produced six quarters an acre ; succeeded by turnips, nnd 

 bailey, with grasses. 



The instances of the great profit of breaking up old 

 grass, on whatever soil, and under whatever circum- 

 stances (but on dry land being every where superior to 

 Avet), should be combined with the arrangement of a farm 

 in the course of shifts. Upon the poor sands of the 

 southern half of West Norfolk, ray-grass and trefoil are 

 their only dependence : their grand-modicrs trusted to these 

 plants, and the farmers of the present day do the same ; 

 after a year and a half they produce little ; after two years, 

 scarcely any tiling. Thus the land does not get rest 

 enough : when broken up, it has not been sufficiently im- 

 pregnated with the dung and urine of sheep, and the crops 

 consequently are poor.; but if the farmers were persuaded 

 that their future crops would be exadlly proportioned to 

 the stock kept, from the case of a layer of five years to one 

 of 50, they would set themselves to find more durable 

 plants, and bring their waste arable under shifts that should 

 secure very different products. 



The failures in this husbandry of breaking up, have all 

 been for want of paring and burning.
