BESIDE THE CROMLECH, aoi 



the historical point of view, are quite modern 

 in the geological or even the anthropological 

 estimate. They have been erected a long 

 way on the hither side of the glacial epoch. 

 There were men in Britain before the last ice 

 age, and they have left their memorials in 

 the rough chipped flint implements of the 

 drift and on the hardened floor of caves ; but 

 every trace of their presence has of course 

 been planed off the actual surface of the 

 country by the great sheets of ice which, 

 during the last glaciation, ground down the
