“Of course,” replied Harry. “No wonder that, with an army to back him, he made so many converts. It was, ‘Which will you have, the Koran or the sword?’ And it is so now with this man, only it is worse. Brutal violence of the most horrible description wherever he and his followers go, and there is more stress laid upon the sword than upon the Koran.”

“And the spear added,” said Frank.

“I want the day of escape for us to have come, Hal,” said the doctor, reaching over to lay his hand upon his old school-fellow’s arm. “Our work is done when we have got you away. Let’s leave the punishment of the dervishes to— Ah, here’s Landon back. Well, have they any news for us?”
