"Oh, yes; that's easy. When they shake their hand, it means you want to go up or down," exclaimed the lad enthusiastically.
"O Chunky, you're hopeless. No, no! Nothing of the kind. Listen.
When I move my hand up and down, just like this—Understand?"
"Sure."
"That means I want to go down further. They don't wave their hands at all, at least I hope they don't while I am hanging in the air. Now, do you think you understand?"
"Yes, I understand."
"Repeat the directions to me then, please."
Stacy did so.
"That's right. See that you don't forget. Remember, I'm depending upon you, Chunky, and if you fail me, I may be killed."
"Don't you worry about me, Tad," answered Stacy, swelling with pride because of the responsibility that had been placed upon his plump shoulders. "I can make motions as well as anybody. Eagle-eye, tend to business over there. Get hold of that rope. Twist it around your arm. There, that's right."
"Hear, hear!" cried the boys.
