Australian Ahorigliud Stone Imj^lements. 195 



The division C. B., cutting implements with edge produced by 

 grinding or polishing, includes four subdivisions : — I. Axes ; II. 

 Wedges ; III. Knives or Scrapers, and IV. Blanks. The last class 

 axes, etc., in the rough, is .simply for collection classification. 



As before, the nomenclature, as nearly as possible, gives tiie 

 uses of these implements as compared with European tools. 



The subdivision C. B. I. axes, forms two sections : a. those 

 grooved for hafting, and /?. those not grooved for hafting. This 

 separation, though convenient, is not altogether satisfactory, as 

 the title "not grooved for hafting" may imply that these axes 

 were generally hafted. As a matter of fact, it may be agreed 

 that the majority were never used with a haft while tho.se hafted 

 were also frecjuently used in the hand without the haft. The 

 section C. B. I. a. is not further subdivided. The examples at 

 present available are not numerous; it will, however, probably 

 be found necessary to make further subdivisions here. 



The section C. B. I. i>. is divided into six classes: 1. oblona: 

 ovate; 2. ovate; 3. deltoid; 4. gad-shaped; 5. adze-shaped; and 

 6. cone-shaped. The classification is based generally on the 

 .shape of the bodies. Class C. B. I. If. 1. is divided into four sub- 

 classes, depending upon the nature of the cutting edge. 

 a. straight edge ; /3. circular edge ; y. parabolic cutting edge ; 

 and S. with the edge not in, but inclined to, the plane of the 

 major axis of the cross section of the body. Sub-class C. B. I. ^. 

 1. y. occurs frequently in the Goulburn Valley, Victoria, and C. 

 B. I. ^. 1. S. connnonly in the Western District of Victoria; they 

 appear to merit separate classification. The class C. B. 1. />. 1. 

 comprises over 80 per cent, of the examples known to the 

 writers and the sub-class (3., circular cutting edge, forms 90 per 

 cent of that class. 



Class C. B. I. /'. 2., ovate, is not the same as proposed by Mr. 

 Etheridge,^ jutlging from the examples figured. His class is 

 included by the writers in the "oblong-ovate" C. E. I. /?. 1. The 

 axes now included in the ovate class are distinctly ovate both in 

 plan and in cross section. They may possibly be referable to the 

 subdivision, wedges ; but the absence of grooves and flattened 

 butt end.s, and the excellence of the cutting edges place them 

 preferably in the subdivision " axes."
