The full stand of corn should have been seventy-six plants to the 
row, of potatoes sixty-six hills to the row. Correcting for the defi- 
ciencies and calculating to the plat of nine rows, we have

~ The eight corn plats, which may be considered duplicates, yielded 
per plat 200.7 lbs. sound and 6.6 lbs. unsound corn, the extremes for 
sound corn being 161.1 lbs. and 287.0 Ibs. | 
The twenty potato plants, which may be considered as duplicates, 
yielded in the average 490.5 lbs. merch. and 524.8 lbs. total per 
plat. The extreme yields of the plats were 294.9 lbs. and 639.2 lbs. 
for merchantable, 330.7 and 670.2 Ibs. for total crop. 
We may now compare our figures arranged in tabular form :

We thus see that in the mixed plats the corn yielded more than 
the duplicate plats, the potatoes less. Even if we make ample al- 
lowance in our mind for the increased spacing, we can see no evi- 
dence that the potatoes were injurious to the yield of the. corn. 
On the contrary the potatoes seem to be injured greatly by the corn, 
and this is shown by the great increase in the percentage of unmer- — 
chantable potatoes to the merchantable crop. As the corn plant and
