beds, the diseases were completely controlled by using seed
raised in the greenhouse or by using seed from a single ap-

Corn-Soybean Tests. The corn-soybean tests described in
previous reports were completed this year. August was dry
and the competition of the beans reduced the yield of corn
very materially. During the seven years in which these tests
have been conducted, there have been two very good seasons
for corn, two very poor ones, and three fair seasons. Even
in the best corn years, the lightest planting of beans has re-
duced the yield of corn to some extent. In dry years, the
reduction in yield has been very marked. The average yields
for diEerent methods of planting for the 7-year period are as .
