Bera 
feed for my general market crops the enfuing year, 
are tilled at a diftance from any other potatoe crop, 
and managed as above-mentioned. Since I have 
practifed this mode, which is about feven years, the 
curled difeafe hath not injured my crops. My po- 
tatoes have been better than my neighbours.. In 
the cheapeft time, I never fell under threepence 
per gallon, which weighs ten pounds, or at the rate 
of fix fhillings per fack of 240lb. 
The late crops are the Irith red, or painted’ Lord, 
tilled in April: they produce very plentiful crops, 
_ and continue very good from the beginning of 
December, till the kidneys are fit to draw, which 
is about the firft or fecond week in June. I have 
tilled different ways, fome by drilling about two 
feet apart, and twice or thrice earthed up with the 
double-mould plough: fome in ridges five fect 
wide, leaving between each ridge about 18 inches 
of ground not tilled, which is thrown between the 
plants after hoeing : others I have tilled through- 
out the ficld, about ten inches afunder between 
each plant. Many of this laft tillage get green and 
not fit for ufe. The two former modes anfwer bett 
with me; if the crops are kept clean about 100 
facks in the average. In fome ground I have had 
140 facks per acre. 
I am, Sir, 
Your very obedient fervant, 
JAMES CHAPPLE.
