XXXVI. Method of raising large Stones out of the Earth. 

 By Mr. Robert Richardson, of Kesivicft, in Cum* 

 herlana)*. 



GENTLEMEN, 



I, Robert Richardson, of Keswick, in the parish of 

 Crosthwaite, and county of Cumberland, beg leave to in- 

 form you, that I have found out a method of taking large 

 self-stones out of the ground in a very expeditious manner, 

 and that by this means two men will take as many stones 

 out of the ground in one day, as would require twelve men 

 in the usual way of blasting, and afterwards using large 

 levers, &c. 



Where stones of from two to four tons each are to be 

 taken up, two men will raise as many as twenty men in the 

 usual way. The work is done by the power of a tackle, but 

 by my method of fixing the tackle to the top of the stone, 

 by the plug which T have invented, it will hold till the stone 

 is pulled out of the ground, and laid upon the surface, or 

 upon a carriage, if required, all which can be done in a very 

 little time. 



Stones of four tops weight, or upwards, may be taken 

 out of the ground within the time of five or ten minutes, 

 by two men, without any earth or soi! being previously 

 taken from around them, or without any digging with hacks 

 or spades. J. C. Curwen, esq., of Workington, has seen 

 and approved of my performance with this invention, and 

 if the Society should think it deserving of a premium, it 

 would ever be gratefully acknowledged by, 



Gentlemen, your most obedient humble servant, 



Robert Richardson. 



Keswick, Feb. 8, 1808. 



To the Society of Arts, &c. 



PEAR SIR, 



I cannot suffer Mr. Richardson's letter to be sent to the 



* From Transactions of the Society for the Encouragement of 'Arts, Mannfac- 



tures, and Commerce, for 1808. The silver medal of the Society was voted 



to the inventor, and one of the implements is preserved in the Society's Re- 

 pository.
