seemed desirable to discard those grown in previous years 
that appeared to have no special value or interest. The past 
season 45 hitherto untested varieties, mostly new introduc- 
tions or unnamed seedlings, with 14 grown last season that 
we desired to further test are the only ones we have to report 
upon, with the exception of 66 varieties that have been 
grown successively since 1883. The last series is connected 
with an experiment intended to show how far the relative 
productiveness of varieties can be depended upon through 
consecutive seasons. 
In all cases the seed planted was single eyes ; the rows 
were three and a half feet apart, and the eyes placed one 
foot apart in the rows. The soil, which was in a moderate 
state of fertility, was ploughed in the fall of 1885 and again in 
the spring. No manure was applied, and the ordinary culti- 
vation was given. 
As usual, the reported yield is calculated upon the basis 
of 100 hills. The sorts with ‘‘1885” appended in the table 
were grown last year also; the others have not been pre- 
viously grown at the Station. 
The varieties with the data noted are as follows:
