“But mightn’t that have been one of the apes reared up for the time?”

“Oh no, sir,” said the sentry. “I shouldn’t mistake a monkey for a man; and besides, they don’t wear boots.”

“Ah! and do you say these people who came near you wore boots?”

“Well, it sounded like it, sir, for when I fired I could hear the leather squeak.”

“Humph!” grunted Captain Roby; and Dickenson, who was full now of his adventure in what seemed to have been near the same place, spoke out:

“I think there’s something in what he says:” and he related his own experience. “At the time, I was so occupied in getting back for something to eat that I forgot all about the matter after dinner. But now this has occurred I begin to feel that the chirping sounds I heard really were signals, and that I did hear voices talking together afterwards.”

“Then it must have been Kaffirs sneaking there for water after it was dark.”

“But the footsteps?” said Lennox.

“Well, Kaffirs have feet.”
