Description

Engraving after a drawing by inventor Robert Fulton (1765-1815), from his 'A treatise on the improvement of canal navigation' (London, 1796). Here boats are raised by using pivoted cranes to lift them and swing them into the upper canal. Many canals were built in England in the late 18th century. Fulton was convinced that expensive locks and aqueducts were not necesary. He believed it would be cheaper to use small canals with inclined planes between different levels and cable viaducts over rivers. 'Tub and cistern' lifting motors provided the power. He also discused designs for iron and wooden bridges.
