SMITHSONIAN FOLK LIFE MAGAZINE : UNDERGROUND RAILROAD QUILT CODES
Did slaves and Underground Railroad participants set out quilts that were maps to freedom, signals that it was a good time to leave, or that a particular house was a safe house on the way to Ohio Territory?
Patterns:
Bow Tie - Dress in disguise to appear of higher status.
Bear Paw - Follow an animal trail through the mountains to find water and food.
Log Cabin - Seek shelter now, the people here are safe to speak with.
Drunkards Path - Zig Zag as you go along incase you are being stalked by houndes.
Double Wedding Ring - It's now safe to remove chains and shackles.
*** This article suggests that the book about the codes, a popular book that I read years ago, is controversial...
Well, I believe it. I loved this book!
