Munro, without stopping to ask why, bent his great strength to the task; and it was a task, for in his hose the pressure of the water was tremendous. It spurted back all over him, and at the last the nozzle was fairly blown away from him.

"Now couple my hose to yours quick, quick, before my hose fills!" cried
Keith.

"They won't go—" Munro began to object.

"Yes, they will, mine's a special thread," urged Keith, who had remembered Bert Taylor's reversed nozzle.

All three bent their energies to catching the threads. It was a fearful job, for the strength of the water had first to be overcome. Keith was terribly excited. Time was precious, for not only might the roof give way beneath them, but at any moment the water might come again in Keith's hose. Then it would be physically impossible to make the coupling. All three men concentrated their efforts on it, their feet gripping the irregularities of the roof or slipping on the shingles. Frank Munro bent his enormous back to the task, the veins standing out in his temples, his face turning purple with the effort. Keith helped him as well as he was able. Talbot Ward, coolly, deliberately, delicately, as though he had all the time in the world, manipulated the coupling, feeling gingerly for the thread. The water spurted, fanned, sprayed, escaping with violence, first at one point, then at another, drenching and blinding them.

"There!" breathed Ward at last, and with a few twists, of his sinewy hands brought the couplings into close connection. Munro relaxed, drawing two or three deep breaths. Without the aid of his great strength the task could not have been accomplished.

"Hook her over the chimney," gasped Keith.

With some difficulty they lifted the loop of the throbbing hose over the chimney.

"Down we go!" cried Keith, and slid hand over hand down the way thus made for them. The others immediately followed, and all three stood looking back. It was a wonder the building had stood so long, for in both stories it was afire, and the walls had apparently burned quite through. Indeed, a moment later the whole structure collapsed. A fountain of sparks and brands sprang upward in the mighty suction.

"There goes our good hose!" said Keith.
