" GENTLEMEN, " CAMBOBNE, August 19th, 1813. 



" I received yours at Bridgenorth of the 19th July, 

 ordering a steam-engine for rolling sugar-cane. I immediately 

 set the founders to work on one for you, which is to be ready 

 by my return to Bridgenorth about the end of September. I 

 intend to ship it for Bristol, and will call on you on my journey 

 down to Cornwall, as I intend to set it to work at Bristol for 

 your inspection before it is put on board ship. The price I 

 cannot accurately say at present, as the engine now making is 

 on a new principle ; and as it will be more simple in construction, 

 I hope to be able to render it within the price before stated to 

 you. As it is on a new plan I cannot fix the price until I know 

 the cost of making. All I can say at present is that it shall not 

 exceed what I stated to you in my former letter. 



" I remain, Sirs, 



" Your humble servant, 



" ED. TREVITHICK. 



" MESSES. PINNEYS AND AMES, Bristol.'" 



The engine for the sugar plantations in Jamaica, on 

 an improved plan, was to be constructed in the short 

 space of six weeks, and if a saving in cost was effected, 

 the inventor would hand the whole of it to the pur- 

 chaser.

" SlK, " PENZANCE, CORNWALL, March 8th, 1816. 



" I received your favour of the 25th January, but did not 

 answer it in due course, because I was then erecting a very large 

 engine, which is the first on a new plan. This engine, which 

 has been at work about a month, performs exceedingly well. 

 The cost of erection and the consumption of coal are not above 

 one-third of a Boulton and Watt's, to perform the same work.
