feet to the tree. We will use you for an anchor."

In a trice the Professor's feet were made fast to the tree with the
remaining piece of rope that had broken off short.

"Down on your stomach, Eagle-eye!" commanded the resourceful Ned,
giving the redskin a jerk that sent him sprawling. "Take hold of his
ankles and hang on, Professor. You next, Walter. Good. Now grab me
by the ankles, while I go over head first."

But Ned's carefully laid plans failed. The human chain was not long
enough to reach.

"Pull back, quick!" he ordered.

The return, however, was less easily executed, and perspiring, weak
and trembling, Ned finally succeeded in scrambling to the cliff, with
the aid of those behind him.

"What can we do now?" begged the Professor, greatly agitated.

"Try it another way, that's all. We've simply got to do it. Sit down
and brace your feet against that boulder near the edge, there,
Professor."

This Professor Zepplin did quickly. Walter dropped down in front of
him, and next came the Shawnee and Ned Rector, each, save the
Professor, sitting on his knees, facing the edge of the cliff.

"Now each one grab the ankles of the one ahead of him," directed Ned.
