Thefe potatoes were planted in tows upon dung, 
except where it is otherwife mentioned, and then 
covered up with a double earth-board. In 1790, 
1791, and 1792, the rows were three feet, and in 
1794 and 1795, twofeet and ahalfafunder. This, 
with the difference of feafons, will account for the 
greater produce in the lafttwo years. The diftances 
at which the potatoes were planted in the rows, were 
meafured by a {tick with notches, and taken from 
the centre of the potatoe-fets, Care was taken to 
have the tows as equal in quality of foil as poflible, 
and to have equal juftice done them in manuring, 
where manure was applied, and in horfe-hoeing 
them. The quantity planted and raifed was carefully 
marked in the field by the author of the experiment, 
and no part of the procefs of management was in- 
trufted to any other perfon, 
In the experiments, the acre is the Englifh ftatute 
acre; of 4840 fquare yards; fo that when the rows 
are three feet afunder, 4840 yards of row make an 
acre. When the rows are two feet and half afunder, 
it will take 5808 yards of row to make an acre. 
The bolls and pecks are the Lenlithgow meafure, 
and the Amfterdam Ib, is ufed as a meafure of com- 
pound parts, being the rgth of this peck; the value 
affixed to the potatoes is the price they produce,
