To the above may be added the yield from Plat F 1, on which ty 
all whole tubers were used for seed, at the rate of twenty-three 
bushels per acre in rows which were continued on from the other 
plats. These tubers were carefully selected of even size, soeach 
set of three rows received exactly eleven and one-half pounds of 
seed. The yield from each lot of seed was : i

This trial is not favorable to the practice of changing seed. 
There was a gain from one lot over home grown seed, but it was | 
more than offset by the smaller yield or tubers from the seed 
grown on sandy land. 
PLOWING up TO PoTaTOES vs. CoMMON CULTIVATION. 
A correspondent of this Station wished some experiments made 
in plowing up to the rows once or twice, but it was too late in the 
season to make a trial on a large scale. There were three twen- 
tieth acre plats available, however, and late as it was, June 
16th, aa were planted with equal amounts of seed put in 
“hills” one and one-half feet apart in the row, while Hie rows 
were forty inches apart. 
They were cultivated once ina row July 9th, and six rows on 
each plat plowed up so as to completely cover the vines. Four 
rows on each plat were hoed without hilling up. 
On July 18th, the potatoes on these plats having made a 
good growth were all cultivated and three of the rows plowed a 
second time. In order to make this work complete, all the parts 
not well covered were hoed up high. These rows looked much 
like well banked rows of celery when completed. 
The number of “hills” in each row were taken at the time both 
plowings were done. The numbering of rows below begins on ~ 
west side for C 1 and on the east for C 2 and 3:
