"I don't like shooting a horse," Cumshaw remarked. "It's like murder."

Bradby's only answer was a muttered oath. The trials of the Journey were bringing out the worst side of the man, a side that Cumshaw had never seen before. He eyed his companion thoughtfully. If the wilderness was to get on Bradby's nerves at this early stage, Cumshaw could see that there was likely to be very serious trouble before the end came. The air in the highlands was laden with a freshness which, while it stung the men to action, at the same time put a keen edge on their tempers. Both of them were children of the warm, sun-kissed lowlands, and the difference of even a few degrees of temperature had a remarkable effect on them. With Abel Cumshaw it was such as to send a warm glow into his cheeks; the cold bite of the air made his blood sparkle like new wine and urged him on to fresh efforts. It affected Mr. Bradby in another and a worse way. He became sullen, and there was a certain marked vindictiveness in the way he spurred his lame horse on to exertions that were plainly too much for it. Once or twice Abel was on the point of remonstrating with him, but for the sake of peace he held his tongue and waited, in the hope that the day would bring forth some measure of relief. But nothing happened that morning, and the hope died within him.

Late that day, when the pace had slowed down almost to a crawl, they stumbled across the place by the simplest kind of accident. They had been dropping down to lower levels the greater part of the day, and somewhere about three o'clock in the afternoon—they were not quite sure of the hour, since the sun was masked by the trees—they found themselves in what looked like a narrow gully. Both sides of it were lined with thick bushes of golden wattle that shut out all view on either hand. There were shadows galore in this narrow gully, and the place itself looked almost as dark as the entrance to the Pit. Cumshaw, who had a classical education and had not been able to forget it, any more than the fact that he had once been a gentleman, murmured under his breath.

"What's that?" Bradby asked sharply.

Cumshaw repeated his quotation. "Facilis est descensus Averno," he said.

"What does that mean?" Bradby enquired, in the tone of a man who imagines he is being insulted in a language he does not understand.

"It's easy to go to hell," Cumshaw translated.

Bradby shot one sharp curious glance at him, but made no comment on what he had said. They rode on in silence.

Presently they came to a patch of ground that had been broken by the wind or the rain, or perhaps both together. The shadows so fell that the travellers did not realise the treacherous nature of the soil until they were right in the middle of it. Cumshaw's horse floundered and would have fallen on its knees had he not reined in sharply. This caused him to cannon into his companion's mount. Bradby pulled back sharply, in some way jarring his animal's sore leg as he did so. It reared up on its haunches with the pain, and in the most approved manner bucked its rider off. He shot up in the air, described a beautiful half-circle, and sailed through the barrier of wattle like a human projectile.

Cumshaw slipped off his horse with the quickness of thought. He had enough presence of mind to tether both his own and Bradby's mount, and then he cautiously parted the bushes. For the moment he could see nothing but a great wall of golden blossoms, and then out of the depths came Bradby's furious voice. He was cursing the horse and the slope and everything and everyone within hearing in the simple and forceful fashion of the Australian bushman.
