166 ReEpoRT OF THE HORTICULTURIST OF THE 
to the green-house, where the warm and moist atmosphere caused 
the eyes to start rapidly, and the others were deposited in a 
cooler part of the cellar. 
On May 9 the tubers of both lots were cut site halves length- 
wise and planted on main plats F 13-16 inclusive, the cuttings 
being placed two feet apart. At this time the shoots on the tubers 
taken from the green-house office were four to six inches long, 
while in those taken from the cellar, the eyes had scarcely started. 
In plats 13 and 14, care was taken not to injure the shoots 
in cutting and planting, but in the other two plats no pains were 
taken in this regard. The crop was harvested October 15. In- 
the following table, the yields of the four rows planted with 
the sprouted tubers and with those not sprouted, are given 
separately for each plat, and at the right the differences in favor 
of each are noted.

Net difference in favor of seed not sprouted .,................. 59 1-4/60 1-4 
As appears, the sprouted tubers yielded less than the others, 
the difference amounting to about one bushel on the area grown— ° 
one-tenth of an acre. This was at the rate of 10 bushels per 
acre for the crop received, or about 84 per cent of the whole 
merchantable yield. This difference, though less than was 
anticipated, is sufficient to justify the rejection of tubers that 
have formed shoots of considerable length for seed. 
The figures indicate that in this case no advantage was gained 
by taking care not to injure, in planting, the shoots that had formed 
on the sprouted tubers.
