For a few moments neither party addressed the other. Meanwhile the doctor said hurriedly in English:

“What do you think, Haviland? Is it worth while risking all the expedition, and throwing away the fruits of these two years—and all their gain to science, mind—for the sake of a few miserable niggers? If we send them back, they’ll only make slaves of them, and indeed that’s all they’re fit for.”

“Let’s see.” And, turning to the chief, he resumed: “If we send back those who have sought refuge with us, will the chief solemnly promise that they shall not be harmed—that beyond the labour required of them they shall not be killed, or tortured, or ill-treated?”

A low growling chuckle escaped the Arab’s deep chest, and his eyes flashed in haughty contempt.

La Illah il Allah!” he blazed forth. “I will promise this much. They shall groan beneath heavy loads, and shall eat stick in plenty. But first, six of them shall hang by the heels till they are dead, with their eyes scooped out, and a live coal inserted in each socket. Further I promise—that this last shall be the fate of every one in your camp who shall fall into our hands alive, if you hesitate further to send back my slaves. On the holy Kaba I swear it. Now, make your choice. Will you return them, or will you not?”

Haviland looked at Ahern, who nodded his head.

“That settles it,” he said in a cold, decisive tone, turning again to the slaver chief. “Big words, big threats do not frighten us. We send not back to you these people who have sought our protection, to be put to your devilish tortures.”

For a moment, the two parties stood staring at each other in silence. Then Mushâd and his followers withdrew, feeing the others for a little distance, after which they turned, and stalked back to their awaiting forces, the green banner with its sinister symbol seeming to wave defiance and menace as it receded.
