52 KING : COASTAL REGION OF THE GODAVARI DISTRICT. 



and contains fewer shells. Though less calcareous on the whole, it is 

 traversed by many veins of pure carbonate of lime, which do not occur 

 in the upper bed. 



(5). — A fine-grained green loam with an incipient concretionary structure, 

 containing a few threads of carbonate of lime, no shells. 



(c).— The last-named variety passes into this one ; the veins of lime become 

 larger, and highly crystalline, until the mass is a crystalline limestone, 

 with a few flakes and strings of the green earth, and these at last 

 disappear. The limestone is a faint yellow or drab colour, and very 

 coarsely crystalline. The facets of the crystals have the pearly lustre 

 of dolomite."

Such exceptional cases did not affect the general and more natural 

 condition of affairs in Central India ; but here on the eastern coast, it 

 has seemed necessary for me to state the apparent condition of the 

 intertrappean beds, which I feel sure Hislop, had he seen it, would have 

 seized on as helping to favour the far-fetched, though fascinating, expla- 

 nation which one is sometimes apt to take when considering the possible 

 action of intrusive trap sheets. I have gone over this Lower Goda- 

 vari outcrop of traps over and over again with Hislop's theory before 

 me; but the intrusion of 40 or 50 feet (at the lowest calculation) of 

 traps for a length of what must have been at least 14 or 15 miles 

 between the infratrappeans and an intertrappean band of 12 or 14 feet 

 thick was so inconceivable a phenomenon to me that I was ultimately 

 driven to hold by the simpler theory of a pouring out of the upper trap 

 over a estuarine deposit which had been simply laid down on a pre- 

 vious flow. 



This very small patch of traps and associated rocks is so isolated 



Relation of this out- ^ eie on ^ e e ^ s ^ ern coast from the well-known 

 burst to that of the immensely gieater development of traps in the 

 Deccan that it is difficult to conceive how they 

 can be connected either by previous continuity or by contemporaneity ; 

 for though their distance (200 miles) from the traps is small as compared 

 with the length or breadth of the Deccan area, still they are entirely 

 isolated without any connecting outlier between them and it. There is,
