Two fragments, one illustrated on Plate XXV, figure 8, are perforated, 
probably in order to bind the broken parts together after the pot was 
broken. 
A few fragments are encrusted on the inside surface with a black 
substance, evidently the carbonized remains of the food formerly cooked in 
them. 
Most of the fragments are light buff or light reddish brown. Others 
are dark grey. Some have the inside surface blackened. 
Some of the fragments are smooth, but not polished, and others are 
coarse and gritty to the touch. Both the inside and outside surfaces of 
many of the pots seem to have been coated with a thin layer of fine clay 
paste.

The material used in the manufacture of the pottery was clay without 
tempering, or a paste tempered either with crushed shell or small particles 
of quartz, feldspar, mica, and sand. Out of the total, seven hundred and 
forty-three fragments, two hundred and seventy-five, or 37 per cent, 
contained shell tempering, and two hundred and ninety-eight, or 40 per 
cent, stone tempering. The tempering material in the rest of the fragments, 
if there is any, cannot be determined. Angular depressions in some pieces, 
however, may have held pieces of shell, which decayed or became loosened 
and fell out (Plate XXV, figure 3, and Plate XXVI, figures 16, 17). None 
of the fragments has both shell and stone tempering. In many fragments 
(Plate XXV, figure 1) the shell tempering consists of large, angular pieces. 
One of the pieces in another fragment is as much as f inch long by £ inch 
wide. In only a few fragments is the shell very finely pulverized. The 
species of shell is not recognizable, although some pieces seem to be those 
of the soft-shelled clam. 
Most of the ware with shell tempering seems on the whole as firm as 
that tempered with stone. The fractured edges of a few pieces are much 
abraded and rounded, showing the softness of some of the ware. The 
pieces without any sign of tempering are hard and firm. Some pieces look 
almost as if they had been beach-worn. No pottery fragments were found 
on the slope of the exposed part of the shell-heap, which suggests that they 
disintegrated rapidly after exposure.
