The five men detailed at the trap mouth, were grouped thereat, just behind a cluster of silver wattles, ready for any emergency. It seemed to them that their services would not be required.

But, see! the warrigal!

There is no time to reason. In a flash they streak out from cover and ride straight at the flying barb. Something must happen. The fearful impact, narrowly escaped but an hour ago, occurs. There is no attempt on either side to avoid the issue. With a mighty bound and a savage snap of his teeth the warrigal flings himself at the foremost, bringing horse and rider down with a crash, both lying motionless upon the plain.

At the same moment, and scarce a length behind, came Yellow Billy. His attempt to head the runaway was blocked by the impact of the steeds. Too near to swerve, his horse struck the leading beast on the hind-quarters at the moment of the crash, adding to the confusion, and coming down a cropper.

Staggered by the violent collision, the stallion is brought to a sudden stop, but not to the ground. And now an astounding thing happens. Yellow Billy, while falling with his steed, to save himself from the warrigal's feet clutched frantically at that animal's mane, and, by a clever vault, to the amazement of his comrades, sprang upon the outlaw's back.

It would be hard to say if at that particular moment the horse himself was cognisant of the act. The pause covered but the fraction of a second. With a bound he leaped the fallen bodies, and, there being no one in front to stay him, tore off in a direction that skirted the trap fence.

CHAPTER XXII

HOW YELLOW BILLY BROKE THE WARRIGAL

"The snorting of his horses is heard from Dan: at the sound of the neighing of his strong ones the whole land trembleth."—JEREMIAH.

The tragic ending of the last rush held all breaths for some brief moments. Such a contretemps had never happened before. It beat all previous experiences. The vanishing horse and rider seemed a wild fantasy of the brain, that passes like the breaking of a soap-bubble. There, before their very eyes, lay the slain; the victims of the mad charge.
