This “First Cataract,” which makes real navigation very nearly an impossibility,--a vessel can be steered through the rapids only with considerable difficulty and danger,--has always formed the southern boundary of Egypt. Above it, the Nile flows in a great curve through the Nubian sandstone plateau. At numerous places its way is blocked by hard stone material, through which it digs a bed in cataracts. The river valley has throughout no more than a breadth of from five to nine miles. The fertile land, which at the time of the old empire was pretty thickly wooded, confines itself, where it does not cease altogether, to a narrow seam on the banks, so that the inhabitants, in order to leave as little as possible of it unutilised, formed their villages on the barren, unfruitful heights above it. The whole stretch of 1000 miles from Khartum to the first cataract contains at the present day only 1125 square miles of laid-out land. South of the Tropic only, the country on the Red Sea is gradually becoming capable of fertilisation; for the most part, here it bears the character of the Steppes. Also in the Nile, therefore, Egypt is almost totally shut off from Africa. The campaign of the English against the Mahdi has again given us a vigorous picture of how wearisome and difficult is the connection here; of the dangers that a tropical sun, a deficiency of habitations, and the difficulties of communication offer to a small army that tries to advance here. [Illustration: STATUE OF MENEPTAH II, XIXTH DYNASTY (Now in the British Museum)] Egypt is the narrowest country in the world; embracing an expanse of 570 miles in length, it does not contain more than 12,000 square miles of fertile land, that is to say, it is not larger than the kingdom of Belgium. It is necessary to keep this fact clearly in view, especially as the maps accessible may only too easily convey quite a false impression, because they include the desert land within the boundary line of Egypt, and as a rule do not distinguish it by any sign from the fertile land. The ancient indigenous conception is in complete accordance with the geographical character of the land. Egypt, or Kamit, as the country is termed in the indigenous language (the name certainly signifies “the dark country”), is only the fertile valley of the Nile. Here only do the Egyptians dwell. The oases in the west and the “red country” (Tasherit) in the east, _i.e._ the naked, reddish, glimmering plateaus of the Arabian Desert, are reckoned as foreign with consistent regularity, and they are not inhabited by Egyptians. The true state of affairs is quite accurately portrayed in the oracle which decreed, “Egypt is all the country watered by the Nile, and Egyptians are all those who dwell below the town Elephantine and drink Nile water.”
