Larkin was uncoiling the whip from his belt. He strode toward the fast-deepening ditch. He selected a subject. "You—fella. You're lazy, huh? You like to gold-brick it? Then see how you like this!" He laid the whip across the green shoulders of the Martian.

The Martian winced. He raised an arm to shield off the whip. Again it curled against his flesh. He whimpered. His grin was stark, inquiring.

"Hit that shovel, you green bastard!" Larkin roared.

The Martian understood. So did the other Martians. Their muscles quivered as they drove into their work.

Larkin came back, smiling—almost dreamily, Smith thought. Cleve said, "Excellent. I'd hardly hoped for such conformity. Hardly expected it."

"You mean," Smith asked, "that this little scene can be projected from a dozen to a hundred? From a hundred to a thousand—?"

"From this little plot to the whole, surface of the planet," Cleve said. "The mass is nothing more than a collection of individuals. Control the individual and you've got the mob. That is if you follow through with the original method. Set the hard pattern."
