138 KIIASI HILLS. 



character, although, where the surface is a little weathered, the cause of 



this structure becomes evident. 



Near Lakadong. — I have already mentioned the mode of occurrence 



of the limestone at Lakadong; it is in every 

 Limestone at Lakadong. 



respect similar to that at Cherra Poonjee. At 



Lakadong, however, there are two distinct deposits : one occurring under 



the coal of that place, and being, I believe, the parallel of the limestone 



at Cherra : and the other, above the coal and overlying sandstones. 



Of the latter deposit, which at Lakadong attains a thickness of at least 



50 feet, there appears to be no representative at Cherra Poonjee. 



Again, precisely as at Cherra Poonjee great deposits of a num- 

 mulitic limestone are found at the base of the hills, so below Lakadong 

 there is a great extent of similar limestone. This is seen on the banks 

 of the Harry River, North of the village of Pichadar Poonjee. The beds 

 here dip at a high angle (5-5° to 65°) to the South, and support a great 

 thickness . of sandstones and shaly beds, which are all conformable to 

 the limestone heloyf.fa) To these deposits of limestone and their mode 

 of occurrence, I shall again refer. 



Reverting to the nummulitic limestones of Cherra, there are some very 



interesting appearances presented by the upper 



Ancient demulation of portion ^f the deposit. In the mass of the 



the limestones. ir J- 



upper beds (which, as I have mentioned, are 

 more earthy than the lower), there are imbedded several small patches 

 of coal and coaly mud. The upper surface of the limestone is also 

 very irregular ; and here and there filling up the hollows in this wavy 

 surface, and covered by the sandstone, are thin pieces of coal and coaly 

 shale. In one place the upper beds of the limestone have been removed 

 to the depth of some feet, in the form of a channel or gully, as if by 

 the action of a stream : and this gully has subsequently been filled in 



(a) Having merely seen these beds in passing up the stream, I cannot enter into any 

 details regarding them.
