Smaltz already had slammed the receiver back on the hook. With a swift movement he threw in the switch and jumped for the outside. He dropped from the high platform and fell among the rocks some ten feet below. Instantly he scrambled to his feet and crouching, dodging among the boulders that strewed the river bank, he ran at top speed until he reached the sluice-boxes. The carpenter came out from his shop to take a leisurely survey of the world and Smaltz threw himself flat until he had turned inside again.

Then, still crouching, looking this way and that, watching the trail, he took a bottle from his pocket and pulling the cork with his teeth poured the contents over the mercury almost to the upper end of the first box. He went as far as he dared without being seen by Bruce inside the shed.

The pumps had already started and the big head of water was coming with a rush down the steep grade, but Smaltz had done his evil work thoroughly for wherever the mercury laid thickest it glittered with iridescent drops of kerosene.

He was thrusting the bottle back in his pocket, his tense expression relaxed, when he turned his head sharply at the sound of a crashing in the brush.

“Toy!” Smaltz looked startled—scared.

It was Toy, his skin a waxy yellow and his oblique eyes blazing with excitement and rage.

“I savvy you, Smaltz! I savvy you!” His voice was a shrill squawk. “I savvy you!” His fingers with their long, sharp nails were opening and shutting like claws.

Smaltz knew that he had seen him from the hill and, watching, had understood. It was too late to run, useless to evade, so he stood waiting while shrieking, screeching at every step, the Chinaman came on.

He flew at Smaltz’s face like a wild-cat, clawing, scratching, digging in his nails and screaming with every breath: “I savvy you! I savvy you!”

Smaltz warded him off without striking, trying to get his hand over his mouth; but in vain, and the Chinaman kept up his shrill accusing cry, “I savvy you, Smaltz! I savvy you!” There was little chance, however, of his being heard above the rush of the water through the sluice-boxes and the bumping and grinding together of the rocks and boulders that it carried down.
