is, that pulverized earth, retains the moisture and air,

marks, viz. ‘‘ that sows afforded quantities of air by 
distillation, somewhat corresponding to the ratios of

Inclosed I have sent soils in the state they were found, 
before the courses mentioned were introduced. 
No. 1. A sample of the unimproved soil about three 
inches deep. 
No. 2. A sample of the same soil four inches deep, 
improved by the lime compost two years. 
No. 3. A sample two inches deep from the field in 
its exhausted state. 
No. 4. A sample three inches deep from the same 
field, which was once sown in pasture oats, and has been 
one year in grass sown after the oats, which did not take 
well, partly owing to the late season when it was sown ; 
and partly owing to the seed having been injured, and 
the soil still cold. 
No. 5. A sample two inches from an exhausted field. 
No. 6. A sample four inches from the same field 
after pasture oats, which was followed by wheat, a poor 
crop, and succeeded by oats a middling crop, with 
éelover which yielded a considerable swarth last season ;
