 tivated soils. Some other i^rass, or crop, for forage, [mil' 

 let I have found the most profitable,) must be substituted, 

 during at least one shift of your rotation : and the land 

 will recover its capacity to produce clover. 



Your reasoning and your practice mentioned in your 

 letter, agree so nearly with my own convictions and ex- 

 perience, that I am under no necessity of enlarging on the 

 subject. 



The plaster never did more on my fields, than it now 

 performs, where it is assisted by the means I mention. 

 Last year it showed little. On my lawn, not ploughed 

 within many years, its effects are wonderful. I strewed, 

 in early spring, a light dressing of live ashes ; with which 

 the plaster co-operates most beneficially. I have cut and 

 secured oS tons of excellent hay, (clover and orchard 

 grass,) off 16 acres of my little fields. I lease the greater 

 part of my farms ; — and my motto is " exiguum colito.''
