After this youth, several others took part in the debate. Then they all stood up, and, to the surprise of their visitors, began to sing—very sweetly—an old familiar hymn!

“It minds me o’ home,” whispered Hockins, scarce able to restrain the tears that filled his eyes.

The hymn was nearly finished, when a rushing sound and a subdued cry were heard to issue from a dark passage, the mouth of which was close to the couch of our travellers. The singing ceased instantly. Next moment a man rushed into the chamber with labouring breath and flashing eyes. Springing towards Ravonino, he spoke several words eagerly, at the same time pointing in the direction of the passage just referred to.

“Lights out and silence!” cried the guide, authoritatively, in the native tongue.

Another moment and the cave was in total darkness, and a silence so profound reigned there that the three visitors could hardly persuade themselves the whole affair was not a strange dream. The voice of Ravonino, however, soon dispelled that idea.

“Be still!” whispered the guide, laying his hand on Mark’s shoulder. “Our foes have discovered our retreat.”

“There’s a lot of stout fellows here,” returned Mark, also in a whisper. “We will help you if you have to fight.”

“We may not fight,” replied Ravonino softly. “If it be God’s will, we must die. Hush! They come.”

Once more total silence prevailed in the cavern, and the sound of distant voices could be heard. In a few minutes a tiny light was seen at the end of the dark passage. It gradually increased in size, revealing a soldier who bore a torch. He advanced on tip-toe, and with slightly scared looks, into an outer cavern which formed a sort of vestibule to the large inner cave.

The soldier was brave, no doubt, and would have faced an army in the field, but he was extremely superstitious, and advanced with a palpitating heart, the torch held high above his head, and eyes glancing nervously from side to side. A crowd of comrades, similarly affected more or less, followed the torch-bearer and pushed him on.
