Immersed in reverie, she had trusted the conduct of her horse almost entirely to his own discretion. A hackney exceptionally good in the slow paces, as are many Australian horses, the Wanderer had, for his own pleasure and satisfaction, gone forward at the top of his walking speed, which was sufficiently fast to keep her companion's horse at a jog-trot. From time to time, at an earlier stage, the rustic maiden had laughingly protested; then Wanderer was held back. However, in this particular instance the failure of consideration was unnoticed, until Estelle was aroused by a cry from her companion, so loud and vehement in tone that she knew at once that no ordinary occurrence had called it forth. Reining up sharply, she turned in her saddle to behold a sight which blanched her cheek and well-nigh froze the life-blood in her veins. From out the tangled forest growth, emerging from behind a gigantic eucalypt, two men, masked and armed, had stepped into the roadway, abreast of the gold-buyer and the trooper. A third man, half hidden by the bushes, levelled his fire-arm a few paces in the rear. Both girls sat horror-stricken on their horses as the trooper's carbine and the fire-arms of the robbers appeared to make simultaneous reports. The gold-buyer fell heavily from his horse in the road; the trooper staggered and swayed in the saddle, dropping his reins, but recovered himself, though evidently hard hit and unable to control his horse. The wounded man rose to his knees, but at that moment one of the masked strangers rushed over and struck him over the head. Estelle's eyes darkened, and she felt as if all sensation was leaving her; but, recovering herself, she shook her reins, and the free horse dashed down the slope leading to the creek of which they had been told, with the speed of a racer, accompanied by her terror-stricken companion, whose hackney followed suit with the instinct of his kind. The creek was crossed almost immediately. Mile after mile fled away like a dream before either of the girls thought of drawing rein. At length, at the foot of a steep and rocky range, the horses commenced to slacken speed. 'My God!' said the girl, 'did you see that? They have murdered my poor uncle! Whatever shall we do? Do you think they will come after us? Is there any house that we can go to along this horrid road? I know we shall both be killed and planted so as never to be heard of again.' 'Let us think over our best course,' said Estelle, aroused to the necessity of self-possession in the hour of need, and in the presence of a weaker nature. 'I remember this range. Five miles on the other side is an inn, near a water-race. If we can get there we are safe; there seemed to be a good many people about when we passed up. But I hear horses galloping after us. Good heavens!' They stopped, and, listening, could plainly hear the sound of more than one horse coming fast along the rocky road behind them.
