As soon as Mr. M'Intyre had selected the horses that were to be saved and used, he left the other work to the Captain, and, accompanied by Jacky, started off on the tracks of the outlaw. Before long they met some of the pursuers returning. Their horses were knocked up, and they had failed to trace the runaway. "Deeficult as the country may be," mused Mr. M'Intyre, "Jacky's equal to onything in the trackin' line. It's only a maitter o' time when we'll run 'em doon."

There was much speculation at the camp over the fate of the half-caste. It did not lean to pessimism, though jeremiads were uttered by some. The pals, who knew Billy's ability better than the others, had unlimited faith in their mate. Whatever happened to the steed, the boy would turn up safe and sound. The steer rider, in their opinion, could ride bare-back the toughest outlaw that ever sniffed the wind. "You'll see," said Tom confidently to the Captain, "Billy'll more'n hold his own."

"Didn't youse tell us the other day thet at your gra-at billy-horse-ma-ale-robbery, the steer slung the yallar bhoy——"

"Oh!" retorted Tom pettishly, "that was only——"

Just then the returning men rode up. They had no good news to relate, but said that by Mr. M'Intyre's orders all were to proceed to the Glen, and if the missing boy was not brought in before dark they were to disperse. Let us now follow the fortunes, or misfortunes, of Billy.

As soon as he found himself astride the warrigal, the yellow boy held fast with knees and hands, the stock whip over his shoulder trailing in a long line behind the flying pair. To stick on the racing horse was a comparatively easy thing to Billy, unless, indeed, some fiendish trick should unseat him. But to guide the scurrying brute, unbitted, unreined, were as impossible as to turn and check a Mont Blanc avalanche.

The first instinct of the horse upon escaping from the trap-yard was to dismount his rider by violent means, but there are eager pursuers on the track—so away!

He rounds the trap fence, bolts down the grassy valley apace, twists up a gully with a swerve that almosts unseats Billy, dashes into Glen Creek, and mounts the bank to enter a defile. The first shock over, the half-caste begins to realise his position. For a moment a pang of fear seizes him, and some of the dread possibilities of the ride dawn upon him. This soon yields to a different sensation as they rush through space.

There is that in the half-wild nature of the lad which goes out in unconscious sympathy for the bestridden beast. Despite the mutual antagonism, which, after all, is not that of hate, there is in some way a sense of kinship. Wild answers to wild. Man nature comes thus into close gripping quarters with horse nature. There is no intervening saddle. Flesh mates with flesh, and spirit answers to spirit. Whose, then, shall be the victory? The strains of many generations of desert lords is in the quadruped. But what of the biped? A curious admixture of blood there! On the white side are the well salted strains, which hark away back to the old Vikings. On the other and darker, the stream points backwards to the misty past, when his ancestors, subtle and slim, moved southward from the older civilisations of the north, and swarmed the valleys of the Ganges and the Indus, fighting for a foothold.

Is not this a challenge to the latent forces in the wild blood of the human? It riots through the youth's veins, giving vim and sparkle to his courage. Who shall win the lordship? Away then, and away!—through the mountain pines till clothes are mere shreds, and breast and thighs are torn and blooded with innumerable scores; slithering down the gorges to the accompaniment of rattling stones; jumping fallen timber, and smashing through the undergrowth, till all pursuit has faded away—the infuriated steed holds his course. On, on! ever up to the inaccessible heights.
