No. 33.] 123 
The total number of eyes planted was five Hundred and eighty-two, 
and of these sixteen from the stem-end, five from the center, and four 
from the seed-end failed to grow. 
The total crop 388.77 pounds of good potatoes; 86.23 pounds of 
small potatoes, and 192.62 pounds which were rotten. By multiplying 
by twenty the yield per acre will be obtained. In order to get figures 
which can be readily compared, we calculate the yield per one hundred 
eyes, or one hundred hills, and this may be represented by the follow- 
ing tables:

The four eyes from the extreme seed end of these same potatoes, cal- 
culated in like manner, yielded per hundred eyes, two hundred and 
thirteen good, two hundred and seventy-two small, one hundred and 
fifty rotten —total, six hundred and thirty-five potatoes, and the 
weights were 82.55 pounds of good, 20.33 pounds of small, and 40.32 
pounds of rotten — total, 143.20 pounds. 
The lesson taught from these tables is that there is certainly no infe- 
riority of the seed end when used for seed. On the contrary, the fig- 
ures not only absolutely, but relatively show a distinct advantage for 
the seed-end eyes in weight and crop while the figures do not show the 
same advantage in the number of good potatoes. That. this relation 
is not an accidental one is made clear by the calculation of the yield 
of the four extreme eyes from the seed end, which give figures yet more 
favorable. . 
Indeed, the general summary of our experience with the potato, as 
heretofore represented, as well as the result of the present experiment, 
goes to show that the vitality of the eyes used as seed improves accord- 
ing to the position they occupy upon the potato toward the terminal 
position. 
During the season of growth the plants from the central eyes showed 
slightly more vigor of growth than did those plants from the ends of 
the potato. This fact was, however, so little marked that it could 
only be observed by taking a comprehensive glance over the plat which 
showed aslight undulation from the, in general, greater size of the cen- 
tral plants of the potato. 
The variety used was the White Star, and it will be noted that the 
amount of rot was quite excessive, and indeed this rot seems to bear 
but an accidental relation to the position of the eye used as seed. It 
was impossible to obtain the true weights of the potatoes yielded on ac- 
count of the destruction of some by the rot, involving a loss of weight, 
but, so far as our judgment could determine, any changes made by the 
rot would not seem to invalidate the relations of the figures as given.
