“Here is the trail of the chief, Señor; he came from yonder and went in that direction.”

“Are you sure, Arima?” demanded Harry. “I can see no sign of the passage of a man through this grass.”

“Very possibly not, Señor,” answered Arima dryly, “because, you see, you are not accustomed to tracking; moreover, this trail is some days old, and was made while the grass was wet and beaten down by the rain. But it is there, nevertheless, for practised eyes to read, and, being found, can now be easily followed. When the chief passed here he was in a terribly exhausted state, and staggered as he ran, exactly as Mama Cachama described, for just here he stumbled—if your honour will take the trouble to dismount you can see the mark where the toe of his boot dug into the soil—and I think the spot where he fell finally cannot be very far from here.”

“In that case,” said Harry, “let us press on as quickly as possible, for even minutes may be of inestimable value now. As to dismounting and examining the marks for myself, we have no time for that at present, Arima, and I am quite content to take your word for it that matters are as you say. Can you follow the trail mounted, or must you proceed on foot?”

“I can follow it mounted, Señor, seeing that I was mounted when I found it,” answered Arima. “But it will be well that you should ride a few yards behind me, lest the trail should swerve suddenly to right or left and be crossed by your mule.” So saying, the Indian sprang into his saddle and, turning the head of his animal, rode forward at a foot pace, his eyes intently searching the sea of waving grass before him. For a quarter of an hour he rode on thus, with Harry, leading Butler’s horse, following a yard or two in his rear; then he suddenly reined his mule aside and, pointing to a barely perceptible depression in the grass, said:

“See, Señor, there is where the chief first fell, as described by Mama Cachama—yes—and,”—as his keen eyes roved hither and thither—“yonder is the spot where he fell and lay.”

A few paces brought them to the spot indicated, and here the signs were clear enough for even Escombe’s untrained eyes to read, the grass being still depressed sufficiently to show that a human form had lain there motionless and stretched at length for several hours; moreover, at that part of the depression where the man’s head had rested, the grass blades were still flecked here and there with dried, ruddy froth, beneath which lay a little patch of coagulated blood, from which a swarm of flies arose as Arima bent over it and pointed it out to Harry. But the fugitive had disappeared, and the Indian gave it as his opinion that the chief had revived after lying insensible for about six hours, and had immediately resumed his interrupted flight. As to the direction in which he had gone, there was no difficulty in determining that, for, leading away toward the eastward there were two wavering lines, close together, traced through the long grass by the feet of the wanderer, and still distinct enough to be followed by even so inexperienced a tracker as the young Englishman.

“Now, Arima,” exclaimed Harry, “is there anything worth knowing to be gained by a prolonged examination of this ‘form’? Because, if not, we will press on at once, since time is precious. The chief went in that direction, of course—even I can see that—and the trail is so clear that we ought to be able to follow it at a canter.”

“Yes, quite easily, Señor,” acquiesced Arima. “There is nothing to be learned here beyond the fact that the Señor Butler fell at this spot, and lay absolutely motionless for so long a time that he must have been in a swoon. Then he revived, sat up, rose to his knees—see, there are the impressions of his two knees, and of the toes of his boots behind them—then he stood for several minutes, as though uncertain whither he would go, and finally struck off to the eastward. But see how the trail wavers this way and that way, even in the short length of it that we can trace from here. He moved quite aimlessly, not knowing whither he would go; and I think that, if he is still alive when we find him, Señor, he will be quite crazy.”

“So much the greater reason for finding him as quickly as possible. Mount and ride, Arima,” exclaimed Harry, pressing his heels into his mule’s sides, and urging the animal into a canter along the plainly marked trail until he was taught better by the Indian.
