Weight of grain, 709 1-2 pounds. One bushel weighs 32 1-2 
pounds. Yield per acre, 44.34 bushels. Per cent, of grain to 
weight of straw and grain, 44. One pound of seed yields 15 
3-4 pounds.

The discordant result shown by this experiment is owing to 
the different conditions of the soil, a part of which had been in 
cultivation with corn the previous year, and a part with wheat. 
The experiment shows how difficult it is to get all the condi¬ 
tions of the soil such as to give uniform results, when culti¬ 
vated by the same method. In order that experiments may be 
. reliable, everything must be uniform but the one point which 
the experiment is intended to establish. For example, in the 
above experiment, the only variable element that should exist 
is the amount of seed per acre; all other conditions must be 
the same. It is very difficult to get two adjoining plats that 
have the same degree of fertility, which necessitates the test¬ 
ing of land to ascertain its comparative fertility before using it 
for experimental purposes. 
Value of Well Cleaned Seed. —The following experi¬ 
ment was tried for the purpose of comparing the value of well 
cleaned seed with seed as commonly sowed :
