56 Varivus Modes of Planting the Potato, 
30 feet: the potatoes were then dug out, weighed, and 
counted. 
The accompanying Table will show the results.—The first 
column of the Table is merely the number of the experiment ; 
the second shows the number of sets taken up ; the third the 
distance between the ridges; the fourth the distance between 
the sets in the ridges; the fifth gives the total weight of 
potatoes taken up; the sixth the number of potatoes; the 
seventh is formed by dividing the total weight by the number 
of sets, and gives the average weight from each set ; the eighth 
is formed by dividing the total number of potatoes by the 
number of sets, giving thus the average number of potatoes 
to each set. The average weight of each potato, as shown 
in the ninth column, is found by dividing the average weight 
of the set by the average number of potatoes at each root, or 
it may be got by dividing the total weight by the whole 
number of potatoes ; the tenth column shows the number of 
sets to the acre; and the eleventh gives the weight of the 
produce per acre, as deduced from the measurements made 
and weights taken. 
Considered as an experiment, the results are inconclusive 
as to the best mode of planting potatoes ; but there is, 
nevertheless, some valuable information gained. Itis evident 
from the first seven experiments, when the ridges were drawn 
from 2 ft. 7 in. to 8 ft. distance, and the sets from 1 ft. 8 in. to 
3 ft. apart, that the average size of the potato far exceeded 
that given by the latter experiments, where the distance be- 
tween the ridges was rather less, and the spaces between the 
sets varied from 123 to 21 inches. 
The average of the first seven experiments gives for the 
weight of each potato 4°013 ozs. ; the average of the five last 
experiments gives for the weight of each potato 1°61 oz., or 
not much more than one-third of the weight of the former.
