And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

A complete propeller assembly at Wallsend Slipway & Engineering Co. for the “Mauretania”
It is called a screw. Airplanes have propellers (or so my old Chief told me).ReplyDelete
Parsons Marine Steam Turbine Company was a British engineering company based on the River Tyne at Wallsend, North East England.ReplyDelete
Charles Algernon Parsons founded the company in 1897 with £500,000 of capital. It specialised in building the steam turbine engines that he had invented for marine use.
73,000 horsepower (54,000 kW) Parsons turbines powered the 31,000 GRT Cunard express ocean liners RMS Mauretania and RMS Lusitania.
... All early marine turbines drove their propellers directly.
... The company was absorbed into C. A. Parsons and Company and survives in Heaton, Newcastle as part of Siemens, a German industrial conglomerate.
