The class C. A. I. a. 2, axes chipped on both sides, has also 

 two sub-classes ; a. those hafted, comprising the West Aust- 

 ralian examples, and y8. those not hafted. The subdivision C. 

 A. II., Rasps, includes implements which have a concave cutting 

 or scraping edge, used for scraping hafts of spears, waddies, etc., 

 and is not further divided. 



The subdivision C. A., III., knives, separates easily into two 

 sections, a. those hafted and b. those not hafted. The section 

 C. A., III., a. has two classes: 1. single flake, and 2. multiple flake. 

 The class C. A., III., a. 1., forms two sub-classe.s, a. chipped and 

 IB. flaked. These sub-classes comprise the hafted knives of 

 Central Australia. The class C. A., III., a. 2., multiple flake, 

 comprises those knives formed by the placing of a number of 

 small flakes in a setting of gum on a wooden haft ; and is not 

 further divided. 



The Section C. A., III., /'. knives not hafted, is subdivided into 

 two classes — 1. chipped, and 2 flaked. These classes comprise 

 the Tasmanian knives and many examples from the mainland. 



The subdivision C. A., IV., adzes comprises the very fine 

 examples from Central Australiii, and the smaller ones from 

 South Eastern Australia, which were generally hafted, and from 

 Tasmania, which were not. 



The subdivision C. A., V., scrapers includes a large number 

 of chipped-edged implements, which do not come under the 

 headings of axes or knives ; but which, in their limits, 

 approach both of those sub-divisions. Their use is undoubtedly 

 for scraping wooden implements, skins, etc. The sub-division C. 

 A., VI., spearheads, forms to sections a. single flake and b. multiple 

 flake. Tlie Section 0. A., VI., a. is subdivided into three classes 

 — 1. chipped, 2. flaked and 3. serrated. Classes 1. and 2. resemble 

 (me another ; but are sufliciently distinct to justify their 

 separation. Class 3. comprises the finest examples of Australian 

 chipping work and, in the form of glass spearheads, are well 

 known. 



Section C. A., VI, i>. multiple flake, resemble the class, 0. A., 

 Ill, a. 2. multiple flake knives ; but are set in 1, 2, 3 or 4 rows 

 on the spearhead. 



The subdivision C. A. VII., as already mentioned, is for 

 purposes of classification of collections only.
