Calculating the yield of sound corn to the acre in bushels of eighty 
pounds of ear corn, we have —

In order to understand these figures we must see whether the varia- 
tion is greater or less between these separate plats than between the 
individual plats. Harvesting each plat in two portions, and calculat- 
ing the yields per acre, we have —

Ag the variations between the plats are greater than the variations 
between their half-plats, it seems evident that there is a difference of 
soil which prevents the plats being considered as duplicates, and D. 
one and D. two are no exception to this rule. If these plats be con- 
sidered as four of half size, we have for yield from left to right, fifty- 
eight bushels, fifty-five bushels, forty-seven bushels, fifty-one bushels, 
which order of figures confirms our conclusions. 
It is thus seen that we have no reliable data for interpreting the 
yields from corn planted at various distances, and that only when the 
variations are very large can we be justified in claiming a true 
difference to be ascribed to the planting, and this only in terms of 
greater or less. 
In D. two we had hills 42 x 44 inches apart, in D. four hills 21x 44 
inches apart, and in D. three hills 44x84 inches apart. ‘The yields 
were of sound corn —

We see here no gain in crop through the closer planting, but less in 
crop from the distant planting. , 
What these figures mean I hardly know for D. six, a duplicate of D. 
two, except that pig weed was sown in the intervals on July 2, yielded 
two hundred and forty-seven pounds and three ounces of sound corn, 
or 61.8 bushels per acre, exceeding D. two by twelve bushels, D. one 
by five bushels. Unless we are prepared to assert that the gain over 
D. two was produced by the presence of weeds, we hardly should claim
