Despite the apparent result in favor of whole potatoes, as shown not 
only by the totals, but by each separate trial, we cannot but notice 
that even on the highly fertilized plats of 1882, the yield was below 
that obtained from single eyes in some of the other plats, while in the 
case of the whole potatoes used as seed, the yields in plat I. B. five 
_ were the maximum of all our trials. In view of this observation, as 
also of the uncertainty attending plat experiment, we must consider 
our results as inconclusive for the purposes of generalization, and con- 
clusive only in the fact that, under the conditions of planting and soil, 
ordinary cuts and the whole potatoes showed a marked superiority in 
crop over the single eyes used as seed. 
And these remarks lead us naturally to the subject of duplicates. 
.What variation may be expected between plats presumably of equal 
‘fertility and planted and treated alike? In C. three, C. eight, and 
C. twelve, we have such plats, White Star potatoes, single eyes used as 
seed. The yield from the twentieth of an acre was:

We find in these figures a variation of 39.5 bushels of good potatoes 
between the three yields, and 82.5 bushels on the total crop. 
Let us observe what the variations are between the halves of each 
plat, calculating the yields per aere.
