ME. A. J. JUKES-BKOWNE ON 



[May 1906, 



simple and natural explana- 

 tion of the distribution of 

 the Clay-with-Flints in this 

 area, which would be very 

 difficult to account for on 

 the supposition of its being 

 entirely or mainly a Chalk- 

 residue. Thus, round Han- 

 nington there are patches 

 which, if united, would lie 

 on a curved surface that 

 would partly wrap round 

 the eastern termination of 

 the Kingsclere pericline, and 

 this surface, if prolonged, 

 would meet the outcrop of 

 the Beading Beds near 

 Wolverton and Ewhurst. 



From the high ground 

 nearHannington the patches 

 of Clay-with-Flints descend 

 southward and south-east- 

 ward to a level of 370 feet, 

 and some of them are 

 traversed by the rail- 

 way-cuttings near Church 

 Oakley. From this low 

 level remnants of what was 

 once a continuous mantle 

 rise gradually again to over 

 600 feet, on the high ground 

 south of Basingstoke. I 

 take it that this descent of 

 the Clay-with-Flints coin- 

 cides with a synclinal flexure 

 of the Chalk between the 

 Kingsclere pericline and 

 the Bentley-Farnham up- 

 lift, which is little more 

 than a monocline. 1 



As for the large spreads 

 of Clay-with-Flints on the 

 high ground around Far- 

 leigh, Ellisfield, Herriard, 

 and Lasham, and thence 

 eastward along the summit-
