The clamor all around them was just as boisterous as ever, for certainly nothing had occurred to tone it down. The citizens, facing complete destruction for their town, were hoarse with shouting; but their main thought now was to make sure of the safety of the women and children, who could be seen fleeing through most of the streets, awed by the terrible nature of the calamity.

Nevertheless, none of those who watched Ralph and Rob paid the least attention to these outside occurrences. The fire might roar, and the populace shriek in terror, but just then their undivided attention was given to the little drama being unfolded before their eyes.

Ah! Ralph no longer pushed on. Whether he had reached the end of his wire coil, or believed that it was useless to cover more ground did not matter. What did count was the fact that he and Rob were feverishly attaching the battery and switch to the wires, showing that they intended to test their hastily arranged programme without further delay.

“Oh! hurry, hurry, please!” groaned Tubby, speaking to himself, of course, but in so doing voicing the feeling that held sway in every heart; for the building was rapidly being clutched in the ever extending fingers of the fire, and would soon be such a mass of flames that to wreck it might do more harm than good.

“It’s all ready!” whooped Sim, as he saw by the actions of the two boys that they had succeeded in making the attachments.

Then Ralph pushed Rob forward. It could be seen that he meant to force the scout leader to press the button that would complete the work. Even in that dreadful moment Ralph did not forget that it had been Rob’s brilliant idea, after all, and to his chivalrous mind it seemed only right and proper that Rob’s hand should be the one by means of which Wyoming might be saved.

Rob did not hesitate. This was no time for expostulation. He proceeded to do as the other urged him. Those who stood by held their breath with awe, watching the old deserted factory the while, as though everything depended on the result of Ralph’s efforts.

They saw the building give a distinct shiver. Then the very earth under them actually rocked as if an earthquake had taken place. Tubby was thrown down, and the rest had more or less difficulty in keeping on their feet, such was the concussion of air as the dynamite went off.

They also heard a heavy roar, and then, wonder of wonders, the old building seemed to collapse, to fall down like a house made of cards. There was a horrible series of crashing sounds; some remnants even fell close by the boys, though luckily none of them received the slightest injury. Then, as the smoke shifted and the dust clouds settled, they saw a great gap where the deserted factory had stood.

The Fire Chief was awake to the possibility of the debris presenting a new peril. He immediately gave orders to the three men to make their way forward, and if the hose were still in condition for use to turn the nozzle toward the wreck.
