On Long Island, with salt marshes once all around it ("Drowned Meadow"
became Port Jefferson, NY) in the Suffolk County Museum are
waffle-like shoes one wore to harvest the "marsh grass" reportedly
used as insulation in wooden frame houses (aghhh!) until the practice
ceased. There is also today much "spartina patens" which according to
research by Envirosphere, Inc., are starting to appear in the Pacific
Northwest as an invading species.
