* It is supposed that in England in general, the common 

 breadth of the furrow-slice, is about nine inches ; but from the 

 shallow ploughing which the generality of the farmers in 

 Norfolk, for various reasons, prefer, their furrow-slices are 

 full eleven inches broad ; so that the quantity of the ground 

 stirred in the same number of hours work by them, must bs 

 considerably more than farmers in other districts can do, 

 where the natnre of the soil requires to have the furrow-slice 

 f a narrower breadth.
