UNCOMMON TYPE OF STONE IMPLEMENT. 
Found in a sluice box in which auriferous wash was being 
treated. The wash came from a terrace gravel deposit which 
extended from 12 ft. to 45 ft. below the surface. Twelve feet 
of overburden had been removed. It is thus probable that the 
implement came from the gravel, at some depth between 12 to 
45 feet, but the possibility that it may have been accidentally 
included from the overburden cannot be ignored. 
Length, 6.75 inches. 
National Museum, No. 40372. 
10. From right hank of Nami Creek at its junction with Koranga 
Creek, Bulolo Goldfield, Morobe District, Territory of New 
Guinea ( about ^ mile above the position of No. g). 
Fig. 10, Plates IX and XI. 
Very fine grained dark green compact homogeneous rock, 
with the remains of an interbedded vein of calcite on one side. 
Abraded but not patinated. It is doubtful whether marks on 
the surface are those of hammer-dressing or not. 
Found in a sluice box under conditions similar to No. 9. 
Length, 6.25 inches.
