The end of the big tube was not far away. Remfry could tell that, for its oscillations were growing shorter and more violent. The part conquered lay quiet behind him. But somewhere in the smoke in front the metal pipe was brandishing like the snapper of a whip-lash.

With lightning suddenness down it smashed on the hose not three inches before his fingers. Had it struck his hand, it would have splintered every bone. The polished brass glinted as it gyrated wildly away. The next few feet would be the most perilous, for at any second the nozzle might crack his skull.

The hot black smoke puffed along the ground· Remfry butted blindly into it, lowering his face, till his lips brushed the dirt. Inch after inch of hard round tube slipped back under him and grew quiet. With eyes closed tight he wriggled on. When he was within a yard of the pipe, he knew it would stop slatting.

The moment came sooner than he had expected. With one final flirt the nozzle gave up, conquered, and the jet began to furrow the chips and dirt. A second later Remfry’s fingers touched the brass handles.

Soon Penfield was beside him, his strength and consciousness fully restored; and they took up once more their battle with the flames.

It was well toward morning before the fire was out, and the two started for home. Remfry felt better. The city was safe. Still the thousands of dollars’ worth of lumber that had gone up in smoke hung, a black, heavy pall, above his conscience. He dreaded to meet Jack and Billy.

As he stumbled on, a sentence from a passer-by caught his ear:

“Started by a rocket from Triangle Hill, across the river.”

He gripped the man’s arm.

“Are you sure?” he almost shouted.
