"I will be brave," she answered, "May Allah save us!"

They turned their backs upon the ruined temple and hurried along the passage, Mahmoud in advance. When they had traversed about three hundred yards, gradually ascending all the while, the passage ended, and they emerged at a point where three roads met. The center one led down hill to the ruined city, for, now that they had left the tunnel, the light from the volcano was sufficient for them to discern it. It was useless, therefore, taking this; the choice lay between the other two, to the right and the left respectively; which were they to follow? Halima gave her decision.

"We'll try the right," she said; "it saved us once, it may again. We will follow our luck."

There seemed some sense in what she said, so St. Just resolved to act upon it. Additionally, so far as he could mentally take bearings, the direction indicated was that in which lay the camp.

"Agreed," he said; "we can but try the other, should this fail to bring us out. Mahmoud, to the right; go on in front, and keep a good look out."

But now that they had left the tunnel, they found the traveling much harder, for the road was rough and strewn with obstacles—great blocks of stone they had to skirt, and smaller ones embedded in the lava, with which the whole way was covered, so that hardly a step could be taken on the level, and they constantly stumbled, and sometimes found themselves full length upon the ground. Occasionally, their path was completely barricaded by a pile of debris, over which they had to scramble as best they could. Spite of all her husband's care, Halima received several serious bruises, her feet especially smarting and aching, so that she could scarce refrain from moaning; for all that, she made no sound, but struggled bravely on.

They were really traversing the upper portion of the ruined city, for they found themselves passing through the courtyards of deserted houses and by the ends of still standing inner walls, on which St. Just noticed, with a curious sense of half awakened interest, wonderfully executed frescoes of battle scenes, and others. In different circumstances he would have stayed his steps to admire and wonder, for in some cases the pictures were in no way marred, and the colors so fresh that they might have been laid on the day before. But their peril was too great to leave room for admiration of passing objects; so they hurried stumbling on.

Suddenly they found their progress barred; a huge wall of rock loomed high before them; the road went no further; unless there should be a way round this new obstacle, they would have to retrace their steps and try the other road. Seating Halima on a fallen stone—she was now too tired to object to being left while the others searched about—St. Just made his way in one direction along the face of rock, and sent Mahmoud in the other, to see whether a passage could be found.

Presently the boy cried out, "Way here, Master." And almost immediately, St. Just was at his side. An opening had been cut within the rock, and thence, leading downwards was a flight of steps; but the treads were so slippery and uneven from their lava coating, that to descend them would be perilous, though, St. Just thought, possible with care. Should they slip, they might slide down into an almost fathomless abyss. For all that, he resolved to try it; indeed there seemed to be no alternative.

And now something else both puzzled and alarmed him; the air was perceptibly warmer than when they had left the temple, and every moment it grew hotter; he feared the volcano's energy was increasing. Had they escaped entombment in the temple, only to be burnt to death? The thought was maddening; he said nothing of it to his companion, and together they rejoined Halima. He told her of their discovery, and they lost no time in beginning their descent. It was performed in this wise. St. Just seated himself on the top step and then gradually worked himself, with his hands and feet, on to the next; Halima followed behind him in the same position, and Mahmoud came last, propelling himself in like fashion. Thus, in case Halima should slip, her motion would be checked by her husband's body.
