" alum, silex, calcareous earth, and mag- 

 " nesia, in various proportions, and moist- 

 " ened them with water, he found that no 

 " grain would grow in them ; but when 

 *' they were moistened with water from 

 ** a dunghill, corn grew in them prospe- 

 ** rously." 



These quotations, I presume, will be 

 deemed abundantly sufi&cient, by every 

 unprejudiced reader, to substantiate the 

 argument in support of which I have 

 adduced them, and to give stability to 

 the tenor of my book, for every deduction 

 that we here meet with is clear and con- 

 vincing ; and indeed every result which 

 appears in the whole Treatise, if it could 

 be given in plain English terms, Avould 

 be found to be in true unison with the 

 common conclusions of every experienced 

 farmer.
