172 THE PRACTICE OF THE 



" to add the following, as a fupplement to my 

 " former letter. 



" However doubtfully I might exprefs my- 

 " felf, in that letter, with regard to the ex- 

 ' cellence of the drill, and horle-hoeing cul- 

 " ture, (not having, as I thought at that time, 

 44 fufficient experience to determine a point 

 " of fo much importance) two years careful 

 " obfervations have fince enabled me to fpeak 

 " more pofitively, and have made me incline 

 " much more to the fide of the drill fyftem. 

 44 Nor have my experiments been confined to 

 " barley. I have cultivated wheat for feveral 

 " years with fucceis, and have applied the 

 *' horfe-hoeing hufbandry to beans, peafe, 

 " oats, turnips, potatoes, fainfoin, and lucern ; 

 *' and the erlecls of horfe-hoeing have been 

 " Ib conflant and uniform in the cultivation 

 " of all thofe vegetables, that I have no doubt 

 " but that this method, if executed with care, 

 " attention, and perfeverance, during a term 

 44 of years, will prove much more advan- 

 " tageous than the old method. 



" The fame field in which the experiments 

 " on barley were made (as before related in 



" ] 7^3> ls uow ^ own w i tn wheat, the eighth 

 " fucceffive crop, of which four crops iiave 

 " been wheat. The two lait of thefe have each 

 " produced two quarters of wheat per acre; and 

 " the land is fo far from being exhaufted by 

 *' fo many burdens, that it leems/yet in per- 

 *' feel heart, though uo manure has ever been 

 " Jaid upon it.
