with the intent to speak slightingly of the Professor's effort.

"Take it up stream throw it out, then let it float down," suggested
Ned.

Professor Zepplin did so, but the rope was found to be too short to
reach, and at Ned's direction, he made no further attempt.

Soon Ned heard some one shouting cheerily up the stream. It was Tad
Butler. He had dashed up to camp immediately upon reaching shore,
and the exercise restored his circulation. Walter, who was in camp
had Pink-eye ready and saddled for an emergency, and Tad mounting
the pony, forced him to take to the water. He was now returning to
rescue his brave friend, who was clinging to the rock. He had been
unwilling to trust the perilous trip to anyone else.

"I was afraid Walt would go over the falls, pony and all," he
explained, wheeling alongside Ned Rector and picking him up from the
rock.

"I'll run a foot race with you when we get ashore," laughed Tad.

"Go you," answered Ned promptly. "The one who loses has to get up
and cook the breakfast."
