very slightly twisted.

The remarkable sample of matting shown in Fig. 99 is from a small piece
of pottery from Alabama. It has been worked in the diagonal style, but
is somewhat different from the last example. It has probably been made
of rushes or heavy blades of grass.

The texture shown in Fig. 100 is from a rather indistinct impression
upon a small fragment of pottery from Iowa. One series of the strands
seems to have been quite rigid, while the other has been pliable, and
appear in the impression only where they have crossed the rigid series.
The dotted lines indicate their probable course on the under side of the
cross threads.

This form of fabric is very common in modern work.


FIFTH GROUP.

In Fig. 101 I present a variety of ancient fabric which has not to my
knowledge been found upon ceramic products. This specimen shows the
method of plaiting sandals practiced by the ancient inhabitants of
Kentucky. Numbers of these very interesting relics have been obtained
from the great caves of that State. They are beautifully woven, and well
shaped to the foot.
