On Plaister of Paris, 



less injurious to the soil; by not being trodden the clover 

 will stand good longer and will not get into that tough 

 state above described. It should never lay more than two 

 years until ploughed for a crop of wheat, and I would 

 recommend the following rotation of crops, as requiring 

 the least ploughing or labour, and which I am endea- 

 vouring to practice. First year Indian corn, potatoes 

 and pumpkins ; second year barley, when it should be 

 manured and plaistered, after being sown with clover ; 

 third year clover, to be mowed and given to the stock, 

 or made into hay ; fourth year to be used in the same 

 manner, and ploughed after the second crop is mowed 

 for wheat ; fifth year wheat. The two years it is in clo- 

 ver, it should be plaistered with one bushel per acre, 

 if high and loamy land, but more if inclined to be heavy. 



If five fields are farmed in this manner, the produce 

 will be amply sufiicient to manure one of them every 

 year. I have somewhat deviated from the query, to 

 shew the little danger their is to be apprehended from 

 a proper management, where the plaister is used. 



Query 7. To what products can it be best applied? — 

 grain and what kinds ? — grasses and what kinds ? 



Answer, I have found it more beneficially applied to 

 Indian corn than any other grain, having never failed 

 to have a good effect wherever I have applied it, except 

 in two instances ; one of them was in a field about a third
