Sir William Dawson has divided caverns into those of driftage, 

 interment, and residence.* The Rock-shelters of Eastern Aus- 

 tralia are clearly a combination of the two latter, similar to some 

 of the European caves mentioned by him, such as the Dordogne 

 and Mentone Caves. "The accumulation of ashes, bones, and 

 other remains," says Dawson, " is in exact accordance with the 

 want of cleanliness of the ruder American tribes, and also with 

 the habits of a people who in summer live in the open air, or in 

 temporary cabins or wigwams, and only in the colder months or 

 in bad weather resort to more secure and permanent abodes."! 

 No doubt this equally describes the occupancy of our Rock- 

 shelters. 



The absence of bones of mammalia in the refuse heaps at the 

 mouths of the latter, other than those of recent species, is strong 

 confirmatory evidence of the non-existence of man together with 

 the extinct mammalian fauna of Australia.
