The stones used in building the pyramids of Egypt, it is supposed, were raised to their places by piling up immense inclined planes of sand, up which the blocks were pushed with rollers. If inclined planes were used to raise large blocks to a great height, is it to be supposed that a similar mode, or _railroads_, were not used to convey them on a level plane? The statement, often repeated on high authority, that the pyramids were built before the Egyptians acquired the art of writing hieroglyphics, however, which they do contain, do not convey that full knowledge of the state of the arts among them, at the time the pyramids were constructed, which is to be learned from the writings and pictures in their tombs and temples, in regard to the state of their arts at a subsequent period. But we have the less valuable authority of Herodotus that the blocks of stones were lifted from one course to the other up the steps of the pyramid. Remains of Cheops’ grand causeway, for transporting the blocks quarried from the rocks on the east bank, are still seen leading up the great pyramid from the plain, a shapeless ridge of ruinous masonry and sand. According to Herodotus, it was one thousand yards long, sixty feet wide, and forty-eight feet high, was adorned with figures of animals, and was a work of ten years. Some of the stone used for the coping over the passages are seven feet thick and more than seventeen feet long. Lifting these stones up the side of a pyramid four hundred and fifty feet high was certainly a work of great labor; but as a feat of engineering it was mere child’s play compared with some of the triumphs of modern science and skill,—for instance, lifting the Menai bridge on to its piers, or raising on end and placing on its pedestal the monstrous monolith which adorns the city of St. Petersburg. _RAILROADS FROM 1760—ENGLAND._
