I have examined the Belteram with what an untrained eye considers to 

 be considerable care. It is not all a case of south dip and north scarp, 

 the latter overhanging the plain. There was a regular range of long 

 narrow round topped hills ; the north slope of the anticline has gone in 

 some places, but in others its traces are visible, so that here and there 

 the dip of the Belteram nearest to the plain is to the north. Unfortunate- 

 ly at the points where the white sandstone comes visibly in contact with 

 the Belteram, the former is so powdered and broken and fragments of both 

 kinds seem so mixed that one can't see exactly what happens when the 

 two dips come into conflict. In places high masses of brecciated alluvivmi 

 cap the sandstone, as if washed down from the Belteram ridge by the 

 flow of a sea or river and deposited over the sea's white sandy bed. 



Beginning from the uprise of the Belteram at its west extremity, I find 

 the belt pretty wide here, dipping south and scarped north, with a 

 vanguard ridge of detached dark crimson hills some 200 yards in front of 

 its slope. This vanguard ridge dips deep south and evidently underruns 

 the main belteram beds. It too is of Belteram — but of a harder and coarser 

 material, with fewer fossils in evidence. The j)lain comes up to the foot of 

 the scai'p of the vanguard, and I can trace no sign of my supposed 

 anticline, though the debris on the plain extends some way. Perhaps this 

 anticlinal hill was broken clean in half by the fault. 



To the east of Wala Khawas Tank, the belteram shows a long elliptical 

 hill with a west dip of strata on its west flank, north dip on its north and 

 south dip on its south. All the centre has been eroded ; and the west and 

 Horth sides of the anticline have been eaten away and reduced much more 

 than the high south ridge. 



Beyond a nulla, I find another circular hill, dipping outwards on 

 all sides, also eroded in the centre. Then a long mound, probably the 

 relics of another round hill quite eroded, leads up to another circular hill, 

 whose strata dip outwards on all sides. A deep nulla defines its eastern 

 slope and a fovirth circular hill supervenes, its north side mostly vanished. 

 Then a long ridge, the south side of a quondam elliptical hill, for after 

 travelling along the ridge for 1,000 yards, I note a slight outcrop, 150 

 yards to the north, of belteram dipping north and gradually rising and 

 curving in to join my ridge, and beyond its junction the strata dips round 

 eastwards. Here it is that just to the north of the fault lies the broad 

 squat hill — 60 feet high — of white sandstone carrying its cap of belteram. 



But a peculiar sight to the south of this point is a great bowl 600 yards 

 across, its sides made of yellow belteram ridges. The bowl is like its 

 name, its ragged and jagged and jvitting edges rising some 20 or 50 feet 

 all round, all dipping outwards. Even the north side of it dips outwards, 

 its strata clashing with those of the main ridge which we have been follow- 

 ing. Evidently it was once a great cone of belteram — now all eroded — and
