CHAPTER XXV.
THROUGH THE FLUME.

Faster than he had ever travelled before in his life Nat was hurtled along down the flume. Water dashed upward into his face, half choking him and occasionally his board would hit the wooden side with a bump that almost threw him off. His knuckles were bruised and bleeding and his head dizzy from the motion. It was the wildest ride that the lad, or any other lad for that matter, had ever undertaken.

Suddenly, ahead of him—above the noise of the rushing water—came another sound, a deep-throated, sullen thunder. As he shot along with the speed of a projectile, Nat realized what the strange sound betokened. The end of the flume. Cal had told them that the raised water-course discharged its contents into a big pool at that point. With a sudden sinking of the heart Nat realized that he had forgotten to inquire how high the drop was. If it was very high—or if there was but little water in the pool below the flume—he would be dashed to pieces, or injured so that he could not swim, and thus drown.

But even as the alarming thought was in his mind, Nat felt himself shot outward into space. Instinctively his hands came together and he dived downward, entering the water about twenty feet below him, with a clean dive.

For a space the waters closed above the lad's head and he was lost to view in the moonlit pool. When he came to the surface, out of breath and bruised, but otherwise uninjured, he saw that he was in what had formerly been used as a "collection-pool" for the logs from the forest above. He struck out for the shore at once and presently emerged upon the bank. But as he clambered out, the figure of a Chinaman who had been seated fishing on the brink galvanized into sudden life. The Mongolian was poaching in private waters under cover of the darkness and was naturally startled out of a year's growth at the sudden apparition.

With an ear-splitting screech the Mongolian leaped about three feet into the air as if propelled by a spring, and then, with his stumpy legs going under him like twin piston rods, he made tracks for the town.

"Bad spill-it! Bad spill-it! He come catchee me!" he howled at the top of his voice, tearing along.

As he dashed into the town a tall man dressed in Western style, and with a determined, clean-cut face under his broad-brimmed sombrero, stepped out of the lighted interior of the post-office, where the mail for the early stage was being sorted.

"Here, Sing Lee," he demanded, catching the astonished Chinaman by the shoulder and swinging him around, "what's the matter with you?"

"Wasee malla me, Missa Sheliff? Me tellee you number one chop quickee timee. Me fish down by old lumbel yard and me see spill-it come flum watel!"
