me locality. The material used is a vegetable fiber
obtained from the bark of trees or from some fibrous weed. This specimen
is now in the National Museum.

An interesting variety of this form is given in Fig. 96. It is from a
small piece of pottery exhumed from a mound on Fain's Island, Jefferson
County, Tennessee. The threads of the woof are quite close together,
those of the web far apart.

A very fine example of this variety of fabric was obtained by Dr. Tarrow
from an ancient cemetery near Dos Pueblos, Cal. It is illustrated in
Fig. 2, Plate XIV, vol. VII, of Surveys West of the 100th Meridian.[4]
In describing it, Professor Putnam says that the fiber is probably
obtained from a species of _yucca_. He says that
"the woof is made of two strands, crossing the warp in such a manner
that the strands alternate in passing, over and under it, and at the
same time inclosing two alternate strands, of the latter, making a
letter X figure of the warp, united at the center of the X by the
double strands of the woof."
It should be noticed that the series of cords called the woof by
Professor Putnam are designated as warp in my own descriptions. The
illustration shows a fabric identical with that given in the upper
figure of Plate XXXIX, and the description quoted describes perfectly
the type of fabric under consideration.

[Footnote 4: Putnam, F. W., in Vol. VII of Surveys West of the
100th Meridian, page 244.]

This method of weaving is still practiced by some of the western tribes,
as may be seen by a visit to the national collection.

A somewhat complicated arrangement of the threads may be seen in
the fabric shown in Fig. 97. It is clearly only a variation of the
combination just described. The manner in which the threads pass over,
under, and across each other can be more easily understood by reference
to the figure than by any description. It comes from one of the
Northwest coast tribes.

FOURTH GROUP.

A fourth form of fabric, illustrated in Fig. 98, is of very rare
occurrence on our fictile remains.

[Illustration: Fig. 98.--Diagonal fabric, ancient pottery of
Tennessee.]

It is a very neatly woven diagonal from the ancient pottery of Polk
County, Tennessee. Two series of cords have been interwoven at right
angles to each other, but so arranged
