Vol. 65.] DEPTH AND SUCCESSION OF THE BOYEY DEPOSITS. 165 



the Basin, he himself was disposed to think that the gravel and 

 sand, shown at the base of the deposits, did not continue under- 

 ground (and, as the Author said, there was no direct evidence of 

 this gravel underlying the clayey beds anywhere) ; but this was of 

 no consequence in regard to the question of bow the beds lay in the 

 Basin. It seemed to him that there was no difficulty in the view 

 that the beds rose up gradually to the level of the Haldon Hills : 

 this needed no great angle of rise, and such rises occurred in other 

 well-known tectonic basins. 



Postscript to the Discussion. 



[In further reply to Mr. Howe, the Author has communicated 

 the following remarks : — ' The diagrammatic section exhibited at 

 the meeting and referred to by Mr. Howe was found to be an 

 incorrect copy of the Author's original drawing, and was so 

 coloured as to convey an erroneous idea of the succession. With 

 regard to the existence of other gravels overlying the Bovcy 

 deposits, besides those which appear to pass beneath them, it 

 is evident that Mr. Howe had not realized that this was fully 

 admitted in the paper. The basal beds exposed near Staple Hill, 

 on the south-west side of the basin, are not gravels but sands, 

 which at the very base contain flints, stones, and blocks of chert 

 like those on Haldon. There is also much sand as well as gravel 

 on the eastern border above the level of the plain. The superficial 

 deposits on the plain itself are mostly of a different character : 

 some of these may be of Pliocene and some of Pleistocene age. 

 The Author regards the area south of Newton as a separate 

 subsidiary basin, as explained in his paper on the " Origin of 

 the Plateaus around Torquay " Q.uart. Journ. Geol. Soc. vol. lxiii 

 (1907) p. 115.'— February 8th, 1909.']
