On certain occasion a reporter asked a farmer if he could reveal the secret of his corn, which won the contest of the best product, year after year. The farmer confessed that it was due to the fact that he shared his seed with his neighbors.
”Why do you share your best corn seed with your neighbors, if you also enter to the same contest year after year?” asked the reporter.
”You will see, Sir,” said the farmer. “The wind carries the pollen of the ripe maize, from one crop to the other. If my neighbors cultivate an inferior quality corn, the crossed pollination would constantly degrade the quality of mine. If I am going to sow good corn I should help my neighbor to do it so too.”
