conglomeriticj nodular and compact, resembling that seen near Bag-h, and 



containing greenish chert. Limestone occurs near the base. Near the 



top of the sandstone, which is about 50 feet thick, other bands of limestone 



of a different character occur, containing Bryozoa and other fossils. These 



thin bands represent the coralline limestone, so highly developed a few 



miles to the east. 



Another small patch of cretaceous rocks, SOO or 300 yards in length, 



was met with south-west of Dairee, and doubtless many similar small 



remnants occur scattered over the country. But along the greater part 



of this boundary, the trap rests immediately upon the crystalline rocks. 



About Tanda the Malwa scarp commences to lose its persistent 



Termination of Malwa character. The metamorphic rocks run further 



®^^'"P' and further to the north up every successive valley 



to the westward. 



Between Tanda and Bagh, very little of the cretaceous beds is seen 

 until the neighbourhood of the latter place, when they come in in con- 

 siderable force. Hence to the westward they occupy a large area. 



The boundaries are irregular as usual. Although the cretaceous 



beds increase in thickness to the south, they are

thin band, cut through in the deeper valleys, while 

 patches of trap rest everywhere irregularly upon them. 



Conglomerates prevail near Bagh, especially to the north of the 

 town, and the pebbles from them are spread over the country. On 

 some hills north of Agur, the sole beds seen between the trap and the 

 Bijawurs are these conglomerates, which are about 60 to 80 feet thick. 

 The coralline limestone disappears as a distinct bed, and although a 

 limestone with fossils, occasionally including Bryozoa, is met with west of 

 Bagh, it is no longer such a mass of comminuted corallines as to the east. 

 The very low southerly dip which is prevalent in the cretaceous beds 

 may have originally existed, and may mark increasing depth of water to 

 the southward, where the beds are thicker. But this is very doubtful.
