The first of these was built at Long Benton Colliery, near Newcastle-onTyne, in 1772.2 It had a cylinder fifty-two inches in diameter. Two others were built in 1775, --one at Chacewater, Cornwall, with a cylinder seventy-two inches in diameter, and the other at Cronstadt, near St. Petersburg, having a sixty-six. inch cylinder.3 The engine at Chacewater (Fig. 26) was the most celebrated of Smeaton's engines.
