286 REPORT OF THE FARM SUPERINTENDENT OF THE 
In comparing the green weights it will be seen that in several 
cases where the grass from one plat has an equal or larger yield 
than another, by its greater or less per cent of water content, this 
equality is destroyed or the larger yield reversed when the dry 
matter is considered. Therefore, since we use hay as a dry pro- 
duct, it seems best to make all our deductions on the dry 
matter plus an amount of water nearly proportional with that 
from the other thirty plats. * The water content of hay from these 
plats has therefore been calculated at the average of the above 
thirty 29.825 per cent. 
By referring to the diagram and to the table to note the posi- 
tion and yields from the unmanured plats, it will be seen that the 
extreme yields of dry matter 15.09 pounds is from the plats 6 and 
18 lying nearest together, and that both of the two farthest 
removed plats, 12 and 24, approach very closely to the mean of 
the yields from plats 6 and 18. 
This difference is considerable when regarding the extremes, 
but we may reasonably assume, considering the position and 
yields, that our mean represents as near the average fertility as 
can readily be obtained. If the appearance of greater fertility 
extends in reality to those plats lying adjacent to plat 6, and 
those near plat 18 are relatively as much poorer than the mean as 
that plat is, then the greatest effect of this difference in fertility 
_ will be to exalt the influence of the small applications of fertilizers 
in comparison with the heavier applications which will be to that 
extent underrated. In view of the very variable character of our 
soil and without facts to warrant such a supposition, we are justi- 
fied in using the mean of the four unfertilized plats for comparing 
all the yields from fertilized plats.
