Feet slapping against the mud, they went about five miles from the Hazeltyne station, swimming easily across ponds too broad to jump. The mud, if not precisely as pleasant to the touch as chinchilla fur, was not at all uncomfortable, and the dripping air caressed their skins like a summer breeze back on Earth. Tiny, slippery creatures skidded and splashed out of their way. Finally Kershaw stopped. His experienced eye had seen a trail of swamp weeds crushed low into the mud.
"Keep your eyes open," Kershaw said. "There's a Slider been around here lately. If you see something like an express train headed our way, start shooting."
At each leap along the trail they peered quickly around. They saw no Sliders, but this meant little, for the beasts lived under the mud as much as on top of it.
Kershaw halted again when they came to a roughly circular area some ten yards in diameter where the weeds had been torn out and lay rotting in the muck.
"We're in luck," he said as Asa skidded to a stop at his side. "An egg was laid somewhere here within the last week. These places are hard to spot when the new weeds start growing."
Kershaw took a long look around.
"No trouble in sight. We dig."
They started at the center of the cleared area, shoveling up great gobs of mud with their hands and flinging them out of the clearing. Usually a muck man dug in a spiral out from the center, but Graybar and Kershaw dug in gradually widening semi-circles opposite each other. They had to dig four feet deep, and it was slow going until they had a pit big enough to stand in. Each handful of mud had to be squeezed gently before it was thrown away, to make sure it didn't conceal an egg. As he worked, Asa kept thinking what an inefficient system it was. Everything about the operation was wrong.
"Got it!" Kershaw shouted. He leaped out of the pit and started wiping slime off a round object the size of a baseball. Asa jumped out to watch.
"A big one," Kershaw said. He held it, still smeared with traces of mud, lovingly to his cheek, and then lifted it to eye level. "Just look at it."
