"A contrivance extensively employed in Egypt and the East, generally for raising water. It consists of a long stout rod suspended on a frame at about one fifth of its length from the end. The short end is weighted so as to serve as the counterpoise of a lever, and from the long end a bucket is suspended by a rope. The shadoof is extensively used in Egypt for lifting water from the Nile for irrigation" &mdash;Whitney, 1889 <p>This illustration shows two men using a shadoof to raise water.

"The following description of a section of Lord Rosse's telescope, though not so perfect as could be desired, is the best we could obtain. it exhibits a view of the inside of the eastern wall, with the tube, and machinery by which it is moved. A is the mason-work on the ground; B the universal joint, which allows the tube to turn in all directions; C the speculum in the tube; E the eye-piece through which the observer looks; F a pulley by which the tube is moved; H a chain attached to the pulley, and to the side of the tube; I, a chain running to K, the counterpoise; L, a lever connecting the chain M with the tube; Z another chain which passes from the upper part of the tube over a pulley at W, (not seen) and crosses to the opposite wall; X a railroad on which the speculum is drawn either to or from the tube. The dotted line H, shows the course of the weight R, as the tube rises or falls. The tube is moved from wall to wall by a ratchet wheel at R, which is turned by the lever O, on the circle N, the ends of which are fixed in the two walls." &mdash;Comstock, 1850
