They both plunged upwards again, now quite abreast, vying with each other to reach the summit as if with the one thought only. Already the sting and smart of acrid fumes were in their eyes and nostrils; when they at last stood on level ground again, it was hidden by a thin film of grayish blue haze that seemed to be creeping along it. But above was the clear sky, seen through the interlacing boughs, and to their surprise—they who had just come from the breathless, stagnant hillside—a fierce wind was blowing! But the roaring was louder than before.
“Unless your three men are already here, your game is up,” said the major calmly. “The wind blows dead along the ridge where they should come, and they can't get through the smoke and fire.”
It was indeed true! In the scarce twenty minutes that had elapsed since the sheriff's return the dry and brittle underbrush for half a mile on either side had been converted into a sheet of flame, which at times rose to a furnace blast through the tall chimney-like conductors of tree shafts, from whose shriveled sides bark was crackling, and lighted dead limbs falling in all directions. The whole valley, the gully, the Bar, the very hillside they had just left, were blotted out by a creeping, stifling smoke-fog that scarcely rose breast high, but was beaten down or cut off cleanly by the violent wind that swept the higher level of the forest. At times this gale became a sirocco in temperature, concentrating its heat in withering blasts which they could not face, or focusing its intensity upon some mass of foliage that seemed to shrink at its touch and open a scathed and quivering aisle to its approach. The enormous skeleton of a dead and rotten redwood, not a hundred yards to their right, broke suddenly like a gigantic firework into sparks and flame.
The sheriff had grasped the full meaning of their situation. In spite of his first error—the very carelessness of familiarity—his knowledge of woodcraft was greater than his companion's, and he saw their danger. “Come,” he said quickly, “we must make for an opening or we shall be caught.”
The major smiled in misapprehension.
“Who could catch us here?”
The sheriff pointed to the blazing tree.
“THAT,” he said. “In five minutes IT will have a posse that will wipe us both out.”
He caught the major by the arm and rushed him into the smoke, apparently in the direction of the greatest mass of flame. The heat was suffocating, but it struck the major that the more they approached the actual scene of conflagration the heat and smoke became less, until he saw that the fire was retreating before them and the following wind. In a few moments their haven of safety—the expanse already burnt over—came in sight. Here and there, seen dimly through the drifting smoke, the scattered embers that still strewed the forest floor glowed in weird nebulous spots like will-o'-the-wisps. For an instant the major hesitated; the sheriff cast a significant glance behind them.
“Go on; it's our only chance,” he said imperatively.
