"Thank heaven, your're safe, Jean!" he shouted, and with reckless disregard of consequences he began to slide from the ledge toward her. "I thought you'd fallen down the precipice, when I pulled on the rope and found you not there!"

He landed on the beach at her feet. The tense look on his face faded as his eyes devoured her.

"Lord, girl, what ever made you do such a thing! I rushed back toward Skeleton Rib and met Kayak Bill coming this way. He let me down to the ledge—for I couldn't get down any other way. He's up there now waiting for us. Doggone you, anyway, you little rascal!"—he laughed shakily, grasping her by the shoulders,—"you nearly scared me to death!"

"But just see what I've found!" Jean opened her hand suddenly, and with the three nuggets lying on it raised it toward his eyes. Then without waiting for him to look at them, she thrust them into his hand and began to drag him toward the mouth of the cave.

Half an hour later two wild, troglodytic figures were giving vent to their joy by capering and dancing about the floor of the cavern.

"Jean, you've struck it rich! You've found the source of the gold of Kon Klayu!" Harlan shouted for the fifth time. "It's better than beach mining! It's better than Shane ever dreamed! I know enough to venture that this whole blessed little isle must have a base of igneous rock and the formation of this south end, especially, is impregnated with a network of gold-bearing dykes! Why, anyone could see that by the walls of this cave!" He bent, scooped up a handful of sand, and with eager, shining eyes watched while he spread it over his palm.

"Just imagine this hollow during one of our terrific sou'westers, Jean," he went on, looking about him. "The monster billows crashing into this cavern, rolling the boulders along the bottom, grinding them along this gold-bearing formation! By Jove, the action is the same as that in a stamp mill, almost! The gold is freed, becomes mixed with the sands, and sooner or later is carried out and concentrated along certain zones on the Island."

"But away goes all the mystery of our Island, too, Gregg!" Jean's voice carried a hint of regret. "That accounts for the strange, rolling sounds we used to hear during the storms, and for the giant balls of stone, and for everything!"

They filled their pockets with samples of the sand to take home to
Shane, and ascended to the ledge. From thence, with the assistance of
Kayak Bill and the rope they mounted one after the other to the top of
the precipice.

The old man listened to their story of the cavern in silence, though his eyes were glowing.
