"See 'em run, General? Going in, I hear."

"Boys, I'd like to have you meet Mr. Mowbray," said the explorer, introducing the two. "You aren't going to British territory, I suppose?"

"Never you mind, my son," snapped the little man. "Give me back my map. Just got in from Washington an hour ago, and leave in another hour. I'll need that map worse than you will—got wind of something big."

As Schoverling pulled out the folded map and handed it over, Mowbray lowered his voice.

"I'll beat you there by some time, old boy, but I'll be around. Let you in on it, if I can't handle it. Good-looking boys, there. Keep your ears open for a nigger who says 'Me debbil man.' You can trust him. Got to go, General. Mighty glad to have met you, boys—see you later, maybe. Besselama!"

"Jumping sandhills!" ejaculated Charlie. "Who's he? A grand mogul around here? What's that last word mean?"

"Arabic for 'so-long,'" smiled the General.

"What made 'em all shut up when he handed it to them?" inquired Jack curiously.

"That's the chap, of course, who lent me the map, boys." And the General spoke very seriously. "You must never repeat what he said to a soul, or mention his name. In British Africa they have hunted him for years, by regiments; there's a price on his head of some thousands of pounds, and he's slipped into and out of the country whenever he liked. He's defeated the Somali troops and even the white regulars time and again, and no one knows how he gets into the ivory country. He does it for sheer love of the game, for he has a fortune of his own."

"You mean," asked the puzzled and wondering Charlie, "that he's one of the ivory raiders?"
