turned into the middle of the intervals by a horfe- 
hoe ; which is the fame with A. CampBeELv’s large 
plough, on a fmaller fcale, with a very narrow earth- 
board. If it be done fooner, there will be danger 
of tearing away thofe which are not feen, if the hoe 
be allowed to come near enough to the reft. If it be 
delayed longer, there will not be the fame benefit 
derived from horfe-hoeing. Any weeds and grafs 
which fhall have efcaped the plough, both now and 
to the time of taking up the potatoes, are carefully 
to be pulled up by the hand. 
In a few days after the firft hoeing, the fame in- 
{trument is to go deeper in the former tra&. This 
ftirring will make the earth in the intervals free, 
that has been trampled down by the weeders, and it 
will bury the weeds they have pulled up. When 
the weeds, buried in the intervals, are rotted or con- 
verted into vegetable food, the earth is returned to 
the plants with a double earth-board-plough, going 
twice in the fame traét with a fhallow furrow ; the 
firft of thefe times down hill; if the Jand be hilly, a 
boy following the plough to uncover any plants that 
have been buried in the row; for, if left in that 
fituation, their growth would be either entirely 
ftopped, or very much retarded. If, by avoiding to 
bury the plants, they fhould be left in fome places 
without any mould touching them, it is drawn to- 
wards them in thofe places with a hand-hoe.
