VARIOUS INVENTIONS. 3 



" I think the steam would answer a good purpose around the 

 outside of the pan. 



"If this method answers, the cost of working the engine 

 would be nothing, and the engine would be then working, as it 

 were, without fire or water. 



" The Spaniards told me that if this plan answers, they would 

 take a thousand engines for South America and the Spanish 

 West Indies. I shall be very much obliged to you for your 

 opinion on this business. These merchants make a trade of buying 

 up sugar mills and pans, with every other thing they want from 

 England, and exchange them with the Spaniards for sugar. 



" At Manchester I found two engines had been made and put 

 to work ; they worked very well : three more are in building. 

 From there I went to Derbyshire. The great pressure-engine 



1 expect will be at work before the middle of October. A 

 foundry at Chesterfield is building a steam-engine as a sample ; 

 two foundries in Manchester are at full work on them, and one 

 in Liverpool. There are six engines nearly finished at Coal- 

 brookdale, and seven in a foundry at Bridgenorth. 



"I am making drawings for several other foundries. Any 

 number of them would sell. A vast number are now being 

 erected, and no other engine is erected where these are known. 

 The engine for the West India Docks was neglected during my 

 absence from the Dale, but I expect it will be ready to send off 

 in ten days. 



" In about three weeks I shall be in London to set it up. It 

 will please you very much, for it is a very neat and complete 

 job, and I have no doubt will answer every purpose exceedingly 

 well. At Newcastle I found four engines at work, and four 

 more nearly ready ; six of these were for winding coal, one for 

 lifting water, and one for grinding corn. 



" That grinding corn was an 11-inch cylinder, driving two 

 pair of 5-feet stones 120 rounds per minute ; ground 150 

 Winchesters of wheat in twelve hours with 12 cwt. of small 

 coal. It worked exceedingly well, and was a very complete 

 engine, only the stroke was much too short, not more than 



2 feet 6 inches, which made very much against the duty. 



" The other engine that was lifting water had a 5J-inck
