The movements of the workers became automatic. The teams had to be removed because the horses had become unmanageable under the torture of the heat. When any one spoke it was in a hoarse whisper because of a swollen larynx. Mechanically they dug, shoveled, grubbed, handkerchiefs over their faces to protect from the furnace glow.

A deer with two fawns emerged from the smoke and flew past on the way to safety. Mice, snakes, rabbits, birds, and other desert denizens appeared in mad flight. They paid no attention whatever to their natural foe, man. The terror of the red monster at their heels wholly obsessed them.

The fire-break was from fifteen to twenty feet wide. The men retreated back of it, driven by the heat, and fought with wet sacks to hold the enemy. A flash of lightning was hurled against Dave. It was a red-hot limb of a pine, tossed out of the gorge by the stiff wind. He flung it from him and tore the burning shirt from his chest. An agony of pain shot through his shoulder, seared for half a foot by the blazing branch.

He had no time to attend to the burn then. The fire had leaped the check-trail at a dozen points. With his men he tried to smother the flames in the grass by using saddle blankets and gunnysacks, as well as by shoveling sand upon it. Sometimes they cut down the smouldering brush and flung it back across the break into the inferno on the other side. Blinded and strangling from the smoke, the fire-fighters would make short rushes into the clearer air, swallow a breath or two of it, and plunge once more into the line to do battle with the foe.

For hours the desperate battle went on. Dave lost count of time. One after another of his men retreated to rest. After a time they drifted back to help make the defense good against the plunging fire devil. Sanders alone refused to retire. His parched eyebrows were half gone. His clothes hung about him in shredded rags. He was so exhausted that he could hardly wield a flail. His legs dragged and his arms hung heavy. But he would not give up even for an hour. Through the confused, shifting darkness of the night he led his band, silhouetted on the ridge like gnomes of the nether world, to attack after attack on the tireless, creeping, plunging flames that leaped the trench in a hundred desperate assaults, that howled and hissed and roared like ravenous beasts of prey.

Before the light of day broke he knew that he had won. His men had made good the check-trail that held back the fire in the terrain between Bear and Cattle Cañons. The fire, worn out and beaten, fell back for lack of fuel upon which to feed.

Reinforcements came from town. Dave left the trail in charge of a deputy and staggered down with his men to the camp that had been improvised below. He sat down with them and swallowed coffee and ate sandwiches. Steve Russell dressed his burn with salve and bandages sent out by Joyce.

"Me for the hay, Dave," the cowpuncher said when he had finished. He stretched himself in a long, tired, luxurious yawn. "I've rid out a blizzard and I've gathered cattle after a stampede till I 'most thought I'd drop outa the saddle. But I give it to this here li'l' fire. It's sure enough a stemwinder. I'm beat. So long, pardner."

Russell went off to roll himself up in his blanket.

Dave envied him, but he could not do the same. His responsibilities were not ended yet. He found his horse in the remuda, saddled, and rode over to the entrance to Cattle Cañon.
