And as he went he patted the side-pocket of his coat, where his old-style revolver still reposed; he remembered the way Krausz had whipped out his weapon the evening before, and the thought was hardly reassuring.

He found the doctor as he had left him, and under the direction of the Germans the natives were beginning to make the dirt fly. Krausz looked up, his heavy eyes narrowing slightly at sight of the American's face; then he smiled cordially.
