Natt Roberts brought his eyes up from his camera viewer. "I've got most of what we'll need for a while, sir."

Plekhanov turned back to Chessman. "We might as well head for their principal city, the one with the pyramids. We'll make initial contact there. I like the suggestion of surplus labor available."

"Surplus labor?" Chessman said, setting the controls. "How do you know?"

"Pyramids," Plekhanov rumbled. "I've always been of the opinion that such projects as pyramids, whether they be in Yucatan or Egypt, are make-work affairs. A priesthood, or other ruling clique, keeping its people busy and hence out of mischief."

Chessman adjusted a speed lever and settled back. "I can see their point."

"But I don't agree with it," Plekhanov said ponderously. "A society that builds pyramids is a static one. For that matter any society that resorts to make-work projects to busy its citizenry has something basically wrong."

Joe Chessman said sourly, "I wasn't supporting the idea, just understanding the view of the priesthoods. They'd made a nice thing for themselves and didn't want to see anything happen to it. It's not the only time a group in the saddle has held up progress for the sake of remaining there. Priests, slave-owners, feudalistic barons, or bureaucrats of a twentieth-century police state, a ruling clique will never give up power without pressure."

Barry Watson leaned forward and pointed down and to the right. "There's the river," he said. "And there's their capital city."

The small spacecraft settled at decreasing speed.
