mezt, on account of the efiluvia that it 
emis ; and that it is defruétive of all 
forts of furniture, fom the fame caufe.— 
2. The afhes have been long ufed’ asa 
manure, attherateof fifty bufhels fpread 
cr fown either on grafs or arable Jand.— ~ 
3. They are laid on-fandy, gravelly, and 
chalky foils; mo commonly for grafles, 
but highly eitcemed as a manure for oats 
or barley. —4. The vegetating effect is fur- 
prizing; it will double or treble a crop of 
any new-fown grafs; it defroys mofs, 
and produces white and Dutchr clover in 
its ftead.
