He went to Memphis. Memphis was a great and powerful city, situated in what was called Lower Egypt, on the Nile, just above where the branches which form the mouths of the Nile separate from the main stream. All that part of Egypt is flat country, having been formed by the deposits brought down by the Nile. Such land is called _alluvial_; it is always level, and, as it consists of successive deposits from the turbid waters of the river, made in the successive inundations, it forms always a very rich soil, deep and inexhaustible, and is, of course, extremely fertile. Egypt has been celebrated for its unexampled fertility from the earliest times. It waves with fields of corn and grain, and is adorned with groves of the most luxuriant growth and richest verdure.
