"Right," said Rawson tersely. "But, man, what have you done with the drill? It's smeared over with gold!"

"Fair clogged wid it, sir," Riley's voice betrayed his own excitement. "You remimber we couldn't pull it at first—the drill was jammed-like after it bruk through at the ten-mile livil. Then it come free—and luk at it! Luk at the damn thing! Sent down for honest work, it was, and it comes back all dressed up in jewelry like a squaw Indian whin there's oil struck on the reservation! Or is it gold ye were after all the time?" he demanded.

"Gold! Gold!" a hundred voices were shouting. Dean hardly heard the voice of the foreman, made suddenly garrulous with excitement. He stared at the big drill head, heaped high with the precious metal. It was jammed into the diamond-studded face of the drill; it filled every crack and crevice, a smooth, solid mass on top of the head and against the stem. A workman had brought a singlejack and chisel; he was prying at a ribbon of the yellow stuff. Riley went for him, gun in hand.

"L'ave it be!" he shouted.

"But, confound it all, Dean," Smithy's voice was saying in a tone of disgust, "I thought we were working on a power plant. Not that a gold mine is so bad; but we can't work it—we can't go down after it at ten miles."

"Gold mine!" Rawson echoed. "I'll say it's a gold mine—but not because of the gold. Do you notice anything peculiar about that, Smithy?"

His assistant replied with a quick exclamation:

"You're right, Dean! I knew there was something haywire with that. Solid chunk—been cast around that stem—melted on. And that means—"

"Heat," said Rawson. "It means we've found what we're after. Give the gold to the men; tell them we'll divide it evenly among them. There's more down there, but there's something better: there's energy, power!"

He snapped out quick orders. "Get the temperature. Drop a recording pyrometer. Let me know at once. There'll be plenty doing now!"
