One sight was pointed out which made us shudder. This was the dark stain of Sultan Hassan's blood on the pavement. He was murdered in the mosque by his Mamelukes. His tomb is just in the middle of the inner inclosure. On it we saw a copy of the Mohammedan holy book, the Koran. It was splendidly illuminated in gold and colours. The sultan's tomb was once covered with a rich embroidered covering, but this was faded and moth-eaten when we saw it. The marble pavement, too, was broken in many places. The mosque of Sultan Hassan has always been famed for its beauty. It is said that the sultan cut off the head of the architect, that he might never build another as beautiful. From the mosque of Sultan Hassan we went to the mosque of Sultan Tuloon. It was built about the year 879 after the birth of our Lord, and is said to be the oldest mosque in Cairo. It has double rows of handsome pointed arches. There is a fine view from the chief minaret. Our guide told us that it even excels that from the citadel. But the staircase is spiral, is outside, and in rather a ruinous state. [Illustration: MOSQUE.] On reaching the second gallery, some of us became faint-hearted and stayed to rest. Even from it the view was a grand one; but those who went to the top said that we had really seen nothing in comparison. Lucy was tired and giddy when we came down, so some of us went home with her while the rest went to see the mosque of El Ghoree. "It is beautifully painted," said Hugh, when giving us an account of it afterwards. "And inside there are pillars of marble and mother-of-pearl." "Those are in the niche for prayer," his father said. "The windows and walls of the mosque, and the roof, are ornamented with stone carved like lace-work. But I think, Hugh, that what I admire most are the horseshoe arches, and the four grand columns which look as if they had belonged to some ancient temple." "What did the man call that niche for prayer?" Hugh asked. "The Mahrab. In every mosque the Mahrab looks in the direction of Mecca, where Mohammed was born; and which is therefore to the Mohammedans the most sacred of cities." "Do they pray towards Mecca, then, just as Daniel prayed towards Jerusalem?" "Yes, they do. When we were looking at the Mahrab, I, like you now, thought of Daniel, and wished for the day when the knowledge of the gospel shall have spread over the earth, and when all places for prayer shall be used for the service of the only true God, and Jesus Christ whom he has sent." "I should like to make one little Egyptian girl a Christian," said Lucy; "would not you, Hugh?" "But how could we, Lucy?" "Oh! we could talk to her, and teach her our hymns, and tell her about our Bible pictures." "Only," Hugh answered, thoughtfully, "she would not understand what we said, and we should not understand her." "I forgot that. Mamma, may we learn Egyptian?"
