He mounted quickly, urged the reluctant mare to the break in the edge of the cliff, and forced her over. For some thirty feet the trail went down the face of the precipice, much like a fire escape on the wall of a tenement house, barely wide enough to accommodate horse and rider,––so narrow, indeed, that Haig’s left leg 243 was scraped and bruised by hard contact with the stone. At the bottom of this incline, his amazement was great at finding a solid platform of rock, on which, he was able easily to turn and go down another incline underneath the first. Plainly all this was not the result of accident; the hands of men had been busy here; and picks and shovels had supplemented the work of nature. But below the next platform there certainly had been a secondary slide of rock, for the trail was nowhere discernible, though it should evidently have slipped down, at a greater angle from the cliff than before, to a third turning point on a shelf some forty feet away to the left. Here the débris was loose and fine, and with a little urging Trixy was induced to take the descent, carrying quantities of sand and stones with her as she slid and sprawled safely to the next goal.
Thus they went, sometimes finding the trail plain over solid rock and hard-packed débris, sometimes slipping and scrambling among stones and sand, but always drawing nearer and nearer in a zigzag course, now easy and then difficult, to the green vale below. There were moments when Trixy was on her knees, moments when she was on her haunches, moments when she stood swaying above the pit, and moments when all traces of the trail had vanished. But somewhere below was Sunnysides.
Far down the declivity, so near the valley that Haig was able to look across into the tops of the tallest pines, they came to what appeared to be the last of the rocky ledges. Having for some minutes seen nothing of the outlaw, Haig supposed that the runaway had already reached the meadow, and was by now on the trail 244 through the forest. But just as Trixy’s shod hoofs struck the platform with a clatter, Haig caught sight of Sunnysides far out on the narrow shelf. He was trotting briskly along, for the shelf was smooth and level. But, on a sudden he stopped, stood a moment with his head thrust forward and down, and then turned cautiously around, his four feet bunched together on the narrow footing.
“What’s up now?” ejaculated Haig.
And then he saw it. Twice before he had noted where a similar error might have been made, on other ledges farther up; and he himself had avoided them only by carefully studying the aspect of the declivity below him. Sunnysides had undoubtedly lost time through such mistakes; and now he was trapped. At the point where he stood, the shelf ended abruptly “in the air”; and between him and the exit at the other end of the platform was Haig. The trail had come down to about the middle of this platform, which was like an unrailed balcony, scarce three feet in width, with a high wall of rock on one side, and on the other a straight drop of twenty feet to a veritable chute of stones that terminated in a widespread litter of débris on the meadow.
“Caught like a rat!” cried Haig. “I’ve got you now!”
But what could he do with him? His rope was useless on that meager footing, where there was barely room for his horse to stand, much less for Haig to swing a noose. And worse: if Sunnysides was trapped, so was his enemy; for the horse was already, through fright or belligerency, moving slowly toward Haig. In 245 a flash it was clear to Haig that the outlaw meant to have it out with him then and there; and that there would be no time to turn Trixy, and find the outlet into the valley.
“It’s too bad, but––”
He drew his revolver, and waited. There was yet a chance, he thought, or hoped, that the horse would halt, and postpone the issue. He did not want to kill him; he had not come across Thunder Mountain to kill him; he had come to take him back to Paradise Park. And so he waited––fatally. The outlaw came slowly until half the space between him and Haig had been covered. Then, at a distance of perhaps a hundred feet, when no choice was left to him, Haig swung up his gun, and fired. At that very instant, Sunnysides uttered a savage cry, a shrill neigh ending in a scream; and, charged at the horse and rider in his path.
Haig fired again, and missed; threw himself forward on Trixy’s neck, jerked the pony’s head in toward the wall, and fired again; and missed. He tried to shoot once more, into the very face of the oncoming brute, but too late. There was a vision of flaming black eyes and white teeth, in a yellow blur; and then a tremendous impact, a crash. Trixy was flung back on her haunches, with one hind leg over the edge of the shelf, Haig barely hanging in the saddle. The outlaw leaped back, and lunged again; thrust himself between Trixy and the wall; toppled pony and rider off into the void; and passed on, with a shriek of triumphant rage.
