"Medina is about two hundred and fifty miles north of Mecca," said the Doctor, "and is only a third the size of the latter city. It is next to Mecca in sanctity, and a great many pilgrims go there every year. The tomb of the Prophet is in a large mosque, in the centre of the city, and there is an old story that the coffin of Mohammed is suspended in the air by invisible threads hanging from heaven. Captain Burton visited Medina, and reports that the Moslems have no knowledge of the story, and say it must have been invented by a Christian. The tomb is in one side of the building, but no one is allowed to look upon it, not even a Moslem; the most that can be seen is the curtain surrounding it, and even that must be observed through an aperture in a wooden screen. The custodians say that any person who looks on the tomb of the Prophet would be instantly blinded by a flood of holy light." [Illustration: VIEW OF MEDINA (FROM A DRAWING BY A NATIVE ARTIST).] So much for the two holiest places in the eyes of the Moslems. Frank and Fred concluded that they did not care to go to Mecca and Medina, and the former instanced the old fable of a fox who despised the grapes which were inaccessible, and denounced them as too sour to be eaten. As they entered the Gulf of Suez the attention of the boys was directed to Mount Sinai, and they readily understood, from the barrenness and desolation of the scene, why it was called "Mount Sinai in the Wilderness." With a powerful telescope not a sign of vegetation was anywhere visible. It was late in the forenoon of a pleasant day when the ship came to anchor, as we have described in our opening lines. The Quarantine doctor came on board, and was soon convinced that no reason existed why the passengers, who chose to do so, might not go on shore. Doctor Bronson and his young friends bargained with a boatman to carry them and their baggage to the steps of the Hotel de Suez for a rupee each. The town, with the hotel, was about two miles from the anchorage, and the breeze carried them swiftly over the intervening stretch of water. Half a dozen steamers lay at the anchorage, waiting for their turn to pass the Canal; and a dozen or more native craft, in addition to the foreign ships, made the harbor of Suez appear quite picturesque. The rocky hills behind the town, and the low slopes of the opposite shore, glistened in the bright sunlight; but the almost total absence of verdure in the landscape rendered the picture the reverse of beautiful. Not a tree nor a blade of grass can be seen on the African side of the Gulf, while on the opposite shore the verdure-seeking eye is only caught by the oasis at the Wells of Moses, where a few palm-trees bid defiance to the shifting sands of the desert.
