On Plaister of Paris. 
vi 
“ 
Process. April 8th. Sowed several spbts in my mea- 
a dow with plaister, at the rate of about four bushels per 
acre ; the soil in general a light loam, in parts inclining 
to a gritty gravel, although in parts so flat as to incline 
to stagnate waters; under grass I believe at least fifty 
' years, little or no manure put on it in my memory; 
quantity about five acres, about two whereof is watered 
“with fresh spring water immediately from the spring 
head. Sward a mixture of red and white clover, and 
timothy, with many natural grasses. 
Result. 1788. The improvement at least four fold, 
except in places on which the water stagnated for want 
of fall to carry it off, when I perceived no benefit from 
the plaister ; the clover more improved than the natural 
grasses ; the watered banks as much benefited as the 
unwatered, the water kept of after sowing till the opera- 
tion of the plaister was perceived, after which time 
it was watered as usual. 
Process. 1798. April 6th. Sowed two bushels of plais- 
ter upon the peach lot sown before April 8th, 1788. 
Result 1789. I believe no improvement, but continu- 
ed good. 
Process. April 20th. Finished sowing my meadow 
vith plaister about four bushels per acre ; observations 
April 8th, 1788, in general applicable.
