On a reputed Coal Formation [no. 4, new series, 
along the eastern or Nagpore 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 either 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 ine 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 possible 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^ ha^d reached 111 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.
