436 ON THE FARINACEOUS PRODUCTS 
This amount is so small when compared with 
the quantity used in general by the farmers in 
this neighbourhood, that I have inserted a similar 
column, comprising the results obtained last year 
from eleven varieties. In the Ist or Leigh’s 
Blacks, 1 ewt. of seed yielded 10 ewt., and it re- 
quired 2240 lbs. to produce 104} tons, and nearly the 
same result was obtained in the other varieties. As 
my own sets were planted more closely than is the 
custom of farmers, if 17 ewt. or 1904 lbs. be taken 
it may afford an estimate of the average quantity 
of seed employed by them in a statute acre. — 
An intelligent farmer has informed me, that in 
a very favourable season, 14 cwt. or 1568 lbs. of 
seed produced 114 tons; or 1 ewt. of seed yielded 
16cwt. Another farmer states, that the crop ob- 
tained by him, during an average of several years, 
was 12 tons, from 223 ewt., or 2520 lbs. of seed ; 
or, 1 ewt. of seed produced 11 ewt. 
Mr. Wakefield estimates that in nine agricul- 
tural districts in Ireland, the average crop of 
potatoes, per statute acre, from 1404 lbs. of seed, 
(about 124 cwt.) is 13669 lbs. of produce, or ra- 
ther more than 63 tons. This gives 1 cwt. of 
seed to 10 ewt. nearly.
