Nevertheless, throughout that desert, and neglected wilderness, the Nile has flowed for ages, and the people upon its banks are as wild and uncivilized at the present day as they were when the Pyramids were raised in Lower Egypt. The Nile is a blessing only half appreciated; the time will arrive when people will look in amazement upon a mighty Egypt, whose waving crops shall extend, far beyond the horizon, upon those sandy and thirsty deserts where only the camel can contend with exhausted nature. Men will look down from some lofty point upon a network of canals and reservoirs, spreading throughout a land teeming with fertility, and wonder how it was that, for so many ages, the majesty of the Nile had been concealed. Not only the sources of that wonderful river had been a mystery from the earliest history of the world, but the resources and the power of the mighty Nile are still mysterious and misunderstood.
In all rainless countries, artificial irrigation is the first law of nature, it is self-preservation; but, even in countries where the rainfall can be depended upon with tolerable certainty, irrigation should never be neglected; one dry season in a tropical country may produce a famine, the results of which may be terrible, as instanced lately by the unfortunate calamity in Orissa. The remains of the beautiful system of artificial irrigation that was employed by the ancients in Ceylon, attest the degree of civilization to which they had attained; in that island the waters of various rivers were conducted into valleys that were converted into lakes, by dams of solid masonry that closed the extremity, from which the water was conducted by artificial channels throughout the land. In those days, Ceylon was the most fertile country of the East; her power equalled her prosperity; vast cities teeming with a dense population stood upon the borders of the great reservoirs, and the people revelled in wealth and plenty. The dams were destroyed in civil warfare;the wonderful works of irrigation shared in the destruction; the country dried up; famine swallowed up the population; and the grandeur and prosperity of that extraordinary country collapsed and withered in the scorching sun, when the supply of water was withdrawn.
At the present moment, ten thousand square miles lie desolate in thorny jungles, where formerly a sea of waving rice-crops floated on the surface; the people are dead, the glory is departed. This glory had been the fruit of irrigation. All this prosperity might be restored: but in Egypt there has been no annihilation of a people, and the Nile invites a renewal of the system formerly adopted in Ceylon; there is an industrious population crowded upon a limited space of fertile soil, and yearning for an increase of surface. At the commencement of this work, we saw the Egyptians boating the earth from the crumbling ruins, and transporting it with arduous labour to spread upon the barren sandbanks of the Nile, left by the retreating river; they were striving for every foot of land thus offered by the exhausted waters, and turning into gardens what in other countries would have been unworthy of cultivation. Were a system of irrigation established upon the principle that I have proposed, the advantages would be enormous. The silt deposited in the Mediterranean, that now chokes the mouths of the Nile, and blocks up harbours, would be precipitated upon the broad area of newly-irrigated lands, and by the time that the water arrived at the sea, it would have been filtered in its passage, and have become incapable of forming a fresh deposit. The great difficulty of the Suez canal will be the silting up of the entrance by the Nile; this would be prevented were the mud deposited in the upper country.
