33. Alternating sandstones and shales 



34. Coal 



35. Shales and sandstones alternating 



36. Slightly concretionary carbo-arenaceous shales 



37. Sandstone 



38. Carbonaceous micaceo-arenaceous shales 



39. Concretionai-y carbo-argillaceous shales with ironstones ... 



40. Coal 

 This coal is not of superior quality, but it is better than that of the 



other seams in this river. A twist in strike occurs in the seam ; 

 a few beds under it are visible on the right bank of the stream. 



41. Grey argillaceous shale 



42. Coaly shale 



43. Sandstone 



44. Grey argillaceous shale 



45. Fine grained micaceo-siliceous sandstone 



A reverse dip takes place, so that a synclinal trough is formed. As 

 the river flows transverse to the axis of the trough, the beds which 

 occur on the north face of the synclinal are lower in the series than 

 the ones which we have been studying on the south face. This is a point 

 to remember when going over the ground. The beds enumerated in 

 the following section will illustrate the group, in succession downwards 

 to within a hundred feet or so of the highest strata in the Bhagalatta.
