"Since we seem to be more ornamental than useful on this job, you might give me another lesson in Red Butte geography, Mac," he said, purposely changing the subject. "Where are the gulch mines?"

The trainmaster explained painstakingly, squatting to trace a rude map in the sand at the track-side. Hereaway, twelve miles to the westward, lay Little Butte, where the line swept a great curve to the north and so continued on to Red Butte. Along the northward stretch, and in the foot-hills of the Little Timanyonis, were the placers, most of them productive, but none of them rich enough to stimulate a rush.

Here, where the river made a quick turn, was the butte from which the station of Little Butte took its name—the superintendent might see its wooded summit rising above the lower hills intervening. It was a long, narrow ridge, more like a hogback than a true mountain, and it held a silver mine, Flemister's, which was a moderately heavy shipper. The vein had been followed completely through the ridge, and the spur track in the eastern gulch, which had originally served it, had been abandoned and a new spur built up along the western foot of the butte, with a main line connection at Little Butte. Up here, ten miles above Little Butte, was a bauxite mine, with a spur; and here....

McCloskey went on, industriously drawing lines in the sand, and Lidgerwood sat on a cross-tie end and conned his lesson. Below the siding the big crane was heaving the derailed cars into line with methodical precision, but now it was Gridley's shop foreman who was giving the orders. The master-mechanic had gone aside to hold converse with a man who had driven up in a buckboard, coming from the direction in which Little Butte lay.

"Goodloe told me the wreck-wagons were here, and I thought you would probably be along," the buckboard driver was saying. "How are things shaping up? I haven't cared to risk the wires since Bigsby leaked on us."

Gridley put a foot on the hub of the buckboard wheel and began to whittle a match with a penknife that was as keen as a razor.

"The new chum is in the saddle; look over your shoulder to the left and you'll see him sitting on a cross-tie beside McCloskey," he said.

"I've seen him before. He was over the road last week, and I happened to be in Goodloe's office at Little Butte when he got off to look around," was the curt rejoinder. "But that doesn't help any. What do you know?"

"He is a gentleman," said Gridley slowly.

"Oh, the devil! what do I care about——"
