were removed, and which were of about equal size. The entire 

 circumference is very finely worked, but the chief feature is 

 the very cleverly manipulated point which may have been used 

 as a borer. It is of a uniform reddish colour, with a feeble 

 glaze. Loc, Macumba (pi. xiii., fig. 1). [Compare ix., fig. 43.] 



11. Ovately formed Scraper. Size, 3j in. x 2J in. Under- 

 side approximately flat with doubtful percussion bulb. Upper- 

 side shows the natural surface of stone, in a marginal band 

 half around the specimen, and the crown has been reduced by 

 flaking. Secondary chipping has been done all along the 

 edge, which is somewhat serrated, forming an oval tool that 

 was probably used as a scraper. Colour, reddish-brown, some- 

 what lighter on the chipped edge. Glaze, somewhat feeble. 

 Loc, Stuart Creek (pi. xiv., fig. 2). 



12. Adze, with cutting edge two inches. in width, forming 

 the widest part of the implement, which is three inches in 

 length. The material is very fine in the grain and is of the 

 porcellanite type. The under-side is fractured along two- 

 planes that are opposed to each other at an angle of about 10°. 

 The implement is thickest at the basal extremity, gradually 

 thinning towards the cutting edge. The upper-surface has- 

 been worked to produce this latter effect. The cutting edge is 

 rather roughly chipped and gives evidence of wear by use. 

 Colour, dark red. Patina well developed. Loc, Stuart 

 Creek (not figured). 



13. Hand Chopper. A large flat subtriangular stone,, 

 measuring 6 in. x 5i> : in. Appears to have been a thinnish and 

 flattish gibber that had been fractured from the parent rock 

 by natural causes. It is fine-grained and very siliceous. Upper 

 and under-faces show no attempt having been made at 

 trimming. It has been worked on one edge only, showing a, 

 cutting face 4| in. in length, and gives evidence of much wear. 

 Dark red on under-side, rather lighter on the upper; chipped 

 edge almost free of colour, but is more glazed than the rest 

 of the tool. It is a most uncouth and rude implement that 

 was probably used as a hand-chopper, as the thick part of the 

 implement is on the side opposed to the cutting edge and has 

 been rounded off to suit the hand, while the opposite end has 

 been worked to an obtuse point. Loc, Macumba (pi. xvii.). 



14. A fine example of a Hand Chopper. Size, 6h in. x 

 4J in. The stone is a typical example of Desert Sandstone 

 and has been a "gibber," which was evidently selected on 

 account of its suitable shape. The implement is roughly 

 triangular, and both upper- and lower-surfaces are in their 

 ,native form and are almost parallel to each other. The 

 cutting edge has been developed in a curved outline on the
