If, then, in a given experiment, we find that the yield of 
cuttings taken from large tubers is less than from whole 
tubers of the same weight as the cuttings, the inference is 
warrantable that the cutting of the tuber was in some 
degree detrimental to the crop. 
On April 27, two rows, each 66 feet long, were planted 
with single eyes of the White Star potato-cut from large 
tubers, and two adjoining rows of the same length were 
planted with small whole tubers, cf which the average 
weight was exactly the same.as of the single eyes. The 
selections were made by first weighing the required num- 
ber of single eyes, and then counting out the same number 
of small tubers, changing the individual tubers until the 
desired weight was secured. 
In the same manner, two rows were planted with two- — 
eye cuttings, and the two adjoining rows with whole tu- 
bers of the same average weight; two rows with three- 
eye cuttings, and the two adjoining with whole tubers as 
before. The rows were 38 feet 10 inches apart, the tubers 
or cuttings one foot apart in therow. Ordinary cultivation 
was given. 
The yields secured were as follows : 
POTATO. 
The yield of Cuttings as compared with that of whole tubers of the same weight.
