ble to the furface in ploughing them up. In one 
purfuit J think I have gained another point, for al- 
though IJ have buried as many potatoes as I raifed 
by it, my ploughman was ftruck with its probable 
utility in wet land, by harrowing it with very little 
addition to the labour of ploughing, and without 
any treading upon it for that purpofe. 
The technical terms of the different parts of a 
plough of this country would probably not apply 
to the inftruments of others; but I think you will 
conceive by the model, that the pin at the point 
keeps it from flipping backwards, and that a crofs- 
bar of iron, which is here called the foot-pin, on 
which the plough-ftick refts, holds this little har- 
row in its place, fo that the teeth pafs fteadily 
through the mould as it is upon the turn, and break 
~ the clods by their own weight more effectually in 
this ftate than any machine, which muft prefs them 
down, would perhaps be able to do at a future 
period, and could not leave the land fo light as 
this does. 
- My ploughman obferved that it made the plough 
draw a little toland; the teeth of mine were made 
round to avoid injuring the potatoes, but were they 
to be made in the form of coulters, and fet with 
the points forwarder, I apprehend they would not 
only pafs eafier through the mould, but might be 
fet fo as to aét in the nature of rudders, and con- 
tribute to keep the plough ftraight.
