Lot Essay

"This book describes an invention for rowing ships in a calm, which Savery patented on 10th January, 1696 (no. 347). Although the invention was well thought of by William III and others, official jealousy prevented its adoption for use in naval ships. Savery was also the author of The Miner's Friend or an engine to raise water by fire (1702) in which he described his experiments on the early steam engine" (Scott).
