at top speed. The last time he’d been here, not very long ago, the dome had still been intact, and there had been no hint of any impending move underground. The driver steered the car into the open air lock, and they waited until the first cargo truck had lumbered in after them. Then the outer door closed, the pumps were turned on, and in a minute the red light flashed over the inner door. Ebor removed the spacesuit gratefully, left it in the car, and walked clumsily through the inner door into the new base. A good job had been done on it, for all the speed. Rooms and corridors has been melted out of the rock, the floors had been carpeted, the walls painted, and the ceiling lined with light panels. All of the furnishings had been transferred here from the original dome, and the result looked, on the whole, quite livable. As livable as the dome had been, at least. But the base commander, Darquelnoy, waiting for his old friend Ebor near the inner door of the lock, looked anything but happy with the arrangement. At Ebor’s entrance he raised a limp tentacle in weary greeting and said, “Come in, my friend, come in. Tell me the new jokes from home. I could use some cheering up.” “None worth telling,” said Ebor.

He knew Darquelnoy well enough to know that the commander invariably overstated things. “What’ve they been up to, Dar?” he asked. “Come on, you can tell me over a hot cup of restno.” “I’ve been practically living on the stuff for the last two dren,” said Darquelnoy hopelessly. “Well, I suppose another cup won’t kill me. Come on to my quarters.” “I’ve worked up a fine thirst on the trip,” Ebor told him. The two walked down the long corridor together and Ebor said, “Well? What happened?” “They came here,” Darquelnoy told him simply. At Ebor’s shocked look, he rippled in wan amusement and said, “Oh, it wasn’t as bad as it might have been, I suppose. It was just that we had to rush around so frantically, unloading and dismantling the
