That brought a grin from the negro. He showed his teeth, and shook his fist at Harry; but Jim knew his meaning well enough. The big fellow was just like the rest of his people—just a big, strong, healthy baby, who saw the fun in everything, and, if there were no fun, manufactured it promptly.

"I's gwine to break yo into little pieces," he said, clambering on to the cab and poking his face within an inch of Harry's. "Yo say I hab hard head? Lummy! Me hab hard fist as well."

"Git out!" shouted Harry, striking at him with the slack end of the rope that commanded the bucket trigger.

"Who's he?" demanded Joe, nodding at Jim, and suddenly changing the conversation.

"Him? Why, Jim, of course. Saved Mr. Barton."

"Den I knows him."

To Jim's astonishment the negro stretched out a hand and shook his eagerly. Then he explained the situation. "Know Tom and Sam," he said. "Dey down here now, seein' tings. I show dem round. Tom mighty impressed: he tink yo work de digger better'n Harry."

That brought an exclamation from the latter, while Joe jumped down from the machine just in time to escape the swing of the rope. But his words were true; close beside the digger were Tom and Sam.

"By de poker, but yo run him well!" shouted Tom. "Me's watched yo dis last half-hour. Seems to Tom as ef yo soon have a job in the diggin'."

To the huge fellow everything that Jim did was well done, everything he attempted was sure to be accomplished; and never for one moment did he tire of watching his hero. But Jim had his lesson to learn, and for another hour held to the work. By that time he had filled a whole spoil train, and had watched another shunted into position.
