We went to the upper chamber over the west tower of the old gateway, and there saw the record described by Sir Gardner Wilkinson. The upper part with the Greek inscription; below it a symbol of the Deity, a globe supported by two winged angels; and on each side six figures, which Sir Gardner Wilkinson believes to be the twelve apostles. We were very much interested in this Christian record, and wished that we had had some knowledge of who these early Christians were who had left the traces of their assembly in this upper chamber. [Illustration: OLD GATEWAY.] We next went to see the mosque of Amer. This mosque was built by the Saracen Amer on the spot on which he encamped with his army when he besieged the city and took it. He founded the city of Fostat, which became the capital of Mohammedan Egypt. Four hundred years afterwards the present city of Cairo was built by one of the caliphs. He made it the capital, and called it Masr-el-Kahira, or "the Victorious City." The city built by Amer was then called "Old Cairo." We were not so much struck by the mosque of Amer as we had been by some other mosques. There are some fine pillars and arches, both pointed and circular. But its chief interest is its great age. There is an old tradition that whenever this mosque falls, the Mohammedan power will fall in Egypt. From Old Cairo we crossed over to the Island of Roda, to see the Nilometer. It consists of a square well, in the middle of which is a pillar marked in degrees, for measuring the rise of the Nile. There was once a tower over it. At the time when the Nile is rising, the criers come into Cairo every morning to proclaim the height to which it has risen since the previous morning. This overflow of the Nile irrigates the country for a long distance from its banks, and makes them very fruitful. From the Nilometer we went to see the gardens belonging to Ibrahim Pacha; then to the spot where Moses is said to have been found by Pharaoh's daughter. We could picture the cradle of bulrushes floating on the still waters; the royal princess coming down with maidens to bathe, the anxious Miriam watching with eager eyes to see what would be the fate of her baby-brother. Hugh and Lucy both said that it made the Bible seem much more real to them, now that they were in the very land where so many of God's wonders of old were wrought. We all felt it so, as we looked at the spot where Moses was preserved in his babyhood, while floating in his cradle in the very waters which afterwards at his word, by God's command, were turned into blood. Our next expedition was to the tombs of the Mameluke kings. We rode through a not very interesting part of Cairo to the "Bab-el-Nasr," or "Gate of Victory."
