SEC. 2.] RUNN-ISLAND RANGE FROM PUTCHUM TO CHOEAR. 101 



Some of the silicious limestones of Putchum Peer hill have eherty 

 concretions, a few scattered quartz pebbles, and seem quite as unfossiliferous 

 as the limestones of Sitabund in the Dhar forest, Nerbudda valley, which 

 they somewhat resemble ; others are in places crowded with broken 

 fragments showing imperfect sections of univalves, &e. They are quite 

 the same as the strong orange calcareous beds of Raimulrow hill, east of 

 Kaora, which would doubtless form a good building stone, notwithstand- 

 ing their being deeply eroded by atmospheric action along joint planes. 



The view from the summit of Putchum Peer is most extensive, the 



Parkm- hills can be plainly seen with a waste of 

 Summit of hill. 



salt and water between them and the observer. 



The salt extended thence westward, and over it in a direction 30° 



north of west something dark was seen on the horizon, which may have 



been the 'Allah Bund.^ To the south and south-east salt was not 



observed, only the dark surface of the Bunnee and the Kutch hills 



beyond it. 



The southern or Gora Doongur (white hiU.) range is much less lofty 



than the other and has a much narrower base, 

 Gora DooDgur. 



Like that to the north its most precipitous side 



faces also northwards, and this feature coincides with a belt of contor- 

 tion in the rocks which terminates eastward in a bold anticlinal curve, 

 which, forming high ground, may be seen from long distances. 



AU along this range calcareous sandstones, coarse or fine grained, 

 with red fossiliferous layers, silicious and shaly olive beds, and hard 

 shelly bands, (the fossils being all fragmentary,) may be found. On the 

 crest of the hiU and southern flanks more brownish and purple tints occur, 

 and as the section ascends the beds become less calcareous, with highly 

 ferruginous layers here and there. 



Fossils are not numerous, but small eehinoid spines and broken 

 shells were observed in strong blue calcareous beds at the hills south
