SEC. 6.] PORTION OF THE CENTRAL PLAIN NEAR BHOOJ. 165 



character^ and in some flaggy layers of the overlying sandstone near the 

 top of the clifi", a few fronds of Palaozamia were obtained. Others 

 occur in a bed of pale grey shale on this bank of the river at about 

 eight feet from the base of the cliff and nearly opposite to the place 

 where the double fault above mentioned is seen, the dip being still south 

 at 3° to 5°. 



In a similar shale bed at a short distance still further up the stream 

 are Palaozamice, Taxodites (?), Cuningliamites (?), Peco^feris, and a moss- 

 like plantj the Taxodites, having the carbonised black fronds strongly re- 

 lieved upon the bedding surfaces of the grey shale ; portions of the 

 leaflets possessing sufiicient pliancy to separate from the shale while 

 damp without breaking. (Plants in an almost identical state of preserva- 

 tion have been found in the Nerbudda valley in the Jabalpur series) . 



The principal coal seam of Trombow occurs on the right bank of 



the river directly opposite to the village, under- 

 Principal coal seam. 



neath a bed of red and yellow variegated sand- 

 stone fifteen feet thick, associated with some thin ferruginous layers 

 beneath and a band of grey shale through which an adit has heen opened, 

 apparently in connexion with an old shaft at a little distance from the 

 hank, and at the bottom of which water could be heard falling, while air, 

 sensibly warmer than the surrounding atmosphere, was felt to issue from 

 it. Below these shaly bands are white and purple sandstones with some 

 layers of the peculiar ferruginous concretionary rock mentioned and 

 figured at p. 115. Associated with these also are a couple of two-feet 

 bands of spongy-looking rough sandstone with obscure annelid (?) tubes. 

 Beneath these come the beds on the south side of the double fault 

 before mentioned, all the rocks exhibiting abundance of oblique lamina- 

 tion. 



Since this place was visited by Mr. Blanford, falls from the roof 

 of the adit have so blocked it up that the coal seam could not be reached,
