"It is my opinion that every part of agriculture might he 

 performed by steam ; carrying manure for the hind, ploughing, 

 harrowing, sowing, reaping, thrashing, and grinding; and all 

 by the same machine, however large the estate. 



" Even extensive commons might be tilled and effectually 

 managed by a very few labourers, without the use of cattle. 



" Two men would be sufficient to manage an engine, capable 

 of performing the work of 100 horses every twenty-four hours ; 

 requiring no extensive buildings or preparations for labourers or 

 cattle, and having such immense power in one machine as could 

 perform every part in its proper season, without trusting to 

 labourers. 



" I think a machine that would be equal to the power of 100 

 horses would cost about 500Z. 



"My labour in invention I would readily give to the public, 

 if by a subscription such a machine could be accomplished and 

 be made useful. 



" It would double ihe population of this kingdom, for a great 

 part of man's food now goes to horses, which would then be dis- 

 pensed with, and so prevent importation of corn, and at a trifling- 

 expense make our markets the cheapest in the whole world ; 

 because there are scarcely any coals to be found except in Eng- 

 land, where the extreme price, duty included, does not exceed 

 2s. per bushel. 



" I beg your pardon for having troubled you with such a wild 

 idea, and so distant from being carried into execution ; but 

 having already made the experiment before stated, which was 

 carried out in the presence of above 10,000 spectators, who 

 will vouch for the facts, I venture to write to you on the 

 subject, for the first and only self-moving machine that ever 

 was made to travel on a road, with 25 tons, at four miles per 

 hour, and completely manageable by only one man, I think 

 ought not to be dropped without further experiments, as the 

 main point is already obtained, which is the power and its 

 management, 



" Your most obedient servant, 



" RICHARD TUEVITHICK."
