tion on fertile soils results in strong virile seed of a high 
germination. 
Processing: To insure easy planting and an even 
stand of corn, the seed must be thoroughly and accurately 
graded. Corneli Seed Company maintains one of the 
most modern and complete seed cleaning plants in the 
country and Keystone Hybrids are known for their 
uniform grading. Before shelling, the ears of corn are 
hand picked to remove any inferior or diseased ears 
from the seed. The corn is then processed through 
batteries of machines where it is graded accurately for 
length, width, and thickness. Recent additions to this 
plant are aimed at further increasing the efficiency and 
capacity of the corn grading job. Men who have spent 
most of their lives operating seed cleaning machinery 
are on the job to insure a uniform grade in Keystone 
Hybrids. 
Corneli Seed Company presents their Keystone 
Hybrids for 1942. Two new Keystone numbers — 42 and 
43 — are offered to add to the efficiency of corn produc¬ 
tion. These two, when added to Keystone 38 and Key¬ 
stone 40, form the series of Regular Keystone hybrids. 
In addition to the Keystone numbers, Missouri 8, 
Illinois 960, Missouri 47, U. S. 13, Illinois 21, 200 and 
201 are offered. See the table below for complete de¬ 
scriptions of all of these hybrids. 
The seed of Keystone Hybrids is packed in one- 
bushel bags, and labeled with number, grade, germina¬ 
tion, and production area, and sealed for your protection. 
Do not accept seed if this seal has been broken. 
A tube of Semesan Jr. (1 bushel size) is included in 
each bag.
