There was comfort once more in the fresh thought which came, suggested by his experience in the skirmishes in which he had been engaged, and by his duties in tending the wounded.

For he recalled how, in the majority of cases, unless some important vessel was divided, Nature interposed as the great surgeon for the preservation of her children’s lives, causing the veins to chill and contract, and the bleeding to cease; and as Scarlett Markham knelt beside his father, and pressed his lips to the icy brow, he prayed that it might be so now, and that his life might be spared.

“Now, what is to be done?” he said to himself, half rising, as if the act he had done had given him refreshment and a new access of thought.

He stood for a few moments thinking, and then, feeling his way about the place, he satisfied himself where the openings out of the little vault lay, his doubt as to which led to the lake being solved by the steps down to where it was formerly water, but which on testing he now found to be firm floor, and by the little heap of rusty arms over which he nearly fell as he crept about.

His first need was light and help for his father, and to obtain these he felt that perhaps it would be best to surrender.

With this aim in view, he made his way back along the passage, kicking against and recovering his sword, and up the flight of narrow stone steps, becoming conscious that the air was growing warmer as he proceeded, and finally that the walls were hot, while straight before him, as he reached the top and tried to penetrate into the chamber, there was a confused pile of heavy stones leaning towards him, as if some party wall or portion of the roof had fallen in that direction, and blocked the way.

He could not stay to investigate, the heat was too great; but the freedom with which he breathed taught him that the ruins had not completely stopped all the chamber, for a steady current of air was flowing past him from below.

He felt instinctively that the fire must have done its work, and that the greater part of the secret passage had been obliterated by the falling ruins, so that he must not look for help from that direction.

Retracing his steps, then, he once more reached the vault, whose coolness was pleasant after the stifling heat above. Then, crossing the dark place, he slowly descended the steps, and went onward with extended hands, feeling his way toward the two entries—the original, and that which had been broken through by the fallen tree.

He had not far to go before a faint light stole down to guide his way, and he reached the spot where the passage was roofed in with dead branches and twigs, and as he reached it, just faintly heard, came the shrill cry of a blackbird—Pink-pink-pink!—from somewhere in the wood above.
