Hilary acted swiftly. He caught the man's pistol arm, thrust it down sharply out of sight. A quick wrench, and the gun was in his own hand. The man, wild-eyed, opened his mouth to shout.

"Shut up," Hilary hissed fiercely. "Are you mad? You wouldn't have a chance. They'd ray us all clean out of existence." He thrust the pistol back into the man's blouse. "Wait; our chance will come."

"Oh, my God! Look!" someone screamed.

A command shattered the air; the tubes of the Mercutians uplifted; a blinding sheet of flame blazed solidly down the street. The minute's grace was up.


ven at this distance, the heat scorched and seared. There were many unfortunates caught farther down, men who had had no chance to seek safety in time. They melted in the furnace blast as though they were bits of metal in an electric arc.

"Run for your lives!" the shout went up. All thought of resistance was gone. It was every one for himself. The man with the gun was the first to run. Hilary found himself caught in the mad rush. The Mercutians were pounding along methodically raying in front of them.

Hilary was thrust into a little eddy of men to one side. It swirled and shoved. The entrance of the Pullman Building loomed ahead. The sight of it gave Hilary new vigor. That was his destination. If only he could make it.

He straightened out of his stoop, squared his shoulders. The next instant a human battering ram crashed through the twirling, yelling mob. Head down, right shoulder and elbow working in unison, a path magically opened where no path had been before. Every second was precious now. The heat of the tubes was engulfing him in waves, raising little blisters on the unprotected skin.
