392 Geological Section of the Nerbudda [Aug. 



from Dobgur west to the Kanjee Ghatee, east, by five from the Pugara 

 Ghatee to the cave at Mahadeo. There being no underwood or low 

 jungle, this plain has much the appearance of a park ; two or three streams 

 wind through it in different directions. 



The whole of these hills are almost entirely one rock, a sandstone 

 (Dok 2) varying a little in color. I visited the top of one of the peaks, 

 Dokgur* by name, the same which is stated by Captain Franklin 

 to be 4800 feet high. On the pinnacle of this hill the pebbles 

 were lying, evidently detached from the sandstone by the action of 

 weather. These pebbles are to be seen in horizontal strata in many 

 places, where the bare mural rock rises 300 or 400 feet from the 

 plain. The only exception to this sandstone was, Dok 1, forming a 

 water-course about 200 feet below the summit, and which is crossed 

 once or twice in ascending to this peak, and Dok 3, about 150 feet 

 from the summit. 



In a cave, through which passed a stream, called Jumbo Dweep, the 

 specimen of silicified tree was found by Captain Ouselev, the descrip- 

 tion of which I give you in his own words. 



" After having swam in as you know some 40 or 50 yards, with 

 torches, where several passages appear to branch off, and not liking to go 

 farther in water, the depth of which was great but unknown, I came 

 back to the debris on which you stood, formed of broken masses from 

 above, under which the stream runs. On descending with the stream 

 by torch light about 20 feet through the sandstone excavated by the 

 action of water, we came to a small room 10 feet square by 10 or 12 high, 

 the stream falling by a crevice through the floor, about two feet wide. We 

 descended about 15 or 20 feet more, and between the sides of the crevices 

 was jammed the tree, a trunk with apparently stumps above, part of the 

 bark, all fallen forward and caught in a hollow of the sandstone made 

 by water : about 4 feet long by 18 inches wide, from 2 to 6 inches thick: 

 of this I struck off the piecef I gave you, and have brought away the whole 

 fragment, but not the tree, for what appeared was fully four feet wide, but 

 how large it may be I did not carefully observe." 



Lieutenant Finnis, in the Journal for February last, p. 79, appears 

 to me to give a greater degree of extent to these hills, than my observation 

 warrants. More than three sides of them are denned by the Deinwa, 

 taking its rise between the peaks of Bhimgur and Dokgur, and to the 

 westward of Dokgur a deep chasm immediately commences. Whether 

 the geological formation differs on the side towards the Tek, I have no 



* There are two other peaks exceeding this in height, viz. Putta Suukur, (above 

 the cave of Mahadeo,) and Choura Deo, the highest of all which I conjecture to be 

 about 5000 feet above the sea.
