In starting away from the gully, Bill rode at a walk, and with extreme care, Jess going in front, and Finn, not as yet so clever in tracking, following up the rear, and taking very careful observations, not alone of the trail, but also of fallen timber and likely places for snakes. They progressed in this way, in a curving line, for between two and three miles, when Jess came to a momentary halt, and gave one loud bark. Next instant they were all travelling at the gallop for a thick clump of scrub which stood alone in a comparatively clear patch. On the edge of this scrub Finn had a momentary glimpse of their quarry, a big red old-man kangaroo, sitting on his haunches, and delicately eating leaves.
The kangaroo covered over twenty feet of ground in his first leap, and that with a suddenness which must have strained the tendons of his wonderful hind-quarters pretty severely. But, by the time the hunters had reached the scrub, the quarry was between two and three hundred yards distant, travelling at a great rate in fairly open country. Bill had urged his horse to the top of its gallop, and Finn was close behind them. He could have passed them, but was not as yet sufficiently familiar with the man to do so. He felt safer with Bill in full view; and, in any case, the roan mare was a very fast traveller and kept as close to Jess's flying feet as was safe. The old-man seemed confident of his power to outrun his pursuers, for he made no attempt at dodging, taking a straight-ahead course over ground which left him clearly visible almost all the time. That his confidence in his superior speed was misplaced became quite evident at the end of the first mile, for by that time there was not much more than a hundred yards between Jess and himself, in spite of the enormous bounds he took, which made his progress resemble flying. He could take a fallen log in his jump easily enough, but whenever the course rose at all sharply the old-man lost ground; his jumps appearing to fall very short then.
At the end of the third mile Jess, who was galloping in greyhound style, was within twenty feet of the kangaroo; Bill and the roan mare were twelve or fifteen feet behind her, and Finn, running a little wide of the trail, was abreast of the mare's flanks with a fierce, killing light in his eyes. In that order they entered a steep gully which, if the old-man had been on thoroughly familiar ground, he would have avoided. But, as to that, if he had been on familiar ground, he would not have been alone, but the leader of a mob, for which position his commanding size fitted him. Be this as it may, the red old-man plunged straight down the steep gully, and then, fearing to attempt the comparatively slow process of mounting the other side, turned at a tangent and bounded along the bottom of the gully. With a gasping bark, as of triumph, Jess wheeled after him, and the roan mare, unable to turn quite so swiftly, left Finn to shoot ahead for the first time, perhaps fifteen paces behind Jess.
