Note 36 — Chapter I

Thomas Savery was born about 1650, and, in early life, served as a military engineer; he then gave himself to the study of mechanics, and constructed a clock still in existence. He also made a boat with paddle-wheels, turned by a capstan, his object being, as he says, to enable ships to be moved independently of the wind. He next invented what he called his “Fire-machine,” and exhibited it to William III. and the Royal Society in 1699. He applied his engine largely to the pumping out of mines, and, though it was found ultimately to have too little power, and was superseded by that of Newcomen, Savery may fairly claim the credit of having constructed the first really practicable steam-engine. He invented also a very ingenious plan for determining the height of the water in the boiler of the steam-engine, which is still sometimes used.
