The thought that struck him first, with the force of a blow, was—“the tree I meant to climb is gone! Swept away by the sea!”

It was true. The tree, rotten at the roots, had vanished. Samatan had saved his life, and a new sense of respect for the aged native swept over Johnny. With it came the conviction that whatever it was the old native wanted from the professor, it must be right for him to have it. And something seemed to assure Johnny that he would hear the story without asking.

But at that moment, to talk at all was impossible. The shrieking of the wind, the cracking of branches, the roar of thunder and the mad tumult of the sea, were completely deafening. Johnny wondered how long it would last? Would greater waves come? Would he and Samatan at last be swept into the sea? To all these questions he found no answer.

In an effort to forget the terror of the situation he made himself think once more of the great steel ball and his adventures beneath the sea....

In the meantime his companions on the Sea Nymph were witnessing a feat such as even the gray-haired captain never had seen equaled. Watching the storm, yet fearing for the safety of Johnny and Samatan and hoping against hope that they might return, they on the yacht had delayed lifting anchor.

When at last they headed toward the narrow entrance of a natural harbor, the wind tore their sails to ribbons, while waves, mountain-high, swept them toward a rocky wall.

In despair, the captain trusted the fate of his ship to the native crew. Nor did he trust in vain. With a few yards of sail at their command the natives, in the midst of dashing spray, clung to spar and masthead, turning the graceful craft this way and that. Then—at precisely the right instant—they seemed to lift her from the sea and send her shooting through a channel so narrow it seemed the paint would be scraped from her two sides at once. They sent her gliding smoothly to safety, in a harbor as calm as a millpond.

“Bravo!” shouted the captain.

“Glorious!” the professor cried. “Never saw such sailing! Those men deserve all praise!”

Six long hours the storm roared on, and for six endless hours Johnny clung to his tree. Though the sea, like some menacing monster, appeared to thrust out long, white arms to grasp him, he remained safely with Samatan, in the tree top. At last, sweeping high overhead, the storm-clouds raced away—to leave a kindly, golden moon looking down on the boy and the old man.
