Excerpt from Notes Screw Propulsion: Rise and Progress Up to this period, the British engineers were nearly unanimous in the opinion, that the use of the Screw involved a great loss of power, and they had concluded that it could not be adopted; but it was impossible any longer to resist the impres sions made on the public by the demonstration which had been given both by Smith and Ericsson; and, although the engineers were still unwilling to admit the screw to a comparison with the paddle, it was evident that their first conclusions regard ing it were erroneous, and thereafter it was Viewed by them with less disdain, and spoken of more hopefully. One of the great objections by engi neers to the use of the screw, was their inability, at the time of its introduction, to construct prop erly a screw engine; that is to say, a direct act ing horizontal engine, working at a speed of from sixty to one hundred revolutions per minute - all their experience having been in paddle-wheel en: gines, working from ten to fifteen revolutions per minute.
