One-fourtli of an acre of ground was sown to three-fourths 
bushel by measure of common oats as taken from the bin 
April 22. One bushel of seed weighed 27 1-4 pounds. Har¬ 
vested July 25. Threshed August 18. Weight of straw and 
grain, 864 pounds. Weight of grain, 350 pounds. One 
bushel weighs 33 1-2. Yield per acre, 43 3-4 bushels. One 
pound seed yields 17.2 pounds. Per cent, of grain to weight 
of straw and grain, 40.5. 
An equal area was sown at the same time to three-fourths 
bushel by measure of common oats, well cleaned. One bushel 
of seed weighed 30 pounds. Harvested July 25. Threshed 
August 18. Weight of straw and grain, 910 pounds. Weight 
of grain, 386 1-4 pounds. Weight of one bushel, 35 1-2 
pounds. Yield per acre, 48 1-4 bushels. One pound of seed 
yields 17.1 pounds. Per cent, of grain to weight of straw and 
grain, 42.4. 
The only difference in the cultivation of these two plats, 
was cleaning the seed of the latter of all chaff and light 
grain. The effect of cleaning, as shown by this experiment, 
amounts to 4 1-2 bushels of grain per acre, a measured bushel 
of which weighs two pounds more than that of the uncleaned. 
Had heavier oats been used, the difference would probably 
have been less. 
A plat of one-fourth of an acre adjoining the above plats 
was sown at the same time to three-fourths bushel by measure 
of a mixture of equal parts of White and Black Norway, 
Surprise, Potato and common oats, weighing thirty-two 
pounds per bushel. Harvested July 25. Threshed August 
18. Weight of straw and grain, 964 pounds. Weight of 
grain, 357 pounds. Weight of one bushel, 34 1-2 pounds. 
Yield per acre, 44.7 bushels. One pound seed yields 14.9 
pound?. Per cent, of grain to weight of straw and grain, 37.
