50 years ago, an old country doctor drove to town, hitched his horse, quietly slipped into a drug store by the back door, and began “dickering” with the young drug clerk.

His mission was destined to yield great wealth to many people. It was destined to bring to the South the most far-flung benefit since the Civil War.

For more than an hour, behind the prescription counter, the old doctor and the clerk talked in low tones. Then the doctor left. He went out to the buggy and brought back a large, old fashioned kettle, a big wooden paddle (used for stirring the contents of the kettle), and deposited them in the back of the store.
