“What would you say to cotton cloth, and thick brass wire, and glass beads, being the chief currency in Central Africa?” said Harold.

“You don’t mean it, sir?”

“Indeed I do, and as these articles must be carried in large quantities, if we mean to travel far into the land, there will be more bales and coils than you and I could well carry in our waistcoat pockets.”

“That’s true, sir,” replied Disco, looking earnestly at a couple of negro slaves who chanced to pass along the neighbouring footpath at that moment, singing carelessly. “Them poor critters don’t seem to be so miserable after all.”

“That is because the nigger is naturally a jolly, light-hearted fellow,” said Harold, “and when his immediate and more pressing troubles are removed he accommodates himself to circumstances, and sings, as you hear. If these fellows were to annoy their masters and get a thrashing, you’d hear them sing in another key. The evils of most things don’t show on the surface. You must get behind the scenes to understand them. You and I have already had one or two peeps behind the scenes.”

“We have indeed, sir,” replied Disco, frowning, and closing his fists involuntarily, as he thought of Yoosoof and the dhow.
