Big, fat Mustapha, jolting up and down on his own donkey, would lead the way, and showed them each day some of the many strange and curious things to be seen in and around the city, until finally George felt quite as much at home in Cairo as did his new found friends.

One day they hurried through lunch to go to see the "Whirling Dervishes," a queer lot of people, who spin around and around like a top, as fast as ever they can, until they are so tired they drop on the floor. They saw the "Howling Dervishes," too, men in gowns of many colours, with wild faces and long hair, whose blood-curdling howls as they swayed themselves to and fro almost frightened George, who could not understand how people could possibly do such queer things as an act of worship. These are only two of the many sects of the Mohammedan religion.

One day they crossed over to the island in the river Nile, where Mustapha knocked at a gate which was opened by a man in a long green gown, and they found themselves in a garden among trees loaded with oranges and lemons. Here George crept behind the boys along the top of a wall to a spot where, so the story runs, the baby Moses was found asleep in his cradle in the bulrushes by a daughter of the Pharaoh. The Pharaohs were the ancient kings of Egypt. It was most interesting for George, who was surprised indeed to find this land of Mohammedanism had recollections also of his own Christian religion.

Another day they all rode out to a place named Heliopolis, where long ago there was a great city called the City of the Sun. Now only a tall granite obelisk stands there, and any little American can see its "twin," as George called it, if he or she will go to New York City and look at the big obelisk which stands in Central Park. Once upon a time several obelisks stood side by side at Heliopolis, but the Khedive, the ruler of Egypt, some years ago wanted to make a valuable present to the United States, so he gave them one of these obelisks, the same which to-day may be seen in New York City.

When they visited the great Museum Uncle Ben and George stood amazed before the great mummy cases and the petrified mummies themselves (many of them the old kings of Egypt), which have been buried for thousands of years, and only recently been brought to light. It is by preserving all these great finds, dug up from the soil often in the most unexpected places, that it has been possible to write the history of Egypt.


CHAPTER III
THE BOYS CLIMB THE PYRAMIDS

"Uncle Ben, I am going to ride the Pasha out to the Pyramids," announced George, as they were talking over their plans for a trip to the great Pyramids of Gizeh. They had just come in from a ride, and Nabul and Abdal were anxiously waiting, fearful lest the tall Effendi would say, "Well, boys, we won't need you to-morrow."
