The fire had been eating slowly through a stretch of manzanita chaparral, whose hard stems resisted them as the evergreens could not. Though the wind still blew up-canyon, they approached the river gorge at right angles, and were able to make their way to the lower levels in the shelter of the East side of a dry creek bed, where the hot blast could not reach them.
They were stooping to drink at a spring when the terrified neigh of a horse sounded from a clump of saplings almost behind them. In the same instant the stretch of seedling firs that clothed the creek bank, showering into sparks at the far end, shot toward them sky rockets of leaping flame. Turning in a panic to race out at right angles from this unexpected peril, they thought to make time on horse-back. The animal was tied and hobbled with a rawhide lariat!
Frantically the hobbled horse jerked at the rawhide.
Pedro plucked Ted by the arm and tried to drag him on, for the fire was snapping through the under-brush at the speed of an express train. Its sound was that of many trains, and its wind hot as the breath of a blast furnace.
But as Ted had stooped to cut the thongs, his parched nostrils had caught a cooler breath. It seemed to issue from a cranny in the rocks behind the clump of saplings. Then it was too late: The shooting tongues of red were upon them. Dragging Pedro down beside him,—for the roar drowned his voice,—he waited, reasoning that the two- or three-foot seedlings would go like tinder, leaving a strip of ground hot, to be sure, but no longer flaming.
If they could but endure its passing! He turned to press his scorched face against the rock wall.
To his amazement, he fell into a cave mouth, tripping Pedro, who stumbled after him. Quick as thought they dragged the horse in after them and held him, trembling and snorting, his eyes rolling wildly, during that blistering moment until the line of fire had passed them.
“We’re safer now than before,” declared Ted. “This made a fine back-fire, didn’t it?—Let’s rest awhile.” His nerves were taking toll of him. “Ground’s too hot yet anyway.”
For perhaps an hour they rested, flat on the floor of the cave,—after having tied the horse to a bowlder just outside. He was a fine animal, black as jet and as high-spirited as Spitfire himself. Ted appraised him with longing eyes, for he loved horses as Ace loved his ship. But who could he belong to, and how did he come to be there?
His bridle was embellished with silver. “Mexican handiwork, that!” Pedro thought. But the mystery was no nearer solution.
