“What a monster,” he exclaimed. “What an inhuman monster! I wouldn’t have believed it possible.”

“Isn’t there something we can do?” Buckhart asked. “We just can’t stand here and let that fellow suffocate. Don’t you suppose there’s some way of finding the spring? Or we might tear down the wall.”

Though he spoke eagerly, there was not much conviction in his voice.

“By the time we’d found a way into the house the man would be dead,” Dick answered. “We couldn’t tear down the wall in time. No Randolph is the only one who can save him. He must be brought back; but how—how to do it?”

He was thinking rapidly. There must be way—some way. But there was so little time.

Suddenly he gave a quick exclamation.

“I’ve got it! By Jove, I’ve got it! Come along—quick! There isn’t a second to lose.”

He turned and flew toward the trail as fast as he could get over the ground, with Buckhart close at his heels. Into the car he sprang and started the engine.

“Never mind the lights!” he cried, as Brad hesitated. “Jump in—quick!”

The Texan leaped up beside him, and a moment later the Wizard was hitting the high places on Bonnet Trail, heading away from Denver.
