Bands of gypsum in V atc ^ an(i to tae eastward the sections again differ 

 the lower nummulitics. from those above described ; one or more thick 



bands of gypsum occurring in the basal part of the nummulitic series ; 

 and a 20-foot bed of this gypsum being seen to thin away to nothing 

 within a short space in the scarped out crop along the northern side of 

 the patch itself.

 gypsum layers are seen interposed between limestones and red clay, 

 and sandstones of a purplish colour occur also among the lower layers of 

 the nummulitic series. 



The faulting and disturbance of this part of the range are as pro- 

 minent as usual. The hi^h summit of Soortung
