They descended at length, and Mr Burne sighed with satisfaction; but Yussuf had more wonders of the past to show the travellers, pointing out a narrow path that ran diagonally up the side of the gully, and assuring the party that if they only made up their minds to ascend bravely there was no danger.

Again it was suggested that Mr Burne should sit down and wait; but the only effect of this was to make him obstinate; and he started forward and followed Yussuf up the steep path.

It was decidedly dangerous in places where the stones had crumbled away, and a slip must have resulted in a terrible fall; but all got well over the perilous parts, and at last they climbed to a platform on the side of the huge rocky mass, where the low crumbling walls showed where a kind of temple had once stood. Here they had an opportunity of gazing down into a valley that was one mass of glorious verdure, through which dashed a torrent, whose waters flashed and glittered where the sunbeams pierced the overhanging trees, and made the scene one of the most beautiful they had seen.

There were more wonders yet, for the face of the rock was honey-combed with caverns which ran in a great distance, forming passages and chambers connected one with the other.

These had evidently been inhabited, for there were marks of tools showing how they had been enlarged, and curious well-like arrangements which suggested tanks; but Yussuf assured the travellers that these holes in the natural rock were used as stores for grain, this being the manner in which it was stored or buried to the present day.

“There,” cried Mr Burne, as they came out of the last cave, and stood once more upon the platform of rock by the ruins, and had a glorious panorama of the defile below—“there, I’ve been as patient as can be with you, but now it’s my turn. What I say is, that we must go back to camp at once, and have a rest and a good lunch.”

“Agreed,” said Mr Preston. “You have been patient. What is it, Yussuf?” he cried suddenly, as he saw the guide gazing intently down at something about half a mile away, far along the winding defile.

“Travellers,” said Yussuf; and in that wild, almost uninhabited region, the appearance of fellow-creatures excited curiosity.

They were only seen for a few minutes before the party of mounted and unmounted men with their baggage were seen to curve round a bold mass of rock, and disappear into a narrow valley that turned off almost at right angles to that by which they had come.

The descent proved more difficult than the ascent, and Mr Burne made several attempts to plunge down or slide amongst the débris instead of trusting to his feet; but these accidents were foreseen, and checked by Yussuf, who went in front, and at the first sound of a slip threw himself down and clung to the rock, making himself a check or drag upon the old lawyer’s progress.
