And the animal herself, untamed, unchecked, frothing at her bit, her sides a-lather with foam, her barrel tuckered like that of a finely trained race-horse, rushed blindly on. The forest echoed and reëchoed with the dull thud of her hoofs as they pounded the thick underlay of rotting cones. And her rider breathed hard as he lay with his head beside the reeking neck, and watched for the coming of the end.
Suddenly, in the midst of the gray, he saw a flash of sunlight. It was like a beacon light to a storm-driven mariner. It was only a gleam of sunshine and was gone almost at once, but it told him that he was fast coming on the river. The final shoals, maybe, where wreck alone awaited him. Just for an instant his purpose wavered. There was still time to drop to the ground. He would have to chance the mare’s flying heels. And it might save him.
But the idea was driven from his head almost before he realized it; the mare swerved like a skidding vehicle. He clung desperately to her mane, one arm was even round her neck in a forcible embrace. The struggle lasted only a few seconds. Then, as he recovered his equilibrium, he saw that she had turned into what was undoubtedly a well-defined, but long-disused, forest trail. The way was clear of obstruction. The trees had parted, opening up a wide avenue, and above him shone the perfect azure of the summer sky.
He was amazed. Where could such a trail lead? His answer came immediately. Away ahead of him, towering above the abundant foliage, he saw the distant shimmer of snowy peaks, and nearer—so near as to make him marvel aloud—the forest-clad, broken lands of the foot-hills. Immediate danger was past and he had time to think. At all cost he must endeavor to stop the racing beast under him. So he began a vicious sawing at her mouth. His efforts only drove her faster, and caused her to throw her head higher and higher, until her crown was within six inches of his face.
The futility of his purpose was almost ludicrous. He desisted. And the Lady Jezebel lowered her head with an angry snort and rushed on harder than ever. And now the race continued without relaxing. Once or twice Tresler thought he detected other hoof-marks on the trail, but his impression of them was very uncertain. One thing surely struck him, however: since entering this relic of the old Indian days, a decided change had come over the mare. She was no longer running blind; more, it seemed to him that she displayed that inexpressible familiarity with her surroundings which a true horseman can always detect, yet never describe. This knowledge led him to the hope of the passing of her temper.
But his hope was an optimistic mistake. The sweat pouring from neck, shoulders, and flanks, she still lifted her mud-brown barrel to her mighty stride, with all the vim and lightness of the start. He felt that, jade that she was, she ran because she loved it; ran with a delight that acted as a safety-valve for her villainous temper. She would run herself into amiability and then stop, but not before. And he knew her temper so well that he saw many miles lying ahead of him.
The rift was gradually widening, and the forest on either side thinned. The trees were wider and more scattered, and the broken hilltops, which but now had been well ahead, were frowning right over him, and he knew, by the steady, gradual rise of the country, that he would soon be well within the maze of forest, crag, and ravine, which composed the mountain foot-hills.
At last the forest broke and the ragged land leapt into full view with magical abruptness. It was as though Nature had grown her forest within the confines of a field embraced by an imaginary hedge. There were no outskirts, no dwindling away. It ended in one clean-cut line. And beyond lay the rampart hills, fringed and patched with disheveled bluff, split by rifts and yawning chasms. And ever they rose higher and higher as the distance gained, and, though summer was not yet at its height, it was gaunt-looking, torn, chaotic, a land of desolation.
The mare held straight on. The change of scene had no effect on her; the trail still lay before her, and she seemed satisfied with it. Tresler looked for the river. He knew it was somewhere near by. He gazed away to the right, and his conjecture was proved at once. There it lay, the Mosquito River, narrowed and foaming, a torrent with high, clean-cut banks. He followed its course ahead and saw that the banks lost themselves in the shadow between towering, almost barren hills, which promised the narrow mouth of a valley beyond.
And as he watched these things, a feeling of uneasiness came over him. The split between the hills looked so narrow. He looked for the trail. It seemed to make straight for the opening. As the ground flew under him, he turned once more to the river and followed its course with his eyes, and suddenly he was thrilled with his first real feeling of apprehension. The river on the right, and the hill on the left of him were converging. Nor could he avoid that meeting-point.
