We said in last year’s report, in discussiong the figures of C. 5, 
“The lesson taught from these tables is that there is certainly no 
inferiority of the seed end when used for seed,” ete. Interpreting 
in like manner the figures for this year, as obtained from D. 7 and 
D. 10, we may say “The lesson taught from these tables is that 
there is certainly an inferiority of the seed end when used for seed.” 
Whence, then, this apparent contradiction ? We believe it proper 
to confess that we have a greater confidence in our facts than in our 
interpretation, and in view of the apparent contradiction we can but 
surmise that our facts last year were discussed in an erroneous man- 
ner. We will, therefore, re-investigate our figures of last year; as, 
however, the number of eyes in each potato are not equally divisi- 
ble by three we must interpolate in order to secure uniformity, and 
hence our figures are not exactly the same as those given in last 
year’s report ; the figures are also changed relatively by counting the 
zeros of the missing hills in calculating the crop. 
Our calculations, therefore, founded upon the data of the two 
years, take this form for the total crop — _ 
Total yield for the butt, central and terminal eyes, in pounds, cal- 
culated to the 100 eyes — &

We must, therefore, reverse our statement of last year, and say 
that the two years’ data go to show that the central eyes of the 
potato are superior in yield to the stem or butt eyes. : 
When a potato is cut into halves, and the butt end and tip end 
are used as seed, we should scarcely expect to find much difference, 
as the errors incident to the plat system may more than counterbal- 
ance such differences as exist. In some plat trials we obtained on 
twentieths of an acre — 
Stem or butt half.
