"They got what was coming to them for trying to resist our sky ships," Joe Buckner said.

"Oh, yes, they deserved their fate." The instructor hitched the Thor gun a little higher on his hip.

Billy Kasker was silent.

"We will go next to the fields, then to the factory section—such of as there is—then to that part of the city which we have allowed the natives to rebuild. Come."

The class moved out of the city. Here they saw their first natives. Clad mostly in rags—many of them bent and stooped, some of them showing the marks of hunger—they were a quiet people who kept strictly out of the way of the class group. But except for the clothing and the marks of hunger, they were identical in appearance with their conquerors.

"Why, they look just like us!" Joe Buckner said indignantly. He sounded outraged at the resemblance.

"There are many differences," the instructor said quickly. "Note their clothing, how poorly made it is. They make it themselves out of the wool of some kind of animal—deer, I believe, or bear."

"Sheep," Billy Kasker corrected.

"Oh, yes, sheep is the name of the animal. Thank you, Billy."

"You're welcome, sir."
