"That's just about right. The first week we were in operation we kept wondering why we had to travel farther every day to get to the dredges. Then we realized that solid ground on Venus isn't solid ground at all. It's just big chunks of denser stuff that floats on top of the mud like dumplings in a stew. But that was nothing compared to the other things—"

They had reached the vicinity of the salvage operation on Number Five dredge. To Kielland it looked like a huge cylinder-type vacuum cleaner with a number of flexible hoses sprouting from the top. The whole machine was three-quarters submerged in clinging mud. Off to the right a derrick floated hub-deep in slime; grapplers from it were clinging to the dredge and the derrick was heaving and splashing like a trapped hippopotamus. All about the submerged machine were Mud-pups, working like strange little beavers as the man supervising the operation wiped mud from his face and carried on a running line of shouts, curses, whistles and squeaks.

Suddenly one of the Mud-pups saw the newcomers. He let out a squeal, dropped his line in the mud and bounced up to the surface, dancing like a dervish on his broad webbed feet as he stared in unabashed curiosity. A dozen more followed his lead, squirming up and staring, shaking gobs of mud from their fur.

"No, no!" the man supervising the operation screamed. "Pull, you idiots. Come back here! Watch out—"

The derrick wobbled and let out a whine as steel cable sizzled out. Confused, the Mud-pups tore themselves away from the newcomers and turned back to their lines, but it was too late. Number Five dredge trembled, with a wet sucking sound, and settled back into the mud, blub—blub—blub.

The supervisor crawled down from his platform and sloshed across to where Simpson and Kielland were standing. He looked like a man who had suffered the torment of the damned for twenty minutes too long. "No more!" he screamed in Simpson's face. "That's all. I'm through. I'll pick up my pay any time you get it ready, and I'll finish off my contract at home, but I'm through here. One solid week I work to teach these idiots what I want them to do, and you have to come along at the one moment all week when I really need their concentration." He glared, his face purple. "Concentration! I should hope for so much! You got to have a brain to have concentration—"

"Barton, this is Kielland. He's here from the Home Office, to solve all our problems."

"You mean he brought us an evacuation ship?"

"No, he's going to tell us how to make this Installation pay. Right, Kielland?" Simpson's grin was something to see.

Kielland scowled. "What are you going to do with the dredge—just leave it there?" he asked angrily.
