It has rather been a problem whence the Tasmanian 

 Aborigines obtained the material for their implements. 

 The discovery of certain localities where the rock suit- 

 able for implements occurred in situ, and which were 

 unquestionably worked by the Aborigines, has partly 

 solved the problem. It is unquestionable that the 

 Aborigines obtained a certain amount of the raw 

 material from these so-called quarries, but it is equally 

 certain that a large portion was obtained from different 

 sources. 



One of the best-known " native quarries " is that 

 situated on Coal Hill, near Melton-Mowbray. A careful 

 statistic of the specimens collected by me around 

 Melton-Mowbray gave the following results : — 



Cherts of all kinds . 80.7 per cent. 



Chert from the quarry .... 6.1 „ 



Porcellanites 7.3 ,, 



Breccia 0.7 „ 



Others not included under 



the above headings 5.1 „ 



The above figures conclusively prove that, though 

 the quarry on Coal Hill was conveniently situated and 

 easily reached from the camping grounds near the 

 river, only 6.1 per cent, of the implements found were 

 derived from it. Far the larger portion, that is to say 

 93.9 per cent, of the implements, were made from rocks 

 which came from other places besides the quarry on 

 Coal Hill. A priori one would assume that, with such 

 a convenient place as the quarry on Coal Hill close at 

 hand, the overwhelming majority of the implements 

 would be manufactured from material obtained from
