Lower Egypt; but as the earth there is marshy, their channels have shifted greatly from age to age and still go on changing. The Nile forms several lagunes near the sea, shut in by long tongues of earth and sand, and communicating with the Mediterranean by openings here and there. The space comprised between the two most distant branches of the river is called the Delta, on account of its triangular form, which is similar to that of a capital Greek delta (Δ)."[1]
At one time the waves of the Mediterranean washed the foot of the sandy plateau which is now crowned by the Great Pyramid; the Nile flowed into the sea at that time slightly to the north of the site upon which Memphis was afterwards built. With the slow passage of time the particles of earth which it brought down from the mountains of Abyssinia were deposited as mud banks upon the coast, and gradually filling up the gulf, created instead wide marshy plains intersected by lakes. Here and there ancient sand ridges indicate the successive water-courses. The never-ceasing industry of its floods had already, at the earliest historic period, carried the mouths of the Nile far beyond the normal line of the neighbouring coasts. The Egyptian priests—whose words have been preserved for us by Herodotus—had a true idea as to how this vast plain had been created, a plain which now comprises twenty-three thousand square kilometres and is continually being added to; but they were strangely deceived when they thought and declared that Menes or Ména, the first of all kings, found almost all Egypt under the waters. The sea, they said, penetrated in those days beyond the site of Memphis, and the remainder of the country, the district of Thebes excepted, was an unhealthy morass.[2] The Delta had, in fact, existed long before the appearance of Menes, and perhaps it may have shown pretty much its present form when the Egyptian race first appeared in the valley of the Nile.[3]
As to the origin of that race, we need not enter at length into a question so purely ethnographical. It is now generally allowed that they were connected with the white races of Europe
