new pump was needed there and this allowed Symington to develop what he called a 'lifting engine'. He may have built one of these for the Wanlockhead mines in 1789. The Callendar venture ended badly, however, and, in a dispute at the High Court in Edinburgh that lasted until 1810, Symington lost. Last years Due to Patrick Miller's unwillingness to pursue the potential of the 1789 trial, the loss of interest from Lord Dundas and the proceedings at the High Court, Symington was left out-of-pocket. In 1829, in ill health and in debt, Symington and his wife moved to London to live with their daughter and her husband. Symington died in 1831 and was buried in St. Botulph's churchyard. In 1890, a bust was unveiled in Edinburgh, in what is now the National Museum, in memory of the great engineer. References Harvey, W.S. & Downs-Rose, G. (1980).
