Book excerpt: Excerpt from Screw Propellers: And Estimation of Power for Propulsion of Ships; Also Air-Ship Propellers John bourne, in his Treatise on the Screw Propeller, published in 1867, states that the screw propeller is, in all probability, a very ancient contrivance. In China it is said to have been known for ages; but in European countries the idea of a screw propeller appears to have been derived either from the windmill or smoke-jack, or from the screw of Archimedes, an instrument much used in some countries for raising water. Seaton, in his work on screw propellers, traces its develop ment from the time when man first used his hands as paddles, through the pulling oar and the scullin g oar, and the modified application of the latter in the form of the screw propeller.
