NEW HUSBANDRY EXEMPLIFIED. 59 



' the ear, and its grain ; yet not fo much as 

 " of moft fown wheat, efpecially of the very 

 " early fown, which generally eicapes the 

 ** beft in this common calamity. The burnt 

 " baked wheat being always early fown, I am 

 " informed, had next to no grain in it ; and 

 " this is the moft expenfive fort of Hufbandry,

 " the liberty of ploughing this land. 1 * 



From thefe experiments, and the fuccefs of 

 horfe-hoed wheat upon the author's whole 

 farm, we mufl conclude, that land is enriched 

 from the atmofpheie : for it is evident, that 

 this land had no other afliftance ; and yet, 

 though poor, or very ordinary land, con- 

 tinued year after year, without intermiffion, 

 to produce good crops of wheat, that are ac- 

 knowledged to be exhaufting crops ; fo ex- 

 haufting, that no good farmers will venture 

 to fow wheat on the tame land, for only two 

 years fuccefiively, without manure ; nor with 

 manure, unlefs the land has an intermediate 

 fallow, or a change of fome meliorating crop : 

 fo that horfe-hoeing appears here to be fupe- 

 rior to manure. 



This fertility can be attributed to -nothing 

 elfe but the atmofphere, and to this Mr. Tull 

 does attribute it : for, fays he, p. 63. " If it 

 " (hould be demanded, from whence the foil 

 " can be fupplied with vegetable matter, to 

 ** anfwer what is carried off, by thefe conftant 

 < crops of wheat, that the land be not con-
