"DOWN WITH CLARK! DOWN WITH THE TIN MEN! DEATH TO THE ROBOT LOVERS!" The furious mob was battering at the door now.

"Really, sir," Towney said, "you should leave here. They'll kill you if you don't!"

"Leave here? I should say not. I'll defy the fools. I'll tell them what I've done for them and make them understand." He glanced nervously at the door. "Besides there's only one door. I couldn't get away now."

"There's the time machine, sir."

"But isn't there some other way? Perhaps if you went out and talked to them...."

"You know there's no other way. Those people believe you've brought disaster to the human race and they mean to kill you. And if you don't hurry they will," Towney said urgently. "The time machine is set for twenty years in the future. Please hurry, sir!"

The door was beginning to give. Clark looked around unhappily and then walked to the time machine. "All right, I'll go. In the future I know the results of my work will be appreciated. I'll be a hero and benefactor of mankind."

Towney heard the door crash and roughly pushed his employer into the time machine as the mob burst through. "Push the starting button, push the starting button. Quick!" he screamed as the first of the mob reached him.

Clark's hand leaped to the control lever just as a brick crashed into his head. His hand completed its motion with more force than he had intended as he sank unconscious to the floor and the machine was set for a thousand years in the future instead of twenty.
