times loopwork is arranged in double or treble series, or there is a 
combination of these, as in j, k, and 71; m represents a style recently 
noticed on a basket made by a Spences Bridge woman. She declared 
that she had never made this kind before, nor had she seen it. She 
merely thought of it. Another woman who was interviewed said 
that it was not new to her, but that it was very little used.

Lids made of coiled work are a comparatively late development. 
Temporary lids for protecting the contents of baskets from dust, 
smoke, ashes, and insects have probably been in use for a long 
time. They consist merely of pieces of bark or board slightly larger 
than the mouth of the basket. Mats are even more frequently used, 
especially the small eating mats which among the Upper Thompson 
are woven of rushes, or elaeagnus bark; among the Lower Thompson, 
of cedar bark.
