On a reputed Coal Formation [no. 4, nuw skriks, 



along the eastern or Nagporc side from Buddrachellum, has caused 

 them to be much disturbed in places, on this account it is very dif- 

 ficult to ascertain their general inclination cither in amount or di- 

 rection, and a large number of observations were requisite before 

 this could even be surmised. 



At Kota the beds of limestone dip at a very low angle and a very 

 small amount in thickness of the beds can be observed ; — resting im- 

 mediately upon them is alluvial soil, forming the river bank at 

 this place : for some distance both up and down the stream, the 

 nearest place where beds lying beneath those at Kota is to be seen 

 is at Annaveram, one mile distant,— here a whitish sandstone crops 

 out having also a N. E. dip ; by comparing the inclination of the 

 strata at Kota and the distance between these two places, —I found 

 the thickness of the intervening beds could not exceed much if at 

 all 200 feet,— -having started my boring, therefore, at Kota I deter- 

 mined to continue it there and examine as much as possihie of these 

 concealed strata, which I could nowhere, — either up or down the 

 river, examine sufficiently in detail at the surface. 



The boring was commenced on the 19th of March,— on the 6th 

 of May, it had reached 1 1 1 feet in depth and come upon a bed of red 

 sandstone ; this proved about 5 feet in thickness, and was succeeded 

 by blue clay, and sandstone alternately ; we continued the boring 

 until the 14th, when it had reached the depth of .145' 8" and was 

 in a white sandstone much resembling that I had seen cropping out 

 at Annaveram and which I concluded to be the same. 



The boring was through 30 feet of very hard limestone beds, 

 with partings of thin beds of shaly and fibrous limestone and clays, 

 after which a series of hard calcareous clays and marls, variegated 

 in color, or of decided blue or red, until the sandstone was reach- 

 ed ; no where did I perceive the slightest trace of Coal. 



*A section of the ground as shown by this boring is appended. 



Through the limestones and succeeding clays, our tools brought 

 up frequently traces of the fish remains mentioned below.
