In addition to the writer's paper on the stone implements of Botel Tobago published ten years ago, Mr. E. R. LEACH has described these implements in a recent issue of "Man". In this paper, the writer describes certain materials added to his collection since the date of his last paper, particilar, their uses and their relations to those found in adjacent regions.
The author, after all has only a few examples of stone implemenst from Botel Tobago, all of which were either obtained from the Yami men who had them as heirlooms from their forefathers, or were found buried under ground when they were working in the fields. The Yami is one of the few tribes in southeastern Asia who have a legend that their forefathers have used stone implements in ancient times.
Fig. 1, a stone implement which they call Chichivchiv and which has a characteristic waist form of outline, is made by knocking a piece off a waterworn boulder, so numerous on the sea-shore, one of its facs being chipped until it is flat, but rough, while its other face is left unworked, being smooth and convex. According to the Yami, this tool was not hafted to a wooden handle, but was held in the hand by itself for striking at and removing the roots of grasses and shrubs, and also when loosening the earth of a field. At present the Yami use only a digging-stick in working in the field, the hoe complete with head and wooden handle being quite unknown to them. The Chichivchiv presents an interesting problem regarding the use of certain types of chipped stone implements, to which hitherto had generally been believed were used for hoeheads.
Figs. 3, 4 show a Roofed axe (Dachformige Beil), which the Yami men call Uma-no-inapo (chisel used by the ancester). Now the Yami men use an iron chisel that resembles in shape this stone implement.
Fig. 5 (left) shows the stone implement which the villagers of Irararai call Chichivchiv. It is a asymmetrical adze which J. G. Andersson named, a Fourcornered axe (Vierkantbeil), ground on one side only. It is said that it was hafted to a wooden handle in such a way that the blade shall be parallel to the handle, and used for removing the roots of grasses and shrubs. The principal wood-working tool of the Yami is an axe, or Wasai, no adze in any form being found. From the presence in Botel Tobago of plank-built boats that seem to have been in use from years back, and from the fact that the term Wasai means axe as well as iron both in the Philippines and in Indonesia, the author is inclined to believe that the axe iron head seems to have been in use from remote times.
The stone implements from Botel Tobago are made of six kinds of rock, namely andesite, basalt, porphyry, sandstone, quartzite, and nephrite. Although the first mentionedrock is in found Botel Tobago, the remaining two rocks are not, which fact seems to show that some of the stone implements were introduced to the island by immigrant tribes.
So far as our present knowledge goes, the stone implements of the northern coasts of Botel Tobago appear to differ somewhat from those of the southern coasts. Those found in the latter, namely, the Roofed axe (Dachformige Beil) Figs. 3, 4 and the Cylindrical axe (Walzenbeil) (Fig. 2) are closely allied to those of the Philippines, . while those of the northern coast, the Fourcornered axe (Vierkantbeil) made of silicified sandstone of bluish-grey colour (Fig. 5, left), and earrings of nephrite (Fig. 6.-2, 3) have been excavated from the Yuwao site of Samasana island, pointing to some sort of intercourse between Samasana island and the northern coast of Botel Tobago. This is also suggested by a legend of the Irararai village to the effct that the Shirarorarogan, a tribal group of that village, who had unique customs differing from those of other groups of that village is, said to have been engaged in considerable traffic on the seas between Botel Tobago and Samasana island, eleven generations ago.
