“Here, spread your arms and take my place in line,” he snapped out suddenly to Merritt.

The next instant his lithe young figure darted across the flame-lit open space in front of the school. He knew the interior of the old building like a book, and that would aid him in the task he had steeled himself to perform. He rushed up to the group about the shrieking woman.

“What room is your child in?” he cried, his heart seeming to rise in his throat and choke back the words.

“That one on the south corner,” cried the woman mechanically, staring at him with frightened eyes. “See, the flames are getting nearer to it! Oh, my baby! My baby!”

She gave a terrible scream and sank back. Had they not caught her she would have fallen. When she opened her eyes again there was a roar all about her that was not the roar of the flames.

It was the tremendous, awe-stricken turmoil of the crowd. They had seen a boyish figure dart from the fainting woman’s side, shake off a dozen detaining hands, and then, wrapping his coat about his head, dash by a back entrance into the burning building.

As he flung open the door and vanished, a great puff of smoke rolled out. The cry of awed admiration for such bravery changed to a groan of despair,—the terrible voice of massed human beings seeing a lad go to his death. For, as the flames crackled upward more relentlessly than before, it did not seem within the bounds of possibility that anyone could enter the place and emerge alive.

CHAPTER XI.
THE FIRE TEST.

Touched with reckless bravery, foolhardiness in fact, as Rob’s act had appeared to be, yet he had not acted without taking due thought. As always in emergencies, his mind worked with great swiftness. He had no sooner made up his mind that it was his duty, cost what it might, to save that innocent little one’s life, than he had hit upon a plan.

If the child was lodged in the center of the building, he knew full well that long before its life must have been yielded up to the fire demon. But if the quarters of the janitor were, as he believed, in the south corner of the school, then there was still a chance. The mother’s words had put him out of all doubt on this score and Rob instantly determined to face the most daring act of his life.
