Besides this division into districts, the Egyptians had one other, and only one--the division into Lower Egypt, or the North Country (_Tomera_, or _To-meh_), and into Upper Egypt, or the South Country (_To-res_). Lower Egypt consisted of the Delta; Upper Egypt stretched from the southernmost point of the Delta to the first cataract. This division has the advantage of corresponding exactly to the configuration of the country; moreover, it preserves the memory of a period before the time of Menes, during which Egypt was divided into two separate kingdoms--that of the North and that of the South, a division which in later times had often a decisive influence upon the course of events. This state of things was of sufficiently long duration to leave an ineffaceable trace upon the official language of Egypt, and upon that which we may call its blazonry, or heraldic imagery. The sovereigns who united the whole territory under one sceptre are always called, in the royal protocols, the lords of Upper and Lower Egypt; they carry on their heads two crowns, each appropriate to one of the two great divisions of their united kingdom. That of Upper Egypt is known to egyptologists as the White crown, because of the colour which it bears upon painted monuments; that of the North is called the red crown, for a similar reason. Combined with one another they form the complete regal head-dress ordinarily called the pschent. In the hieroglyphics Northern Egypt is indicated by the papyrus; Southern by the lotus. [Illustration: FIG. 9.--Shadouf; machine for irrigating the land above the level of the canals.] During the Ptolemaic epoch a new administrative division into Upper, Middle, and Lower Egypt was established. The Middle Egypt of the Greek geographers began at the southern point of the Delta, and extended to a little south of Hermopolis. Although this latter division was not established until after the centuries which saw the birth of those monuments with which we shall have to deal, we shall make frequent use of it, as it will facilitate and render more definite our topographical explanations. For the contemporaries of the Pharaohs both Memphis and Thebes belong to Upper Egypt, and if we adopted their method of speech we should be under the continual necessity of stopping the narration to define geographical positions; but with the tri-partite division we may speak of Beni-Hassan as in Middle, and Abydos as in Upper Egypt, and thus give a sufficient idea of their relative positions.
