LESSONS ON CORN. ulir4 
The following letter might be sent to all patrons of the school: 
DEAR FRIEND AND PATRON OF THE SCHOOL : 
The teachers and pupils of School, in response to the suggestion of 
the State superintendent, have decided to have, on , a “Corn and Other 
Products Day,” and we cordially invite your cooperation and attendance. Bring 
good samples of corn, fruit, potatoes, tomatoes, poultry, and other home or farm 
products that you care to exhibit, and help us to make it a day of educational 
value. A special program, participated in by the pupils and others, will be a 
feature of the day. 
Please bear in mind that this is your school and that your cooperation and 
presence will be both a help and an inspiration. 
Sincerely yours, 
, Teacher. 
SELECTING THE EXHIBIT FOR CORN DAY. 
The exhibit from one person usually consists of 5 or 10 ears of 
corn. Sometimes a 10-ear exhibit to represent the entire local school 
is made up by selecting that number of ears from the best ones 
brought in by all the members of the school. 
One very important thing to observe in choosing and arranging 
all such exhibits is the principle of uniformity. This is sometimes 
indicated in score cards by the phrase “ uniformity of exhibit.” In 
the score-card form shown on page — it is covered by “ trueness to 
type” and “uniformity of kernels.” These phrases all mean that in 
order to get a high rating all the ears in the set must look alike as 
nearly as possible. A corn judge often discards a set of 5 or 10 ears 
from any further consideration simply because the exhibitor included 
among them one ear that was an inch longer than the rest, or of a 
different shade in color, or that had a different number of rows of 
kernels, or kernels of noticeably different shape or size than those 
on the rest of the ears. Sometimes the size.of cob in one ear differs 
from all the others, or one ear is crooked or has “ twisted” rows of 
kernels, while all the rest are straight. 
Any of these defects spoil the wncformity of the set and cause the 
set to be marked down severely. It is better to select 10 ears that are 
not the very best, but are alzke, than to include one ear that is either 
much better or much worse than all the rest in the set. Pick out the 
best 40 or 50 ears you can find, and then from these, by careful meas- 
‘urement and comparison, select for your exhibit the 5 or 10 that are 
nearest alike. 
The unfavorable impression made by a poorly selected or poorly 
arranged exhibit of 10 ears is clearly illustrated in figures 4 and 6 
(pp. 13,15). Without discarding any ears from the best 10 selected 
they can always be arranged in one best order, from left to right, so as 
to present whatever excellence they have in the most favorable view.
