both the best and poorest hills of these varieties were cut to 
single eyes and planted as described in our reports for 1884 
and 1885*, the planting being done April 30. 
The yields calculated per eye in ounces, were as follows:

It is evident from the table that the results are less uni- 
form than were those of the same experiment in the pre- 
vious two seasons, and in some respects appear to contra- 
dict the hypothesis that has been so well sustained. The 
largest yield secured comes from the smallest hill, while in 
two out of four cases, the smallest tuber yielded more than 
the largest. Taking the average of the two tubers of each 
hill, however, the results are clearly in favor of the largest 
hills in both varieties. It should be remembered, that in 
some cases in this planting, the largest tuber was lost by 
decay. This experiment adds nothing to the testimony of 
1884 and 1885. It is presented only for the purpose of 
making the report of results complete. 
For experiments in this line next season, the largest and 
smallest hills from 124 varieties and seedlings of the potato 
have been selected ; beside sufficient seed of the White 
Star variety to plant many field plats. It is to be hoped, 
therefore, that the results of 1887 in this line, may be con- 
sidered as conclusive. A 
IS CUTTING THE TUBER, IN ITSELF, DETRIMENTAL ? 
In the majority of our experiments made with large and 
small tubers, the yield has been largest from the former.
