"You're funny," said the man.

"My friends tell me so," admitted Bones. "But there's nothin' funny about drink. Acquainted as you are with the peculiar workin's of the native psychology, dear sir, you will understand the primitive cravin' of the untutored mind for the enemy that we put in our mouths to steal away our silly old brains. I wish you 'bon voyage.'"

"So long," said Mr. Corklan.

Bones went back to the Residency and made his report, and there, for the time being, the matter ended. It was not unusual for wandering scientists, manufacturers, and representatives of shipping companies to arrive armed with letters of introduction or command, and to be dispatched into the interior. The visits, happily, were few and far between. On this occasion Sanders, being uneasy, sent one of his spies to follow the adventurer, with orders to report any extraordinary happening—a necessary step to take, for the N'gombi, and especially the Inner N'gombi, are a secretive people, and news from local sources is hard to come by.

"I shall never be surprised to learn that a war has been going on in the N'gombi for two months without our hearing a word about it."

"If they fight amongst themselves—yes," said Captain Hamilton; "if they fight outsiders, there will be plenty of bleats. Why not send Bones to overlook his sugar experiments," he added.

"Let's talk about something pleasant," said Bones hastily.

It was exactly three months later when he actually made the trip.

"Take the Zaire up to the bend of the Isisi," said Sanders one morning, at breakfast, "and find out what Ali Kano is doing—the lazy beggar should have reported."

"Any news from the N'gombi?" asked Hamilton.
