86(5 On a reputed Coal Formation [no. 4, new series, 



and preserving the original texture of the wood, and still even flexi- 

 ble, whilst other portions are completely converted to a substance 

 having all the appearance of coal. The silicified nucleus is tra- 

 versed by veins of iron pyrites. Great numbers of these silicified 

 pieces of wood are met with, in every part of the bed of tne river. 



In the Tal river, a small tributary of the Godavery, running into 

 it near Lingala, I observed in my return journey, — the debris of a 

 slaty coal, not in isolated masses, but thickly scattered over the 

 river bed, it had been washed from its position in the banks or in 

 some of the nullahs of this river. 



It was unfortunate that this material did not come to my notice 

 earlier ; as it would have been very desirable to make some exami- 

 nation of the district, through which the Tal run9, the monsoon 

 rains hovever had commenced on my arrival there and rendered an 

 expedition into this unexplored district impracticable this season. 



Mr. Tuke in his survey of the Sebbery river mentions the fact 

 of a report that coal exists up that valley, as the Tal river runs into 

 the same line of country that report seems to be confirmed in proba- 

 bility by the finding of the material in the Tal. 



The line of fault, before alluded to, as observable along the whole 

 course of the river has a tolerably general direction to the N. E., 

 points of greatest disruption and alteration being observable at the 

 Buddrachellum, Enchampilly and Aheree Barriers ; — at these places 

 the beds are turned up on end, and contorted in every possible 

 manner,— at the intermediate places the whole masses of country 

 seems to have been upheaved, the beds preserving a tolerably ho- 

 rizontal position ; this feature is well observed in the hills south of 

 Dewulmuree, where the strata can be traced running in horizontal 

 lines from hill to hill, the intervening valleys having been formed 

 by the washing away of portions of these beds; — towards the lower 

 part of the river, at Kota and also at Albaka the beds have an in- 

 clination downwards from this line of fault, so that, in travelling 

 in a north easterly direction from the river, a recurrence of the series 

 described, or portion of it, may be expected to be again met with. I
