By reference to this table it will be seen that in 1871, the yield 
per acre increased (except plat 5, which was more badly laid than 
the other plats), as the seed was increased from three-fourths to 
two bushels per acre, while the yield in 1872 seems to bear no 
relation to the amount of seed sown. The maximum yield is 
given by one and one-fourth bushels of seed; next the maximum 
by two and three-fourths bushels, and the minimum by two and 
one-fourth bushels to the acre. No reason can be given for this 
want of uniformity in the results, unless it may be attributed to 
the severe drought of the past summer. Nor is it plain why each 
plat should not have been affected alike, as they lay adjacent and 
nearly upon the same level. 
The Department of Agriculture at Washington sent to the 
University one bushel of Mammoth Bed spring wheat, grown in 
Illinois. This wheat was sown by the side of plats 5 and 6, in 
the above experiment, to test the value of seed brought from 
another locality. One bushel of seed weighed 56 lbs. Sample 
16. Sown May 1st; harvested July 26th. Weight of straw and 
grain, 1,276 lbs. Weight of grain, 230 1-2 lbs. One bushel 
weighs 56 1-2 lbs. Yield per acre, 10.68 bushels. Percentage of 
grain to weight of straw and grain, 25.12. One pound of seed 
yields 5.7 lbs.
