New Implement called a Cultivator, 21 



In working on a rough fallow, my cultivator mould be fet 

 at its greateft expanfion, and contracted in proportion as the 

 clods are reduced. I am confident that one man, a boy, and 

 iix horfes, will move as much land in a dav, and as effec- 

 tually, as fix ploughs ; I mean land in a fallow ftate, that 

 has been previoufly ploughed. 



It will be requifite in fnme Mates of the foil to alter the 

 breadth of the (hares j but of this, I prefume, the farmer 

 will always be a proper judge. By the expanfion and con- 

 traction of the cultivator, the points of the (hares are, in a 

 Tmall degree, moved out of the direct line; but this is fo 

 trifling, that it is no impediment to its working. I am, Sir, 



Your molt obedient fervant,

Mr. C. Taylor. 



A certificate from Mr. William Shaw, of Cotton End, 

 near Northampton, accompanied this letter ; in which he 

 ftates, that he had ufed Mr. Letter's cultivator upon a turnip 

 fallow laft fummer, and that he believes it to be a very qfeful 

 implement for cultivating the land in a fallow ftate, by its 

 working or fcuffling off feven acres per day, with fix horfes. 

 He adds, that, from its property of contracting and expand- 

 ing, it is calculated to work the fame land in a rough or fine 

 ftate, by which mean it unites the principles of two imple- 

 ments in one ; and, by the index on the axis, it may be 

 worked at any given depth required.

A, the beam. 



B B, the handles. 



C C, a crofs bar of a femicircular form, containing a 

 number of holes, which allow the two bars DD, to be 

 placed nearer or further from each other. 



D D, are two ftrong bars, moveable at one end upon a 

 pivot E, and extending from thence, in a triangular form, to 

 the crofs bar C. In thefe bars are fquare holes, which allow 

 the (hares F, placed therein, to be fixed to any height re- 

 quired. 



The feven (hares marked F, are (haped at their lower ex- 

 tremities like fmall trowels : the upper parts of therh are 

 fquare iron bars. 



GG?are three iron wheels, on which the machine is 

 G, 3 moved ; they may be raifed or lowered at pleafure.
