The surface fire on the hills licked up the brush, mesquite, and young cedars with amazing rapidity. If his trail-break was built in time, Dave meant to back-fire above it. Steve Russell was one of his party. Sanders appointed him lieutenant and went over the ground with him to decide exactly where the clearing should run, after which he galloped back to the mouth of Bear.

"She's running wild on the hills and in Cattle Cañon," Dave told Crawford. "She'll sure jump Cattle and reach San Jacinto. We've got to hold the mouth of Cattle, build a trail between Bear and Cattle, another between Cattle and San Jacinto, cork her up in San Jacinto, and keep her from jumping to the hills beyond."

"Can we back-fire, do you reckon?"

"Not with the wind there is above, unless we have check-trails built first. We need several hundred more men, and we need them right away. I never saw such a fire before."

"Well, get yore trail built. Bob oughtta be out soon. I'll put him over between Cattle and San Jacinto. Three-four men can hold her here now. I'll move my outfit over to the mouth of Cattle."

The cattleman spoke crisply and decisively. He had been fighting fire for six hours without a moment's rest, swallowing smoke-filled air, enduring the blistering heat that poured steadily at them down the gorge. At least two of his men were lying down completely exhausted, but he contemplated another such desperate battle without turning a hair. All his days he had been a good fighter, and it never occurred to him to quit now.

Sanders rode up as close to the west edge of Bear Cañon as he could endure. In two or three places the flames had jumped the wall and were trying to make headway in the scant underbrush of the rocky slope that led to a hogback surmounted by a bare rimrock running to the summit. This natural barrier would block the fire on the west, just as the burnt-over area would protect the north. For the present at least the fire-fighters could confine their efforts to the south and east, where the spread of the blaze would involve the Jackpot. A shift in the wind would change the situation, and if it came in time would probably save the oil property.

Dave put his horse to a lope and rode back to the trench and trail his men were building. He found a shovel and joined them.

From out of Cattle Cañon billows of smoke rolled across the hill and settled into a black blanket above the men. This was acrid from the resinous pitch of the pines. The wind caught the dark pall, drove it low, and held it there till the workers could hardly breathe. The sun was under entire eclipse behind the smoke screen.

The heat of the flames tortured Dave's face and hands, just as the smoke-filled air inflamed his nostrils and throat. Coals of fire pelted him from the river of flame, carried by the strong breeze blowing down. From the cañons on either side of the workers came a steady roar of a world afire. Occasionally, at some slight shift of the wind, the smoke lifted and they could see the moving wall of fire bearing down upon them, wedges of it far ahead of the main line.
