“Oh, the words of a man in a scare go for nothing,” said Captain Roby contemptuously.

“Perhaps not; but this fellow was in no scare when he called for his companion—Dirck, did he call him, Lennox?”

“Yes, Dirck; and he must be somewhere close at hand. Look, Bob.”

He touched his comrade’s arm to draw his attention to the sneering smile on the prisoner’s face.

“And where do you think his friend is?” said Captain Edwards.

“In the same place as this man came from. They have a hiding-place somewhere close by.”

“Yes,” cried Dickenson; “one that enables them to play a regular Jack-in-the-box trick.”

“But how? Where?” said Captain Edwards.

“I don’t know how, and I don’t know where it is,” replied Lennox; “but I do know that they have a hiding-place somewhere here amongst the rocks. This Boer was not here one minute; then we heard the creaking and grinding of a stone door close at hand, and he was standing out against the sky.”

“Whereabouts?” said Captain Roby.
