HENRY FIELD’S SEED SENSE FOR MARCH, 1940—Henry Field Seed & Nursery Co., Shenandoah, Iowa. 
ONLY 20,000 BU. MULE-HYBRID LEFT! 
RUSH YOUR ORDERS BEFORE APRIL 1st . .. 
ENORMOUS DEMAND REDUCING OUR SUPPLIES FAST 
Everywhere, it seems they’ve heard of Mule-Hybrid corn! The way the orders 
have been pouring in, it looks like our stocks won’t last to planting time. Not only 
the folks who bought last year, but their neighbors and friends who saw the enormous 
yields of Mule-Hybrid are coming in for their corn, too. While it lasts, it’s first come 
first served. 
CORN-FREIGHT PAID 
Don’t let anyone tell you freight on corn is expensive. It isn’t. Just to prove it, 
for 25c per bushel on my Mule-Hybrid corn, I’ll pay the freight anywhere in Iowa, 
Missouri, Kansas, Illinois, Minnesota, Nebraska, and South Dakota. And for 50c per 
bushel. I’ll pay the freight into any other state. Just add that amount per bu. to your 
order and say, send freight paid. 
GUARANTEED STAND! 
For only $1 per bu. extra, I’ll Guarantee Your Stand of Corn and Pay the Freight 
to Your Town. Even with this stand insurance added, your corn costs little more than 
open pollinated corn and way less than other hybrids. 
YOU MUST BE SATISFIED OR NO TRADE 
I guarantee to please you. If the shipment doesn’t suit you in every way, fire it 
back. I’ll pay the freight and send you corn that will please or refund your money. 
This corn is good, will please you and that’s why I can write a guarantee like that

State Certified Hybrids 
Yes, we have State-Certified 
hybrids, too. Some seedhouses sell 
these exclusively as they have none of 
their own and state hybrids are 
available to everyone. We ask less 
for them as we feel Mule-Hybrid is 
far superior. It takes 5 yrs. to get a 
breeding improvement into State- 
Certified seed. With Mule -Hybrid, 
we can add these improvements right 
away and do. This puts Mule-Hybrid 
years ahead of State-Hybrids in these 
improvements. Prices on price list 
enclosed. 
Actual Tests Show— 
My “Weathr-Proofed” 
Blends Yield from 6 to 
8 hu. per A. MORE than 
one hybrid planted 
alone. Pollenizes over 
20 day period—thereby 
pollenixing despite hot 
days. 
S The New Way to Plant Corn! 
NOW! "WEATHER-PROOFED" MULE-HYBRID CORN BLEND 
• Throws Pollen Over Long Period • Pollinates Silks Despite Hot, Dry Winds 
• Insures Better Corn Crop 
See If this doesn’t sound like common sense to you! Everyone knows that if there is no pollen, 
there is no corn. Ordinarily growing corn sheds its pollen only during a period of 3 or 4 days. 
What happens if a hot wind happens to come along that particular time? There is no corn, or the 
yield is cut way down because it dries up the pollen and it can’t fertilize the silks! 
But the silks remain receptive to fertilization for 20 days. The ideal arrangement is to have 
pollen falling on them during most of this period. Then if a hot wind comes, for 4 or 5 days, it can’t 
harm the corn yield. There will be more pollen coming. 
New Blend Discovered! 
We’ve done just that! By careful selection, and blending of selected hybrids we have a blend that 
will throw pollen over period of 20 to 25 days. If hot winds come, the corn will still throw pollen, enough 
to fertilize the silks and save the corn yield. 
Actual Tests Prove It Works 
The winner as the highest-yielding field of corn in United States last year was planted with a blend 
similar to this. Its the coming thing. We have tried and tested this blend on several farms under 
many conditions and in every ease, the yield of this blend was greater than when one strain of hybrid 
was planted alone. It stands to reason it would be. Illinois state college tests show, even in normal 
years when all corn pollenizes easily a scientific blend outyields one corn planted alone by 6 to 8 bu. 
per A. In a dry hot year, the difference would be twice this. 
As usual, I'm ahead of the pack. You’ll be hearing more about this from 
other companies when they learn about it from me. But DON’T JUST BUY 
ANYTHING THEY OFFER. It’s taken me years to work out this blend. 
It must be done just right.
