There is reason to believe that, under the twelfth dynasty, some derangement of meteoric or atmospheric conditions passed over Abyssinia and Upper Egypt, either in both the directions above noticed, or, at any rate, in the latter and more ordinary one. An official belonging to the later part of this period, in enumerating his merits upon his tomb, tells us, "There was no poverty in my days, no starvation in my time, even when there were years of famine. I ploughed all the fields of Mah to its southern and northern boundaries; I gave life to its inhabitants, making its food; no one was starved in it. I gave to the widow as to the married woman." As the late Dr. Birch observes, "Egypt was occasionally subject to famines; and these, at the time of the twelfth dynasty, were so important, that they attracted great attention, and were considered worthy of record by the princes or hereditary lords who were buried at Beni-Hassan. Under the twelfth dynasty, also, the tombs of Abydos show the creation of superintendents, or storekeepers of the public granaries, a class of functionaries apparently created to meet the contingency."
The distress of his subjects under these circumstances seems to have drawn the thoughts of "the good Amenemhat" to the devising of some system which should effectually remedy these evils, by preventing their occurrence. In all countries where the supply of water is liable to be deficient, it is of the utmost importance to utilize to the full that amount of the life-giving fluid, be it more or be it less, which the bounty of nature furnishes. Rarely, indeed, is nature absolutely a niggard. Mostly she gives far more than is needed, but the improvidence or the apathy of man allows her gifts to run to waste. Careful and provident husbanding of her store will generally make it suffice for all man's needs and requirements. Sometimes this has been effected in a thirsty land by conducting all the rills and brooks that flow from the highlands or hills into subterranean conduits, where they are shielded from the sun's rays, and prolonging these ducts for miles upon miles, till every drop of the precious fluid has been utilized for irrigation. Such is the kareez or kanat system of Persia. In other places vast efforts have been made to detain the abundant supply of rain which nature commonly provides in the spring of the year, to store it, and prevent it from flowing off down the river-courses to the sea, where it is absolutely lost. For this purpose, either huge reservoirs must be constructed by the hand of man, or else advantage must be taken of some facility which nature offers for storing the water in convenient situations. Valleys may be blocked by massive dams, and millions of gallons thus imprisoned for future use, as is done in many parts of the North of England, but for manufacturing and not for irrigation purposes. Or naturally land-locked basins may be found, and the overflow of streams at their flood-time turned into them and arrested, to be made use of later in the year.
