| Description | Written from 18 Duke Street, Westminster, London. The letter explains that although, when Brunel visited Watt & Co's foundry he authorised some changes to the mode of stiffening the slide faces and some other matters, on reflection, he has decided that he was wrong and requests Blake to ensure that the foundry does not touch the slide faces until he can think over it further, and explains not only why his first thoughts were wrong but also the difficulties attendant on stiffening the slide faces. Brunel suggests Blake hold discussions with his workers and offer Brunel any suggestions that they come up with and goes on to list the parameters within which Blake must work regarding the properties of the engines and the challenges that may be faced. The letter also comments on several other matters that Brunel has thought about and finishes with a memorandum titled Memorandum of Drawings Required in Addition to those Previously Mentioned which describes the drawings that Brunel wants to be sent to him. |
