ImproTfement of arable Land. i6% 

 Layers of Gravel, Sand, Clay, or Chalk ^ an J 

 thefe of all others require an annual or bien* 

 niaf, at leaft a triennial Relief by Compoft, 

 or other Artificial Improvements , and, be- 

 caufe thefe Kinds of Earth are very numerous 

 and extenfive, the Husbandman ought, by 

 all poffible means to apply his Thoughts to 

 find out great Quantiiies and great Varieties 

 of Improvements, either Simple, Compound, 

 or Natural. And the firft I ihail mention a- 

 mongft the Simples is Chalk, if the Ground 

 lie upon a Clay, or Marie, if on a Rock, or 

 fandy, or gravelly Bottom, or as either of 

 them are more lightly or heavily difpos'd, or 

 requires the contrary Qualities of Heat and 

 Cold ; but as thefe two Improvers are not 

 always eafytobe procured, the Husbandman 

 muft ftretch his Confideration yet farther, and 

 procure good Qiiantities of Manure, for 'tis 

 dry barren Land, of which generally moft 

 Farms and Eftates are composed ; and becaufe 

 in thefe (hallow Kinds of Land, there is Sub* 

 ftar)ce wanting, we ought to take care to 

 fleece and pick up ail the Mold we poflibly 

 can out of the High-ways, and other publick 

 and ufelefs Places and Corners, allowing at 

 leaft ^60 Load to an Acre : Let our Compo- 

 fition be then two Load of Turffy Earth, coU 

 lefted as above ; one Load of Pond Earth, or 

 the fcouring of Ditches,- two Load of rot- 

 ten Horfe Dung, half a Load of Cow^s
