Steve Rush, picking up a pad of paper which he stuffed in his pocket, hurried from the office and started across the street on a run. As he did so he saw a red light burning dimly at the peak of one of the long row of soot-blackened mills that made up the plant of the Steelburgh mills, a signal indicating that a disaster of some sort had occurred in that building. Seeing that signal it was the duty of the Iron and Steel Police, who kept order in the mills, to report the fact to the accident department at once.

Steve did not need the red light to guide him. He was by this time familiar with the location of all the buildings, though there were some, such as the plate mills, where the armor plate was made for the ships of the Navy, which he had never entered. No one save those who were employed there were able to gain admission to the buildings where secret processes were employed.

Steve dashed by the guard at the gate.

"Here, where are you going?" demanded the guard.

"Accident department."

"Let me see your card!" demanded the officious gate guard.

"Some other time. Can't you see I am in a hurry?" answered the lad, running past the gate and into the yards at top speed.

The Iron and Steel Police like nothing better than an opportunity to show their authority. The result was that Steve had gotten but a short distance inside the yard when policemen, seeing him running, began shouting at him from all sides to halt. Perhaps they had seen him passing in and out, daily, for several weeks. But this made no difference. He was running, and all persons going faster than a walk must have a reason for so doing. It was their duty to stop the runner and learn what it meant. At least, that was the way these guardians of the mills construed their duty.

Steve merely pointed to the red light high up on number twenty-four, as the best answer to their questions. He kept on running. So did some of the policemen, but they were no match in speed, for the supple young fellow, who realizing the necessity for haste, kept on at top speed.

As he neared the building, three uniformed officers dodged out from behind a pile of steel bars, their attention having been called to the sprinter by the shouts of their companions.
