28 On Plaister of Paris. 
the next spring, and then mowed two good crops a 
year for two years; then ploughed the clover down, 
after the last mowing the second year, and sowed it 
with wheat on one ploughing, which now isa good 
crop standing on the ground. I may here remark, that I 
have not apprehended the plaister to be of any benefit 
to a crop of wheat, when first sowed, upon it; but after 
having been in with clover, it is ina very fine state for a 
crop of wheat and seldom fails producing a good one, 
if not left to lay so long as other grass, to get too strong 
for the wheat. 
Another experiment I made in part of the field last 
mentioned, on about eight acres that was extremely im- 
poverished, and thrown out of cultivation for a number 
of years. It lay very high and dry. I ploughed it in the 
fall of the year 1791, and let it lay until the next season, 
when I ploughed it again and sowed it with buckwheat, 
which was a light crop, notwithstanding a favourable 
season, not yielding above seven or eight bushels per 
acre. The next spring I sowed it with oats and clover 
seed, and then had five bushels of plaister sowed over 
the whole piece ; the crop of oats better than I expected 
and the clover grew so that it came out in bloom that 
season. The two next seasons I sowed it with plaister, 
the first with but three bushels on the whole, where it 
appeared to be the weakest, the second year with one 
bushel per acre, and mowed the clover both years two 
crops which were good, and the clover appearing to 
stand well. I have sowed it again with one bushel per 
acre, which now promises me another good crop I have 
‘put no other manure whatever upon it, and it 3s now
