TESTS AT CORAL BAY


Plates XIII-XIV.
 Other artifacts from the site are a petaloid celt and two celts
 with ground polls, two hammerstones, two utilized flakes, some
 ochreous rock, and a "bead" (P1. XIII, d) made of green jadeite.
 This "bead" is flat on one side and convex on the other. The hole
 is drilled from the flat side where it is much larger than on the
 illustrated convex side. Oval in outline, edges of this specimen
 have been ground as if for inserting in a mounting like that of
 a signet ring.
 Among shell specimens are four fractured tips and a worn or
ground corner point of a Strombus gigas shell (P1. XIII, a). Such
specimens have been included by others as artifacts and de Jong
(1924) suggests they are prototypes of stone three-pointers. Hatt
(1924: P1. VIII) also pictures one from Coral Bay.
 Sherds from Coral Bay average small in size and in many cases
have rounded edges. Colonial or more recent items were found in
the first and second levels of all tests except Test B. This suggests
both trampling (aboroginal and recent) and disturbance either as
a result of Hatt's activities or from cultivation.
 In spite of this, it is believed there are some trends indicated by
the vertical distribution of pottery (Table 5). The percentage of
Coral as opposed to Botany Plain increases with depth. Decorated
sherds of Coral paste are more apt to be from lower zones. Pres-
ence of Botany Plain and of griddle sherds in the lowest zones
should be noted. As usual there are no significant variations in
griddle modes with depth. It should be pointed out, however, that
the only griddle fragment suggesting a legged griddle or one with
a basal supporting ring (P1. XV, h) came from the middle level of
Test A.
 There are many differences in the ceramics from the site at
Coral Bay and those from sites previously discussed. The greatest
difference, of course, is the presence in large quantities of sherds
of the Coral Series. A casual comparison of Plate XIII with any of
the preceding illustrations suffices to demonstrate this point. The
fineness of the sand temper, the excellent surface treatment, and
the graceful shapes (Fig. 3, top two outlines) have been included
earlier in the typological section.
 Sherds of Botany Plain at Coral Bay are different from those
