1855.] HISLOP UMRET COAL. 559 



If we look beyond tliis province, we shall find this view amply 

 confirmed. The account given by Dr. Walker* of the discovery of 

 fragments of coal at Kota, in the Nizam's dominions, would lead to the 

 belief that the carbonaceous and bituminous shales which he noticed 

 were above the highest bed of argillaceous limestone. But whether 

 this may have been the case or not, is of little consequence ; as all I 

 contend for is, that they are near the base of the iron-banded sand- 

 stone, — a position which must at once be assigned them, when we 

 take into account their relation to the surrounding hills at Kotilf . The 

 succession at Duntimnapilly:|:, according to the same writer, seems 

 to have been — anthracite, carbonaceous sandstone, and micaceous 

 sandstone. What the rock, 15 feet thick, above the anthracite was, 

 he does not mention. But it is worthy of remark, that the carbo- 

 naceous, and micaceous sandstone into which the anthracite passes 

 downwards, bear a great resemblance to the strata underlying the 

 coal-seam at Barkoi, and appear to coincide with the 8 feet of lami- 

 nated sandstone mentioned by the late Dr. T. L. Bell in his detailed 

 description of the rocks bored through at Kota. It is to this la- 

 mented officer that we owe the best materials for comparing the coal- 

 measures on the banks of the Pranhita with those in the north of 

 Nagpur. The section with which he has furnished us is : sandstone 

 (iron-banded), from 50 to 500 feet ; argillaceous limestone 9 feet ; bitu- 

 minous shale three-quarters of an inch ; then argillaceous limestone, bi- 

 tuminous shale and limestone again, which passes into the laminated 

 sandstone alluded to above. Without quoting further from this list of 

 strata, which has already been published in the Journal § of the So- 

 ciety, I may mention that the bituminous shale at Kota, though to a 

 considerable extent interstratified with argillaceous limestone, &c., is 

 found only in the upper half, while argillaceous shales and limestone 

 preponderate in the lower half. Limestone, according to the most 

 recent information received from Dr. Bell, was the lowest rock 

 reached after passing through 27 feet of red clay-shale. 



Again, at Palamow, the first beds that IAy. HomfrayH came upon 

 under a mass of sandstone, 150 to 200 feet thick, were shale and 

 coal, resting upon 30 feet of sandstone, in which we may again trace 

 a similarity to the coal-field at Barkoi. Such also is the order of the 

 strata at Singra, as given by Mr. Homfray. Dr. Carter, in his 

 admirable 'Summary of the Geology of India ^,' shows that Jac- 

 quemont found small layers of anthracite between the strata of com- 

 pact limestone which immediately underlie the Panna sandstone. 

 According to Franklin**, in all the glens connected with the Panna 

 range, particularly in that of the Bagin River, black bituminous 

 shale crops out from beneath the sandstone. ]Mr. Osborne's obser-
