“’Stinguished itself,” growled Bob.

But the darkness was only apparent for a few moments, for about fifty yards ahead there was a bright gleam of sunshine at the mouth of the cavern, and two shadows moved, which proved to be Mak and the pigmy peering in as if listening and trying to make out what was going on inside.

“Hi, you sir!” shouted Dean. “We have caught your spirit. Come and help him out.”

But as if grasping the lad’s meaning by the tone of his voice, Mak turned sharply and darted away at a rate which carried him in a series of bounds down the slope of the great kopje, so that by the time the little party of explorers were out in the broad sunshine with their captive, Mak was threading his way amongst the rocks, closely followed once more by the pigmy, and about to disappear.

“There, gents!” cried Buck. “What do you make of him, sir?” And he thrust his captive more into the light. “Why, he must have been a monkey as big as me when he was in full fettle.”

“Monkey!” cried Mark. “Why, it’s a man!”

“Man, sir!” cried Buck scornfully. “He arn’t a black; he’s grey. Who ever see a man like that?”

“Not I,” said the doctor, laughing.

“There, Mr Mark,” cried Buck triumphantly.

“But a man it is, Buck,” said the doctor. “Poor old fellow! Doesn’t say much for the natives’ civilisation, for there must have been some living near. Crawled into that cave to die. Now, I should say he’s one of their old priests or medicine men, who, taking advantage of his great age and supposed wisdom, has imposed upon his fellows till he got to be looked upon as one who held intercourse with the unknown world, and lived upon his reputation, till his fellows grew to look upon him and talked about him as a spirit. That’s why Mak objected to our exploring this cave. Poor fellow, he meant well; and he made his objections no doubt in our interest, for fear that we might come to harm.”
