40 odd Years ago my dad got some seed corn from an old man from Denton county. The old man said when he married his father gave him a team of mules, 80 acres, and a 50lb bag of seed corn. This was in the 1920. He said the Dent corn was named Preacher Hill corn, had a very small cob and IIRC made 12 rows of corn per cob.
The first year we planted all the seed and kept it all for next years seed. After that Dad planted about 10 acres every year for several years. We ate some but most we ground into feed using a hammer mill. Every year we kept a few gallons of seeds to plant next year.
Dad had a stroke in 96, my brother and I planted corn a couple years then he moved and I gave up.
This fall while cleaning up the farm I found a gallon of seed corn in a sealed gallon glass jar.
Im going to plant some this spring in my back yard garden. If it sprouts i'll try to get fresh seed to re-establish this heirloom seed.
I always enjoyed the "bite" of field or dent corn.
