them disappear across the sands with some sinking of heart. All next day I was too well occupied to give them much thought, but when six o’clock came and ’Alî set watchers upon the castle walls, I began to feel anxious. Half-an-hour later Ma’ashî, the sheikh’s brother and my particular friend, came running down to my tent. “Praise God! my lady Khân, they are here.” The Arabs gathered round to offer their congratulations, and Fattûḥ rode in, grey with fatigue and dust, with the caravan at his heels. He had reached Kerbelâ at five in the morning, found the muleteers, bought provisions, loaded the animals, and set off again about ten. “And the oranges are good in Kerbelâ,” he ended triumphantly. “I have brought your Excellency a whole bag of them.” It was a fine performance. The Arabs who inhabited Kheiḍir had come there two years before from Jôf in Nejd: “Because we were vexed with the government of Ibn er Rashîd,” explained ’Alî, and I readily understood that his could not be a soothing rule. The wooden howdahs in which the women had travelled blocked one of the long corridors, and some twenty families lodged upon the ground in the vaulted chambers of princes. They lived and starved and died in this most splendid memorial of their own civilization, and even in decay Kheiḍir offered a shelter more than sufficient for their needs to the race at whose command it had been reared. Their presence was an essential part of its proud decline. The sheikh and his brothers passed like ghosts along the passages, they trailed their white robes down the stairways that led to the high chambers where they lived with their women, and at night they gathered round the hearth in the great hall where their forefathers had beguiled the hours with tale and song in the same rolling tongue of Nejd. Then they would pile up the desert scrub till the embers glowed under the coffee-pots, while Ma’ashî handed round the delicious bitter draught which was the one luxury left to them. The thorns crackled, a couple of oil wicks placed in holes above the columns, which had been contrived for them by the men-at-arms of old, sent a feeble ray into the darkness, and Ghânim took the rebâbah and drew from its single string a wailing melody to which he chanted the stories of his race. “My lady Khân, this is the song of ’Abdu’l ’Azîz ibn er Rashîd.” He sang of a prince great and powerful, patron of poets, leader of raids, and recently overwhelmed and slain in battle; but old or new, the songs were all pages out of the same chronicle, the undated chronicle of the nomad. The thin melancholy music rose up into the blackness of the vault; across the opening at the end of the hall, where the wall had fallen in part away, was spread the deep still night and the unchanging beauty of the stars. “My lady Khân,” said Ghânim, “I will sing you the song of Ukheiḍir.” But I said, “Listen to the verse of Ukheiḍir”--
