Boone paused, with a grim chuckle. As Lightfoot gained his side, the veteran said:

"Look up—what do you see?"

The Kickapoo obeyed. Far above his head shone a faint light, partially intercepted by gently waving leaves. A dimly twinkling star told him the truth. Then a cloud shot over this gleam.

"Fix yourself for a tough climb, chief. It's up the inside of a tree we must go. You'll need all your hands and feet," cried Boone, securing his rifle upon his back.

Lightfoot now understood all. Boone had not sought shelter in the cave without knowing how he was to get out of it. And yet this den had often been explored by himself. How had he missed noting this strange passage?

Easily explained. A month or more previously Boone had shot a wild-turkey as it sat upon the tree. It lodged, and, aided by the thickly-clustering grape-vines that shrouded the gnarled trunk, he ascended for his game. It had fallen into the hollow. Aided by a supple vine, he descended into the shell. The bottom gave way beneath his feet, precipitating him into the cave. Thus the discovery was made that was now to open to them the road to freedom once more.

Carefully feeling around, Boone soon secured the severed end of the grape-vine, and then began the ascent. This was difficult, since the hollow of the tree was barely large enough to admit the passage of a human body, and little assistance could be given by the feet, since the knees could only be bent a trifle.

Still, though age and sorrow had sapped his strength, the Wood King raised himself to the top of the trunk, where he clung, panting and exhausted, shaking the vine as a signal to Lightfoot. As the vine tightened Boone peered keenly downward.

Though the tree-top had been broken off at some thirty feet from the ground, its limbs were still vigorous, rising far above the stub, thickly covered with leaves and twigs. Parting them, Boone gazed downward and around, as well as the increasing gloom would permit.

The hill was nearly bare of trees, with but scant underbrush, a notable exception to the larger hills that rose around, in this respect, since they were densely wooded.
