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 
xsecommend 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 sufficient 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. l 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
