~ Having for feveral years paft been in the habit of 
inftruéting pupils in the theory and prattice of agri- 
culture, I have made a point of recommending to 
them the ufe of the drill machine, on a different 
principle than either faving feed or producing a 
greater crop, or any advantage already mentioned; 
for I will venture to affert, that a young practitioner 
in hufbandry will gain more knowledge in the bufi- 
nefs of aration, and the advantages of a well-managed 
fallow, by drilling his crops one feafon, than by 
three years atténtion; aflifted by good inftructions, 
without it. Bad ploughing, bad harrowing, couch, 
clods, and every thing that a good farmer knows he 
ought to avoid or correét, are deteéted by it. The 
teft of good or bad management in every part of his 
field, is immediately under his own hand; he cannot © 
pafs a fingle foot of land in bad tilth without in- 
{tantly perceiving it; and I believe it will be readily 
allowed by every good prattitioner, that whatever 
will obftrué the drill, would annoy the crop to be 
- fown; or in other words, the compleater the pulveri- 
zation of the foil, in general, the more luxuriant will 
be the produce. 
+ Among the advantages of drilling, has been mark- 
_ ed that of ftirring the foil during the growth of the 
crop, and this advantage does not feem to depend 
merely on the pulverization of the foil, put may be 
accounted for by its being kept open at that time, 
‘and in a condition to abforb fome matter from the
