However, step by step Jim had tracked them; sometimes losing the trail altogether, sometimes guided merely by a fresh-made scratch on the surface of a stone, or by a broken twig or bruised blade of grass. At last, he traced it far out into the bush, many miles beyond the furthest range of settlements, and then he lost it altogether. There had been a halt, for some time, at this spot.
Beyond this, Jim was entirely at fault. He made circle after circle round the spot, but could find no trace whatever of their passage, and returned to the point where he had missed the trail. He relit the embers of the fire which the bush rangers had made, cooked some food, and laid himself down—first to think it over, then to sleep, for it was now just the close of day.
It was clear to him that here, more than anywhere else, the bush rangers had made a great effort to throw anyone who might be pursuing them off the trail. He had no doubt that the bush rangers had muffled their horses' hoofs with cloth, and had proceeded with the greatest care through the bush, so as to avoid breaking a single twig in their passage; and the only reason for such greater caution could be that it was here, and here only, that they wished to throw the pursuers off the trail. It would have seemed, to a white man, that they had done this before, especially when they had kept in the water course; but to black Jim's perception, it appeared that they had been more careless than would be expected; and that, while apparently doing their utmost to conceal their tracks, they had really left sufficient indications to allow a practised tracker to follow them.
Why then, now that they were far beyond the settlements, and fairly in the country of their native allies, should they, for the first time, so hide their trail that he could not discover it?
The result of Jim's thoughts was that, when he awoke at daybreak, he started back towards the settlements. When he came to the river which the party had passed, in pursuit of the natives, he kept along its bank, scrutinizing the ground with the greatest care. After six miles' walking he suddenly stopped, at a point where the soft turf near the margin was cut up by the passage of the party of horsemen. Here was the confirmation of his ideas.
Arguing the matter out with himself, Jim had arrived at the conclusion that, hitherto, the trail had been a false one, the bush rangers' object being to lead their pursuers to believe that they had gone far out into the native country; whereas, in fact, their hiding place was somewhere among the settlements. Should this be so, the only way to find them was to search for their back track. This he had now found and, with a shout of triumph at his own cleverness, Jim forded the river and followed the track of the horses.
This was now clear enough, the horsemen taking no pains whatever to conceal their traces, feeling perfectly confident that any pursuers must now be thrown off the scent. Jim followed it till sundown, when he had made some thirty miles; and then, withdrawing some little distance from the tracks, he made his fire and camped for the night.
He was now inside the line of the outlying stations, and had approached to the edge of a bit of wild and broken country, which offered so few inducements to settlers that it had been passed by for the better land beyond; although occasionally, when herbage was scarce, the settlers in the neighbourhood drove the animals up to feed among its hills. The black had no doubt that the gang, of which he was in pursuit, had their haunt somewhere in the heart of this wild and little-known tract.
In the morning he again started and, after travelling several miles, entered a narrow valley with very steep sides, with trees and brushwood growing wherever they could get a foothold. He now adopted a careless and indifferent carriage and, although he kept a sharp lookout, no one who saw him would have supposed that he had any particular object in view.
Presently he noticed that the tracks turned sharply off from the line he had followed, in the centre of the valley; and entered the trees, which grew thickly here at the foot of the hills. He made no halt, even for an instant, but walked straight on. Half a mile further he sat down and lit his fire, and began to cook some food. He had no doubt that he was watched for, just after he passed the point where the track turned off, he heard a very low whistle among the trees.
