else (not a fallow, but) a fallow crop i and high manuring for a 
potatoe crop precedes wheat. 
3dly. By fallow-crops ; fallows for the destruction of weeds 
being nearly given up all over the kingdom. A fallow crop, is 
one that will admit, and will require the ground in the intervals 
to be kept constantly free from weeds by hand hoeing, or hand 
weeding, like potatoes. 
4th ly. By making the grass land subservient t© the arable. 
That is, so proportioning the meadow and the arable, that, the 
cattle fed on the former will supply dung enough to manure about 
one fourth of the whole farm every year. 
But where, notwithstanding every precaution in collecting 
dung, and forming compost heaps, manure is scarce ; as it always 
will be where the farm has too large a proportion of arable land, 
and the farm is understocked with sheep and cattle ; then recourse 
is had to ploughing'-in a green crop. This practice I have seen 
pursued now and then with much pleasure in Pennsylvania, where 
buckwheat is the crop usually ploughed down when just coming 
into flower. In England, the common plant used for this purpose 
is the tare or vetch vicia, sativa, aulgaris. But the common 
plough, either of England or this country, is inadequate to the per° 
formance of this very useful part of farming, with neatness and 
effect. I therefore present my readers with a plate of Mr. Due- 
kefs skim-coultered plough, which, gained the premium given by 
the Duke of Bedford, as well as the gold medal of the Board of 
Agriculture. It is taken from the 43d voh of the Annals of Agri» 
culture, for the year 1805. The editor of that work observes very 
justly that, “To think of attempting to plough-in any green crop 
by way of manure, or a long stubble, or the plentiful fragments 
left of a crop of tares, or weeds, or long dung, (with the common 
plough) is an idle expectation : no other plough will effect it. 
But this instrument executes the work in perfection. The skim, 
is applicable to any plough,” T. C,
