and consequently to have remained 

 as an isolated mass or butte 

 standing out above the general 

 level of the surrounding plain (see 

 fig. 6, p. 120). 



Thus it seems probable that the 

 older ridge of Permian time was 

 reduced to a smaller ridge in 

 Eocene time, and that this latter 

 was again buried under the exten- 

 sion of the Bovey and Ailer-Vale 

 Eocene deposits. Finally, when 

 these Eocene beds were raised into 

 land and gradually removed from 

 the Torquay area by the pro- 

 longed action of subaerial agencies 

 throughout the Oligocene, Mio- 

 cene, and Pliocene Periods, the 

 twice-buried portion of the ancient 

 ridge was again exposed, and the 

 three existing hills have been 

 slowly carved out of it by the 

 excavation of the intervening 

 valleys. As already mentioned, 

 one of these valleys cuts com- 

 pletely through the ridge from 

 north to south, bearing testimony 

 to the remoteness of the time wehn 

 the watercourse was first estab- 

 lished. By this valley Kilmorie 

 Hill is completely separated from 

 the other two, which are much less 

 deeply divided from one another. 



The highest part of Kilmorie 

 Hill is only 353 feet above sea- 

 level, but Lincombe (or Oxlea) 

 Hill reaches to 400 feet, and 

 Warberry Hill rises to nearly 

 450 feet, so that the summit of 

 the latter is all but 200 feet above 

 the adjoining parts of the plateau- 

 area, over which it commands a 

 fine view (see fig. 5). 



The Brixham Plateau. 



No explanation of the origin of 

 the plateaus near Torquay can be 

 considered satisfactory, which does 

 not also afford an explanation of 

 the similar plateau to be found 

 on the southern side of Torbay. 

 This I was able to visit last year,
