64 On Plaister of Paris. 



Process. April Sth. Sowed several spots in my mea- 

 dow with plaister, at the rate of about four bushels ])er 

 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 w^ant 

 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 &th. Sowed two bushels of plais- 

 ter upon the peach lot sown before iVpril Sth, 1788. 



Result 11 ^9, I believe no improvement, but continu- 

 ed good. 



Process, April 20th, Finished sowing my meadow 

 with plaister about four bushels per acre ; observations 

 of April Sth, 1788, in general applicable.
