Common flax (_Linum usitatissimum_, L.) is another example of
introduced fibers used by the Indians in post-Columbian times. The
fiber was probably secured in trade. It was found in five specimens
made by the Winnebago, Potawatomi, Michigan, Ottawa, and Delaware
Indians. In the Milwaukee Public Museum is a bag (14619), made by the
Winnebago and composed entirely of flax cords. In a Delaware burden
strap (50-7191) in this Museum the fine cords are linen, but the
coarse cords are milkweed, _Asclepias syriaca_. In the Archaeological
Museum of McGill University is a wampum belt (M5932), the beads of
which are strung on a commercial linen thread.
