240 The Philippine Journal of Science 1921 
Plate 4, fig. 1, shows an earthenware vessel of a design with 
which the writer is quite unfamiliar in the Philippines. 
Plate 4, fig. 2, may be either the bottom part of a native stove 
or a fragment of a lid of a giant tinaja (water jar). 
In Plate 5, fig. 2, is shown a bracelet cut from the top of a 
large Conus shell, while the other two fragments (fig. 1) are 
pieces of pipe bowls. 
We come now to the most interesting of all the artifacts 
found in these caves, namely, the stone implements. So far 
as the writer knows there are only five of these known from 
the Philippines; Mr. Dean C. Worcester has two, the writer 
has one that was given him years ago by a prospector but 
about which he has no data, and the two that are pictured in 
Plate 5, figs. 3 and 4. The one shown in Plate 5, fig. 4, is made 
from a greenish colored felsite, probably a fine-grained diorite, 
and may have been used as a hide scraper. Professor Beyer has 
suggested to the writer that the implement was made from 
this rock because of its general resemblance to jade, from 
which material many Chinese implements were, and perhaps 
still are, manufactured. 
Plate 5, fig. 3, shows an implement of a cherty material, 
which was undoubtedly used as a sort of combination hatchet 
and chisel. These stone implements, some believe, may have 
some historical connection with the ancient Chinese mining 
exploits on this island. The writer is not in accord with that 
view, since tools of this design or of this material would be of 
little use or effectiveness in mining operations. He is of the 
opinion, on the other hand, that these stone implements represent 
a true indigenous stone-age culture in the Philippines belonging 
to the Neolithic Period. 
The writer disclaims any pretense to a special training in 
ethnology ; he has described these finds in the hope that 
qualified persons may become interested enough to make fur- 
ther investigations. However, the writer is sufficiently informed 
along those lines to realize the importance of a complete study 
of this subject, if any safe conclusion as to early movements 
of peoples in the Pacific area is to be arrived at. He agrees 
with a recent statement of Hrdlicka that the solution of Pacific 
anthropology and ethnology will have to be arrived at by way 
of a more complete study of the Continent of Asia and the 
festoons of islands off its east coast. The writer believes that 
the Philippines are in a strategic ethnologic position with re- 
spect to such a study.
