CERAMIC TYPOLOGY


Bay Incised Casuela--caLiula-.haped vessels of Bay paste with in-
cising on the sides above the shoulders (P1. X, h).
Bay red-painted-sherds of Bay paste exhibiting red paint (P1. X,
k).
Bay Painted Plate-these are like those of the Botany Series except
for the paste.
Bay Unpainted Plate-like those of the Botany Series except for
the paste. Use of Bay paste gives them a red-painted appearance.

 Harbor Series

 Included in this series are vessels which may be properly re-
ferred to as shell-tempered. Shell particles are larger and much
more frequent than in the case of Bay paste while no grit is present.
Also present are fine grains of sand. The paste; thinness, Igulal it),
and surface finish of walls; and general appearance are all similar
to ceramics of the Coral Series (to be described next) Harbor paste
appears to Iepresent the addition of crushed shell, possibly on an
experimental basis, to Coral paste.
 Vessels are made by coiling, walls are 6-8 mm. thick, and surface
hardness about 2 on Hohs' scale. Color of surfaces I;rng' from
red to tan while that of cores may be tan or black.
Harbor Plain-vessels of Harbor paste which are undecorated. This
is the only type known for this series at present.
Harbor red-paintrd-one sherd of Harbor paste from the Francis
Bay site exhibits traces of red paint.

 Coral Series

 Vessels in this series differ sharply in paste, shape, and decoration
from all previously dIt- ribed except for Harbor Plain and some
Hull Plain examples. Paste of the Coral Series includes as temper
or as a natural inclusion in the clay extremely fine sand, usually
less than .25 mm. in diameter, although grains up to 1 mm. are not
uncommon. Larger grains are rare. The paste is well-mixed, very
compact, and vessels are well fired. Sherds of Coral paste "clatter"
with a reasonably high note when struck together while sherds of
the other series emit a "duller" sound when hit together.
