he slipping of one of the woof threads is well shown
in the upper part of the figure.

The fabric shown in Fig. 77 has been impressed upon an earthen vessel
from Macon, Ga. It has been very well and neatly formed, and all the
details of fiber, twist, and combination can be made out.

The example given in Fig. 78 differs from the preceding in the spacing
and pairing of the warp cords. It was obtained from a fragment of
ancient pottery recently collected at Reel Foot Lake, Tennessee.

Fig. 79 represents another interesting specimen from the pottery of the
same locality. The border is woven somewhat differently from the body of
the fabric, two threads of the woof being included in each loop of the
warp.

Fig. 80 is from the pottery of the same locality. The threads are much
more closely woven than those already given.

The next example, Fig. 81, impressed upon a fragment of clay from
Arkansas, has been made of coarse, well-twisted cords. An ornamental
border has been produced by looping the cords of the woof, which seem
to have been five in number, each one passing over four others before
recrossing the warp.

In no locality are so many fine impressions of textiles upon clay
vessels found as in the ancient salt-making districts of the Mississippi
Valley. The huge bowl or tub-like vessels used by the primitive
salt-makers have very generally been modeled in coarse nets, or
otherwise have had many varieties of netting impressed upon them for
ornament.

In the accompanying plate (XXXIX) two fine examples of these impressions
are given. They are somewhat more clearly defined than the majority of
those from which the other illustrations are made.

Fig. 82 illustrates a specimen in which every detail is perfectly
preserved. Only a small portion of the original is shown in the cut. The
cords are heavy and well twisted, but the spacing is somewhat irregular.
I observe one interesting fact in regard to this impression. The fabric
has apparently been applied to the inverted vessel, as the loose cords
of the woof which run parallel with the rim droop or hang in festoons
between the cords of the warp as shown in the il
