A couple was making their firs...

A couple was making their first doctors visit prior to the birth of their first child. After the exam, the doctor took a small stamp and stamped the wife’s stomach with indelible ink. The man and his wife were curious about what the stamp was for, so when they got home, the man took out his magnifying glass to try to see what is was.

Gunpowder mill

In 1639, the first record of the establishment of a gunpowder mill in the American colonies was an order from the General Court of Massachusetts granting 500 acres of land at Pecoit, Mass.
