"No, they can't do that. I must go. Perhaps if I screamed at them they would take me for an evil spirit and run away."

"But what then?" said Mary. "You could not go round and release the poor man; you would be seen."

"Yes; it was a foolish idea. But something may suggest itself. Oh, I can't bear to think about the poor man."

"If you go, I go too," said Tommy. "I won't leave you."

The two set off, and felt their way stumblingly through the passage. Presently they were aware of a pungent aromatic smell, that increased as they went on. This was explained when they reached the opening in the wall; looking over stealthily, they saw, sixteen or twenty feet below them, on the floor of the cave, a strange bewildering sight. A ring of dusky men held aloft great flaring torches which gave out a heavy smoke that penetrated into the tunnel. Without the circle there stood a row of drummers beating a rhythmic music on their instruments; within, a crowd of men were leaping in wild gyrations, uttering frenzied yells. In the haze nothing could be seen distinctly; all was a confused whirl. The prisoner was quite invisible.

The dance continued for a long time, the movements becoming ever more violent and fantastic, the cries more frantic, the drumming more swift and vigorous. At last, when the din was at its highest, the drummers gave one tremendous crash and dropped their sticks. The whirling and the yells ceased as by magic; the performers flung themselves fainting on the ground; and there was a great silence. But only for a few minutes. Then the men leapt to their feet again, rushed to the side of the cave, and returned, bringing the food laid there in readiness, and many gourds filled with the fermented sap of palm-trees. The torch-bearers stuck their torches in crannies on the walls, and the whole company gave themselves up to feasting. The girls turned sick as they watched the ravening gluttony of the men, and withdrew their eyes.

"Let us go back," whispered Tommy.

"No, no, wait," said Elizabeth; "I want to know what will happen."

Crouching below the opening, they waited for what seemed hours. The barbarous noise continued, voices were raised in excitement; but presently the uproar diminished, and finally ceased. Glancing down again, they saw the natives lying in all sorts of attitudes. Exhausted by the orgy, drunken with wine, they had fallen into a heavy sleep.

Some of the torches had gone out. Though the illumination was dimmer, the smoke was so much less that objects could more easily be distinguished. Against the wall at the right hand the girls saw what appeared at first to be a large bundle. But in a few moments they recognized the form of a man—an old man with a long white beard.
