As a pebble striking an anthill stirs into angry life a thousand startled workers, so a mountain washout startles a division and concentrates upon a single point the very last reserve of its activities and energies.

For thirty minutes the wires sung with Callahan's messages. When his special for a run to the Rat Cañon was ready all the extra yardmen and both roadmasters were in the caboose; behind them fumed a second section with orders to pick up along the way every section man as they followed. It was hard on eight o'clock when Callahan stepped aboard. They double-headed for the pass, and not till they pulled up with their pony truck facing the water at the mouth of the big cañon did they ease their pace.

In the darkness they could only grope. Smith Young, roadmaster of the Pilot branch, an old mountain boy, had gone down from Sleepy Cat before dark, and crawling over the rocks in the dusk had worked his way along the cañon walls to the scene of the disaster.

Just below where Dry Dollar Creek breaks into the Rat the cañon is choked on one side by a granite wall two hundred feet high. On the other, a sheer spur of Sleepy Cat Mountain is thrust out like a paw against the river. It was there that the wall of water out of Dry Dollar had struck the track and scoured it to the bedrock. Ties, steel, ballast, riprap, roadbed, were gone, and where the heavy construction had run below the paw of Sleepy Cat the river was churning in a channel ten feet deep.

The best news Young had was that Agnew, the division engineer who happened to be at Sleepy Cat, had made the inspection with him and had already returned to order in men and material for daybreak.

Leaving the roadmasters to care for their incoming forces, Callahan, with Smith Young's men for guides, took the footpath on the south side to the head of the cañon, where, above the break, an engine was waiting to run him to Sleepy Cat. When he reached the station Agnew was up at the material yard, and Callahan sat down in his shirt sleeves to take reports on train movements. The despatchers were annulling, holding the freights and distributing passenger trains at eating stations. But an hour's work at the head-breaking problem left the division, Callahan thought, in worse shape than when the planning began, and he got up from the keg in a mental whirl when Duffy at Medicine Bend sent a body blow in a long message supplementary to his first report.

"Bear Dance reports the fruit extras making a very fast run. First train of eighteen cars has just pulled in: there are seven more of these fruit extras following close, should arrive at Sleepy Cat at four A.M."

Callahan turned from the message with his hand in his hair. Of all bad luck this was the worst. The California fruit trains, not due for twenty-four hours, coming in a day ahead of time with the Mountain Division tied up by the worst washout it had ever seen. In a heat he walked out of the operators' office to find Agnew; the two men met near the water tank.

"Hello, Agnew. This puts us against it, doesn't it? How soon can you give us a track?" asked Callahan, feverishly.

Agnew was the only man on the division that was always calm. He was thorough, practical, and after he had cut his mountain teeth in the Peace River disaster, a hardheaded man at his work.
