And this huge pile was built over forty centuries ago. It seems a long time, but when you figure out how many lives it means it is not so old after all. Every one of us knows one hundred men who have reached forty years. Their aggregate lives, if patched together, would go back to the beginning of this monument. In other words, if a man at forty should have a child and that child should live to be forty and then have a child, and the programme of life should so continue, it would take only one hundred such generations to reach to the days when the breath from the garlic and onions eaten by those one hundred thousand men polluted this desert air. Indeed, the world is not old, and it is not hard to realize that those people of the past had the same troubles, the same worries, and the same tastes as we have. I can take you through tombs not far from Cairo upon the walls of which are portrayed the life work of the men of ancient Egypt. You may see them using the same farm tools that the _fellaheen_ use now. They plough, they reap, and thresh. They drink wine and gorge themselves with food. In one of the tombs I saw the picture of a woman milking a cow while her daughter held the calf back by the knees to prevent it from sucking. In another painting I saw the method of cooking, and in another observed those old Egyptians stuffing live geese with food to enlarge their livers. They were making _pâté de foie gras_, just as the Germans stuff geese for the same purpose to-day. Leaving the Pyramid of Cheops, I crossed over to take a look at the other two which form the rest of the great trio of Gizeh, and I have since been up to the site of old Memphis, where are the Pyramids of Sakkarah, eleven in number. Along this plateau, running up the Nile, are to be found the remains of a large number of Pyramids. There are also some in the Faiyum, and others far up the river in ancient Ethiopia. The latter are taller in proportion to their bases than the Egyptian Pyramids, and they generally have a hall with sculptures facing the east to commemorate the dead. Most of the stones of the Pyramids here came from the plateau upon which they stand or from the Mokattam hills about twelve miles away on the other side of the Nile. There was an inclined plane leading to the river, on which are still to be seen the ruts in the stone road cut out by the runners of the sledges carrying these great blocks. There are pictures on some of the monuments which show how the stones were drawn on sledges by oxen and men. In one of the pictures a man is pouring oil on the roadbed. On the Island of Madeira, where the natives drag sleds by hand up and down the hills, they grease their sled runners, but the ancient Egyptians greased not only the runners but the roads as well.
