Shaduf

The shaduf was used in Egypt as an irrigation tool. It was made of an upright frame on which was suspended a long pole or branch, at a distance of about one-fifth of its length from one end. At the long end of this pole hangs a bucket, skin bag, or bitumen -coated reed basket. The short end carries the weight (clay, stone, or similar objects to stone) which serves as the counterpoise of a lever.
