and implements, etc., to the graves in our own church- 

 yards and the machinery of our own times. This all be- 

 longs to history. Thus we trace geology into archaeology, 

 and archaeology into history. 



Primeval Man in America. 



It must be remembered that the different men we have 

 described in Europe represent different stages of progress 

 there. The progress has not been at the same rate every- 

 where, and therefore the different stages are not necessa- 

 rily contemporaneous. When America was discovered, 

 the native tribes were still in the stone age, and many 

 savages are only in this stage of advance now. The 

 advance was more rapid in Europe, apparently because 

 of the frequent and extensive migrations and conflict of 

 races there. Nevertheless, the rudest state (Paleolithic 

 age) Seems to have been nearly contemporaneous in 

 America and Europe, and probably elsewhere. 



Quaternary River-Drift Man in America. There 

 are many examples of rude flint-flakes in the river-gravels 

 of California and in the glacial drift of New Jersey and 

 Ohio. These were, it is believed, the work of a race cor-
