in turn, merges into the Age of Iron, but since these last two stages 

 belong to protohistorical and historical times, they are outside our 

 province. The Age of Stone did not come to an end throughout the 

 world at the same time. The natives of the New World, Australia, 

 and the islands of the Pacific were in the Neolithic Age, and those 

 of Tasmania in the Paleolithic Age, when discovered by Europeans ; 

 and some isolated tribes are to-day still using stone implements.

Man in North America. — No conclusive proof of the presence of 

 man in North America during the Pleistocene has yet been offered. 

 Indeed, it is doubtful if Paleolithic man ever lived on this continent. 



Earlier investigators were led to assign a greater antiquity to many 

 human relics than subsequent study has shown to be possible. Such 

 errors were the result of over-enthusiasm and a failure to take into 

 consideration all of the elements of the problem, some of which are

 such a conclusion lies in the fact that, in the shaping of a stone
