Fascinating notes, Norm ... and we'd all love to see and read more, especially on the history of pearls in the U.S. My own father told a tale of finding "clams" in Pennsylvania streams as a young child, along with his brothers. There were 4 brothers, and my dad would have been less than 5 years old at the time, making this 80 + years ago. He and his brothers were saving tiny pearls in a jar till they had enough to make a necklace for their mother, from these "clams". Sadly, she died before my father turned 6, and in the turmoil of a household of a father and 4 boys, the pearls disappeared long ago.
