Irrigation in Egypt with shadoofs

Victorian illustration to download showing a picture of men in Egypt operating an irrigation system, shadoofs. A shadoof is a pole on a pivot with a vessel for water at one end and a weight (usually a lump of mud) on the other which raises the water from a river. Here, because the river bank is high, there are 4 tiers of shadoofs which raise the water into a series of troughs until it reaches the top level, where it can be channelled into the fields.
