Examples of this kind of weaving may be obtained from the fictile
remains of nearly all the Atlantic States.

The specimen presented in Fig. 64 was obtained from a small fragment of
ancient pottery from the State of New York.

It is generally quite difficult to determine which set of threads is the
warp and which the woof. In most cases I have preferred to call the more
closely placed threads the woof, as they are readily beaten down by a
baton, whereas it would be difficult to manipulate the warp threads if
so closely placed. In the specimen illustrated, only the tightly woven
threads of the woof appear. The impression is not sufficiently distinct
to show the exact character of the thread, but there are indications
that it has been twisted. The regularity and prominence of the ridges
indicate a strong, tightly drawn warp.

Fig. 65 represents a form of this type of fabric very common in
impressions upon the pottery of the Middle Atlantic States. This
specimen was obtained from a small potsherd picked up near Washington,
D.C. The woof or cross-threads are small and uniform in thickness, and
pass alternately over and under the somewhat rigid fillets of the web.
The apparent rigidity of these fillets may result from the tightening
of the series when the fabric was applied to the plastic surface of the
vessel.
