This vegetation, now wholly regulated and controlled by the hand of man, must have been, in its original and primeval state, of a very peculiar character. It must have consisted of such plants only as could exist under the condition of having the soil in which they grew laid, for a quarter of the year, wholly under water. This circumstance, probably, prevented the valley of the Nile from having been, like other fertile tracts of land, encumbered, in its native state, with forests. For the same reason, wild beasts could never have haunted it. There were no forests to shelter them, and no refuge or retreat for them but the dry and barren desert, during the period of the annual inundations. This most extraordinary valley seems thus to have been formed and preserved by Nature herself for the special possession of man. She herself seems to have held it in reserve for him from the very morning of creation, refusing admission into it to every plant and every animal that might hinder or disturb his occupancy and control. And if he were to abandon it now for a thousand years, and then return to it once more, he would find it just as he left it, ready for his immediate possession. There would be no wild beasts that he must first expel, and no tangled forests would have sprung up, that his ax must first remove. Nature is the husbandman who keeps this garden of the world in order, and the means and machinery by which she operates are the grand evaporating surfaces of the seas, the beams of the tropical sun, the lofty summits of the Abyssinian mountains, and, as the product and result of all this instrumentality, great periodical inundations of summer rain. For these or some other reasons Egypt has been occupied by man from the most remote antiquity. The oldest records of the human race, made three thousand years ago, speak of Egypt as ancient then, when they were written. Not only is Tradition silent, but even Fable herself does not attempt to tell the story of the origin of her population. Here stand the oldest and most enduring monuments that human power has ever been able to raise. It is, however, somewhat humiliating to the pride of the race to reflect that the loftiest and proudest, as well as the most permanent and stable of all the works which man has ever accomplished, are but the incidents and adjuncts of a thin stratum of alluvial fertility, left upon the sands by the subsiding waters of summer showers. The most important portion of the alluvion of the Nile is the northern portion, where the valley widens and opens toward the sea, forming a triangular plain of about one hundred miles in length on each of the sides, over which the waters of the river flow in a great number of separate creeks and channels. The whole area forms a vast meadow, intersected every where with slow-flowing streams of water, and presenting on its surface the most enchanting pictures of fertility, abundance, and beauty. This region is called the Delta of the Nile.
