"_Allah il allah!_" said Yar Ali piously. "Those dogs have beaten me until it is as though every bone in my body were broken. Dismount, I beg thee, _sahib_, and let me probe for that accursed bullet, and dress thy shoulder to the best of my meager ability." While this was going on, Yar Ali spoke, avoiding his friend's eye, "You said, _sahib_, you said something about--about seeing? What saw ye, in Allah's name?"
