Harris’ Northern Grown Sweet Corn 
We are large producers of the best market varieties of 
sweet corn seed. For many years we have made a specialty 
of growing both open pollinated and hybrid sweet corn seed 
of the finest quality here in the North on our own and 
nearby farms. 
Combining scientific breeding and careful selection 
with the greatest care in growing, drying and cleaning, we 
produce seed corn of the highest standard of vitality and 
purity. 
Hybrid Sweet Corn 
The large number of hybrids now offered make it 
difficult for the grower to choose the best. Good hybrids 
can be produced only from carefully selected pure line 
parent stocks. In the growing of hybrid seed corn constant 
detasseling of the seed parent is absolutely necessary. 
Many seed fields of hybrid corn are detasseled only three 
or four times but we find that it is necessary to go carefully 
through each of our fields twelve to fifteen times. This is 
expensive work but it is the only way to grow first class 
hybrids. 
Hybrid sweet corn cannot be saved for seed the next 
year as it breaks down. 
Seneca “60”—The Earliest Hybrid 
(65 days ) 
This new corn is the earliest Hybrid in production we 
know and one of the earliest varieties grown. In our trials 
it has been ready in 65 days and we have seen it mature in 
sixty days. 
The stalks are 4 to feet tall, with golden ears 
about 6 inches long, eight rowed, and ripening a large part of the crop over a short period of 
time. We recommend this extra early hybrid highly. Not resistant to Stewart’s Disease. 
See prices on page 13. 
Northern Cross 
An Early and Tremendous Yielding Hybrid (73 days ) 
This new corn is without doubt the best hybrid of the Whipple’s Yellow type. 
It is a hybrid of great vigor, producing fine stands of strong sturdy plants which seem to grow 
by leaps and bounds and produce great crops of large even ears. There are usually two and often 
three good ears to a plant. It is truly a tremendous yielder of fine large ears and is well suited to 
fill the gap between the extra early and later kinds. 
These large ears are very uniform in size, fully eight inches long with 12-14 rows of bright 
yellow kernels and are very attractive in appearance and of exceptionally high quality. 
Matures a few days before Whipple’s Yellow and from 10 to 12 days earlier than Golden 
Cross Bantam. 
Northern Cross is a product of our own breeding here in the North, being a cross between two 
of our own pure line inbreds and can be produced only by us. It is an outstanding market variety 
and we urge our customers to make a planting this year. See prices on page 13. 
Caution: Northern Cross is not resistant to Stewart’s Disease (wilt). 
“The Northern Cross Sweet Corn which I sent for last year was everything that your catalogue claimed it to be. 1 hope 
you will be able to fill my order this year as I like it as well as any sweet corn I've ever had.” 
George Wattenbe, Clinton, N. Y. April 14, 1939.
