Working in The Garden

A prisioner in jail received a letter from his wife:
"I have decided to plant some lettuce in the back garden. When is the best time to plant them?"
The prisioner, knowing that the prison guards read all the mail, replied in a letter:
"Dear Wife, whatever you do, DO NOT touch the back garden! That is where I hid all the gold."
A week or so later, he received another letter from his wife:
"You wouldn't believe what happened. Some men came with shovels to the house, and dug up the whole back garden."
The prisoner wrote another letter:
"Dear wife, NOW is the best time to plant the lettuce!"

First U.S. yeast preparation patent

In 1863, the first U.S. yeast preparation patent was issued to J.T. Alden of Cincinnati, Ohio (No. 40,451), for "an improvement in the preparation of yeast" which reduced concentrated yeast from a plastic or semi-fluid state to a dry granular form, a convenient way of preservation for future use. His process was to press the live yeast concentrate through a fine wire mesh to produce threads of the substance of about 1/8-inch square. When laid on drying racks, moisture rapidly evaporated because of the high surface area, leaving the dried yeast in a finely-divided state. The granular form avoided the grinding and crushing needed with using cake form dried yeast, which mechanically damaged the yeast cells, reducing the active yield.
