On Plaister of Paris* 63 



. Result. 1788. Upon mowing both first and second 

 crop, an improvement of at least four times the quanti- 

 ty, and the quality as much improved as the quantity 

 of grass; the trees as apparently improved as the grass; 

 the clover more benefited than the timothy; no percep- 

 tible diiference of improvement in the different soils. 



Process, April 1th. Rainy evening, wind at east, 

 moon's age one day ; sowed a half peck of plaister up- 

 on five perches in the high field ; every observation 

 applicable to April 3d, except the soil being a stilFloam 

 and situation rather level, although high. 



Result. 1789. Spring; as yet no perceptible odds. 

 Fall ; a very perceptible difference ; but the observa- 

 tions of the above may justly be applied to this. As I 

 perceived no difference in the age of the moon when I 

 sowed plaister, I of course discontinued minuting it as 

 a chimera unworthy of notice. 



Process. April Sth. Sowed the peach lot with plaister 

 about four bushels per acre; in cultivation not less than 

 ninety years ; the soil a stiff loam, under stratum a re- 

 tentive clay, sward red and white clover, and green grass 

 fertility of the soil very good ; peach trees just begin- 

 ning to bear. 



Resuh. 1788. An improvement equal to the young 

 orchard ; the peach trees apparently benefited.
