"And he most certainly will," interrupted Tad, advancing a step.

"I protest!" shouted the Professor. "You yourself should go, Lige. You are——"

"I am needed right here, sir," replied the guide, shortly. "You'd have both of us at the bottom if I left it to you to take care of this end."

"I'm ready, sir when you are," reminded Tad.

The guide, without further delay, and giving no heed to Professor Zepplin's nervous protests, slipped the noose over Tad's shoulders, and, drawing it down and up under his arms, secured the knot so that the loop might not tighten under the weight of the boy's body.

"Now, be very careful. Make no sudden moves. And, if you meet with anything unlooked for, let me know at once. You know, you will have to stay down there while we are drawing the boy up. But, before removing the rope from your own body, make sure that you are safe. If you find the support too weak to bear your weight, let me know. I'll send down another rope to which you can tie yourself until we get Master Walter to the top. Be sure to fasten him securely to the loop before you give the signal to haul up," warned the guide. "Here, put my gun in your pocket."

"I understand."

"Are you ready?"

"Yes."

Tad tossed away his sombrero and sat down on a shelf of rock at the edge of the cliff, his feet dangling over.
