Yet this difference is no more than is often found between dupli- 
cate plats, and yet it is about double what occurs between plats D. 
12 and D. 14, and still more than exists between plats D. 11 and

Massing these with our other results and we have five trials, of 
which three are in favor of the stem end, and two of the butt end, 
or in total yield of the five trials the seed end is slightly in advance. 
“We may hence conclude that the trial does not decide a difference 
between the values of the two ends of the potato as used for seed, 
but simply determines in terms of greater or less that the central 
portion of the potato yielded the best results when used for seed. 
The next problem we shall seek to elucidate is that of the imflu- 
ence of the character of the seed used, understanding by this, single 
eyes, small cuttings or whole potatoes. As we have already observed, 
we have no means of determining duplicates, and hence we must 
devise other methods for obtaining our results than that of the com- 
parison of adjoining crops, which vary from each other no more than 
do those plats which were intended as duplicates. 
For the purposes of our study we have twenty plats where single 
eyes were used for seed, eight plats with quarter potatoes, five with 
half potatoes and three with whole potatoes. In every case the fer- 
tilization of the preceding year was the same, viz., 400 pounds super- 
phosphate per acre. In all but a few cases the method of treatment 
during growth was the same, and the variety in all cases the White 
Star." In a few cases three kinds of seed were grown in alternate
