Gwilt translation

2Machines of draft are constructed for the purpose of removing or raising great weights. The scaling machine is one more of boldness than art, being a combination of longitudinal timbers connected together by cross pieces, the splicings well lashed together, and the whole supported by shores or props. But the machine which, by the action of wind, produces very pleasing effects, requires great ingenuity in its construction. The machines for draft perform much greater and more important operations, in their application to different purposes, and, when skilfully managed, are of great utility.

Morgan translation

2In the hoisting class, heavy weights are removed by machines which raise them up and set them in position. The climbing machine displays no scientific principle, but merely a spirit of daring. It is held together by dowels and crossbeams and twisted lashings and supporting props. A machine that gets its motive power by pneumatic pressure will produce pretty effects by scientific refinements. But the hoisting machine has opportunities for usefulness which are greater and full of grandeur, and it is of the highest efficacy when used with intelligence.
