In proportion as the trees become taller and as they stand closer together, the ground below is freer from shrubbery, and may be scanned from a certain distance with greater ease. Nevertheless the soil is more rocky, ledges crop out on the surface, isolated blocks appear, boulders, and sometimes low, dyke-like protuberances.
When Topanashka felt certain of the proximity of the trail, he scanned the ground very carefully. It was still flat, notwithstanding some rocky patches. The shade was deep, and as far as the eye reached, nothing moved; nothing suspicious was seen, nay, nothing that bore life, except the sombre vegetation. The wind increased in force; the pines faintly murmured from time to time; a blast penetrated beneath them to the surface of the soil, chasing the dry needles in fitful whirls or playing with the tall bunch-grasses that were growing profusely here.
If any man was about he certainly kept outside the range of vision. So the old man reasoned, and he began to creep toward a place where the smoothness of the rocks indicated the wear and tear of human feet. It was the only trace of the trail, and barely visible. As he approached the place he knew that he must be seen, but he relied upon the fact that a man lying flat on the ground is very difficult to hit. An arrow could scarcely strike him, and in no case could the wound be other than slight, for the shot must come from a distance, as there was, he felt certain, no one near by.
He glided like a snake, or rather like a huge lizard, which crawls over obstacles, and whose body adapts itself to depressions instead of crossing or bridging them over. His cautious progress scarcely caused a leaf to rustle or a stone to rattle, and these noises were perceptible only in the vicinity of where they were produced. So he pushed himself gradually close up to a ledge, which, while of indifferent height, still protected his body somewhat. On this ledge he expected to notice scratches which indicated that the trail passed over it.
It was as he suspected,—the rock was slightly worn by human feet; but of fresh tracks there could of course be no trace here, for only long and constant wear and tear, and not an occasional hurried tread, can leave marks behind. But Topanashka noticed a few fragments of rock and little bits of stone that lay alongside the old worn-out channel. Without lifting his head, he extended his arm, grasped some of the fragments, and began to examine them.
Loose rocks or stones that have been lying on the ground undisturbed for some time, always have their lower surface moist, while the upper dries rapidly. When the yellowish tufa of these regions becomes wet, it changes colour and grows of a darker hue. Topanashka had noticed that some among the stones which he was examining were darker than the others. The Indian, when he examines anything, looks at it very carefully. One of the fragments was darker on the surface; of this he felt sure, as when he removed them he was careful to keep them as they lay. Below, the piece had its natural colour, that of dry stone. He assured himself that the darker shade really proceeded from humidity; it was still moist. The fragment, therefore, must have been turned over; and that, too, a very short time ago. Only a large animal or a man could have done this. He looked closely to see whether there were any scratches indicative of the passage of deer-hoofs or bear-claws, but there were none except those that appeared so large as to show plainly from a distance. There was every likelihood, therefore, that some human being had but very lately moved the stones, and not only since the rain of last night but since the surface had had time to dry again; that is, in the course of the afternoon.
He moved his body forward where he could examine the soil alongside the ledge. The grass was nowhere bent and broken, still that was no sufficient indication. There at last was a plain human track, the impression of a naked foot with its toe-marks to the north, and the impression was fresh! But the Tehua walked on round sandals. Had he not lost one of them? It was very uncomfortable walking on one of the circular disks only. Topanashka rose on hands and feet and crept farther, regardless of what might be behind him. His eyes were directed northward and he relied upon his ear to warn him of danger in the rear.
The trail lay before him quite distinct for a short distance. Close to it some grasses were bent, and on the sandy place near by there was a print as if from a small hoop, but the impression was old and partly blurred. In vain did the old warrior search for other marks; the rain had obliterated everything except this faint trace that might originally have been plainer because deeper. It looked as if the wearer of the sandal had stepped on the grass-bunch with the fore part of his foot, slipped back lightly, and thus pressed the hind part of the hoop deeper into the soil. In that case some trace of the heel-print might still be found. And indeed a very slight concavity appeared behind the impression of the sandal. The heel was turned from the north, consequently the man was going to, not coming from the Rito. The tracks were surely old ones.
Everything was plain now. The Tehua had lost one of his sandals and was returning on his bare feet. But why should he leave it? Why did he not take it along? Even that Topanashka could easily explain. People from the Rito frequently roamed over the northern mesa, close to the Tyuonyi. He might have noticed the presence of some of them, and have fled in haste, leaving his foot-gear behind. Most likely the ties or thongs had given way, and he had no time to mend them. That was an evidence also that the man was alone, else he would not have fled with such precipitation. Neither was he in this vicinity any longer. Topanashka felt that his task was done; he could not gain anything by proceeding farther.
"Kuawk, kuawk, kuawk!" sounded overhead. A crow had been sitting quietly on the tree above him, but now it flew off again, the unlucky bird! Its cry startled the old man, and he raised his head to look after the herald of evil, following him with his eye. All was still. Then he rose to his knees.
