| Description | Written from 3 Duke Street, Adelphi. Griffiths invites Brunel, if he has not already decided on the type of screw that he will install in his large vessel, to visit the foundries in Liverpool and Lancashire where Griffiths is overseeing the construction of screws for the Lords of the Admiralty and the United States Navy vessel Preneston. Griffiths also enumerates the advantages of his type of screw over previous designs and requests the opportunity to tender for the making of the screw propeller for the ship. Griffiths also encloses a copy of a letter from Captain B.R. Mathews, former commander of the Great Britain, dated 14 March 1855 which gives Mathews' very positive opinions of how Griffiths' screw functioned on the Great Britain and how much it reduced vibration in the ship and fuel consumption. |
