UNCOMMON TYPE OE STONE IMPLEMENT. 
two are the only examples of this type of implement wfliich 
are known from New Guinea. According to Mr. E. W. P. 
Chinnery, Government Anthropologist, T.N.G., such implements 
are not made or used by the present natives. All three came 
from below ground level, and are almost certainly prehistoric.* 
Their similarity of outline strongly suggests relationship 
with the Australian implements, but with so few examples and 
with our present lack of knowledge of the archaeology of the 
two countries, the point cannot be stressed. It is significant, 
however, that similar implements appear to be an early type 
both in Australia and in New Guinea. 
8. From the Yodda Valley, Papua. Fig. 8, Plate IX. 
This implement was first described by C. A. W. Monckton, 
Resident Magistrate, British New Guinea Annual Report 
1903-4, Appendix D., p. 31. It has also been illustrated and 
described by C. G. Seligman, and T. A. Joyce, Anthropological 
Essays presented to E. B. Tylor, 1907, p. 327. 
Made from a single large flake of obsidian. The sides and 
butt are regularly and symmetrically shaped by secondary 
flaking, from both front and back. (Part of the butt is at 
present obscured by a modern hafting.) The degree of skill 
shown in the making of this implement is without parallel 
amongst chipped implements from New Guinea or the adjacent 
islands. The technique of working from both sides is not 
otherwise known from this area. As an axe the implement is 
unique also, in that the untrimmed edge of the flake has been 
utilized as the cutting edge. 
Found below the surface of the ground. 
Length, 7.2 inches. Maximum thickness, about 2 inches. 
In the collection of the London Missionary Society, Samarai, 
Papua. 
9. From left hank of N ami Creek at its junction with the Bulolo 
River, Territory of New Guinea. Fig. 9, Plates IX and XI. 
Hard, fine-grained micaceous schist. Weathered or worn 
so that the harder portions of the rock protrude as ridges. 
Traces of what is apparently hammer-dressing are visible but 
most of the original surface has disappeared.
