It was a great day in the Muslim year. The Mahmal, or Sacred Carpet, was leaving Cairo on its long pilgrimage of thirty-seven days to Mecca and Mahomet's tomb. Great guns boomed from the Citadel, as the gorgeous procession, forming itself beneath the Mokattam Hills, began its slow march to where, seated in the shade of an ornate pavilion, Prince Kaid awaited its approach to pay devout homage. Thousands looked down at the scene from the ramparts of the Citadel, from the overhanging cliffs, and from the tops of the houses that hung on the ledges of rock rising abruptly from the level ground, to which the last of the famed Mamelukes leaped to their destruction. Now to Prince Kaid's ears there came from hundreds of hoarse throats the cry: "Allah! Allah! May thy journey be with safety to Arafat!" mingling with the harsh music of the fifes and drums. Kaid looked upon the scene with drawn face and lowering brows. His retinue watched him with alarm. A whisper had passed that, two nights before, the Effendina had sent in haste for a famous Italian physician lately come to Cairo, and that since his visit Kaid had been sullen and depressed. It was also the gossip of the bazaars that he had suddenly shown favour to those of the Royal House and to other reactionaries, who had been enemies to the influence of Claridge Pasha. This rumour had been followed by an official proclamation that no Europeans or Christians would be admitted to the ceremony of the Sacred Carpet. Thus it was that Kaid looked out on a vast multitude of Muslims, in which not one European face showed, and from lip to lip there passed the word, "Harrik--Harrik--remember Harrik! Kaid turns from the infidel!" They crowded near the great pavilion--as near as the mounted Nubians would permit--to see Kaid's face; while he, with eyes wandering over the vast assemblage, was lost in dark reflections. For a year he had struggled against a growing conviction that some obscure disease was sapping his strength. He had hid it from every one, until, at last, distress and pain had overcome him. The verdict of the Italian expert was that possible, but by no means certain, cure might come from an operation which must be delayed for a month or more. Suddenly, the world had grown unfamiliar to him; he saw it from afar; but his subconscious self involuntarily registered impressions, and he moved mechanically through the ceremonies and duties of the immediate present. Thrown back upon himself, to fight his own fight, with the instinct of primary life his mind involuntarily drew for refuge to the habits and predispositions of youth; and for two days he had shut himself away from the activities with which David and Nahoum were associated. Being deeply engaged with the details of the expedition to the Soudan, David had not gone to the Palace; and he was unaware of the turn which things had taken.
