Sir Robert Ball, in writing of the Ice Age, summarises 

 his reasoning thus: "We have a picture of a series of 

 clusters of ice ages and genial ages, each cluster being fol- 

 lowed by the next, after hundreds of thousands of years." 



We possess this picture in Stockport, at Portwood. 

 We have these geological changes — these clusters, in situ, 

 exposed to view, and open to examination.
