Button-Bright did that, climbing the tree and then crawling out upon the limb until he was nearly over the gulf.

There he managed to fasten the strap, which reached to the ground below, and then he slid down it and was caught by the Wizard, who feared he might fall into the chasm.

Scraps was delighted.

She seized the lower end of the strap, and telling them all to get out of her way, she went back as far as the strap would reach and then made a sudden run toward the gulf.

Over the edge she swung, clinging to the strap until it had gone as far as its length permitted, when she let go and sailed gracefully through the air until she alighted upon the mountain just in front of them.
Almost instantly, as the great cone continued to whirl, she was sent flying against the next mountain in the rear, and that one had only turned halfway around when Scraps was sent flying to the next mountain behind it.
