This moose or leatherwood fiber (_Dirca palustris_, L.) was
encountered eleven times in as widely separated states as Arkansas and
Wisconsin. It was used both in the raw state, as strips twisted into
cord, and as treated fiber in finer cords and threads. A prehistoric
mat made by the inhabitants of Bushwick Cave, Arkansas, is composed of
this material (MAIHF 19-4635). Cloth of the Adena culture made, in
part, from this bast fiber (1200) is in the Ohio State Historical and
Archaeological Museum. In the Milwaukee Public Museum is a Wisconsin
Potawatomi bag (23447) in which the weft is nicely prepared fiber
from this plant. In the collections of this Museum is a Winnebago bag
(50-784D) woven with two kinds of cord; light colored cord of _Dirca
palustris_ and dark colored cord of _Tilia americana_.
