"But I don't want to fall," wailed the boy.

"Oh, very well, then, stay where you are," retorted Ned.

"I will help you down, Stacy," offered Tad, riding under his companion. "Now, let go."

"I—I'm afraid."

Tad grabbed the fat boy's legs, giving them a violent tug, whereupon Stacy and the vine came tumbling down. In trying to catch Chunky, Tad Butler was himself unhorsed, and the two boys landed on their heads and shoulders on the soft ground with the yells of their companions ringing in their ears.

"Get up!" commanded the Professor sternly. "This sort of thing has gone far enough."

"Tha—that's what I say," stammered Chunky, wiping the muck from his flushed face. "A good old-fashioned country road is good enough for me. I don't like this kind of traveling."

"Do you want to be sent back?" demanded Professor Zepplin grimly.

"No-o-o-o," drawled Stacy. "Not if I have to go back over that trail. That's the stickiest mess I ever got into."

"Your behavior is somewhat sticky, too," observed the Professor, with a smile. "Now, if there is no objection, I move that we proceed on our journey, but I wish Master Stacy to ride just ahead of me so that I may watch him."
