"I know a few words." "Where did you learn them?" "In Khartum." Thereafter he was left alone with Durrance on the glacis, and the two men talked together for the best part of an hour. At the end of that time the Arab was seen to descend the glacis, cross the trench, and proceed toward the hills. Durrance gave the order for the resumption of the march. The water-tanks were filled, the men replenished their zamshyehs, knowing that of all thirsts in this world the afternoon thirst is the very worst, saddled their camels, and mounted to the usual groaning and snarling. The detachment moved northwestward from Sinkat, at an acute angle to its morning's march. It skirted the hills opposite to the pass from which it had descended in the morning. The bushes grew sparse. It came into a black country of stones scantily relieved by yellow tasselled mimosas. Durrance called Mather to his side. "That Arab had a strange story to tell me.
