advancement of agricultural knowledge, I have like- 
wife fent an account of the method by which I raife 
much greater crops of that valuable root, as appears 
in the experiments, in foil which you know is far 
from being good. 
Sometime ago I invented a plough, the fock or 
fhare of which is fo formed as to render a coulter 
unneceflary, and is attended with all the advantages, 
without the defects, of that inftrument. It makes : 
the plough fitter for cutting up ftiff land, and it pre- 
vents it from being choaked by ftubble. Were this — 
fock, and a muzzle, or plough-regulator, (likewife of 
my invention) and the common wood-work, added to 
one of the caft-iron bodies, invented by the Rev. 
Mr. Cooxe, and mentioned in the Bath Papers, vol.v. 
page 429, I think it would make a {tronger, a more 
compleat, eafier drawn, and, when ‘the durabi- 
lity -is ‘taken into the account, a cheaper plough, 
and better, fitted for making good work, than any 
that has been hitherto ufed. And if one of thofe 
bodies were fent’ as a pattern to this country, 
the above-mentioned parts of my plough could be 
added to it here: and if on trial it anfwered the 
above expectations, it might be copied by the foun- 
--dery at’ Greenock, and then the. ufe of it become 
general. . “The advantage to the country at large, 
and even'to perfons having fuch intereft in it as you 
have, would probably be greater than I at prefent 
cin bave any couception of. Nor am I without the 
| pleafing
