The Schaduff (also Schaduf) + is irrigation equipment that very promptly in the gardens of the old person Egypt and Mesopotamiens were used. A Schaduff consists of a bar, which rests on a support and carries on its longer end on a rope the water tank which can be filled. The worker lifts the short end, to which a counterweight is fastened, and establishes the bucket in the water. Then it presses on the weight, and the filled bucket goes, in order to pour into the Wasserbecken, from that the ditches and channels the water for the fields and gardens to receive. Frequently a somewhat amended device was put also by a course animal, a donkey or ox, into operation. The bucket lowers itself due to its dead weight, then the animal pulls it on a cord, which runs horizontally over a role, again up. The bucket empties itself in the ditch basin and falls then again automatically into the supplying river down there, if the animal returns to its starting point.
Both in the old person Egypt as well as in Mesopotamien was for the development of the garden architecture irrigation a substantial condition. The work of the water drawing was the most labor intensive thereby. As toilsome and labor-consuming the irrigation was, clarifies a text passage from the so-called life teachings of the Cheti, a writer from the 12. Dynasty of the old person of Egypt around 1800:
The gardner carries the yoke; its shoulders are bent as of the age. It has so many ulcers on its neck that this resembles a festering wound. The morning begiesst it in the evening the Schat plants, whereby it falls down all day long in the Obstgarten spend then it dead tired, and more than in applies every other occupation to it
This facilitated itself somewhat with the development of the Schaduffs. In particular in the early advanced cultures Egypt and Mesopotamien could be increased by intensive use of irrigation techniques agricultural production so clearly that also a noticeable increase of the population was possible.
