Double farrow Plough. 171 



A three or four furrow plough may be constructed up- 

 on the same principle with the double furrow plough, 

 but a plough carrying more than two furrows, is more 

 liable to accidents, and rather unwieldy, especially at the 

 turning. 



This plough, it is believed, must become extremely 

 useful in working all sorts of soils, after they are once 

 broken up, and to break up light or sandy soils. But to 

 break up stiff lands, it is apprehended it would take a 

 greater number of horses, than could be managed by the 

 ploughman with convenience. As to working corn and 

 seeding wheat, a fair experiment, for a whole season, up- 

 on a pretty large scale, by the gentleman above alluded 

 to, has proved its great utility beyond a doubt, by ena- 

 bling him to dispense with one-half of his ploughmen and 

 mules for these purposes. 



& A working model, of the improved plough, may 

 be seen in the ware-room of the society.
