On Plaister of Paris. 8t 
Indian corn. On the contrary, our millers sometimes 
damp the wheat, to prevent the bran from being ground 
so fine as to pass through the cloth, and speckle the 
flour. This account is given to shew the effects of mois- 
ture in the English and Irish climate, in comparison 
with that of our country. I believe that plaister will not 
answer so well in a moist, as in a moderately dry cli- 
mate. A very wet season here, is not the most favourable 
to plaistered grounds. The advantages of the gyps, over 
other manures, are most perceptible in dry seasons. I 
doubt, however, be the effects of climate what they may, 
either on products or manures, whether in England, the 
plaister has had a long or fair trial. I find, by some late 
English publications, that. the knowledge of it is not 
extensive, and its use confined to a few agriculturists ; 
some of whom give the most flattering accounts of 
their success in its application. 
Many of my fields are limed as highly as they will 
bear. Some part of my land is fresh; a small part re- 
mains in an exhausted state. I apply the plaister to all, 
and do not find any difference unfavourable to that which 
has been limed. Some years ago, I sowed clover with 
wheat in the autumn, on a field highly limed. I plais- 
tered a part of this field, on the clover and wheat; 
the whole having had a light dressing of dung. The. 
succeeding season, the plaister threw up the clover 
in such profusion as to choak the wheat crop, in a 
great degree. I lost my wheat on the plaistered part, 
as I mowed, not being able to reap, the crop. The 
wheat on the other part was excellent, and the clover 
of moderate growth. I am aware that part of my misfor- 
tune in the loss of the wheat, may be attributed to the
