80 TALCHEEE COAL FIELD. 



These extracts seem to establish the existence of a boulder bed ia 

 Ramghur, about 200 miles due North from Talcheer, associated with 

 strata exactly resembling those of the lower (" Talcheer") beds of the 

 Orissa fields. 



But the homologies of the beds do not end here. A few sentences 

 after the above extract we read : — 



" The conglomerate developed near the village of Poonoo is nearly 

 " horizontal, but to the South of the village it dips to the E. of S. at angles 

 " varying from 8° to 14°, and before reaching the banks of the Damoodah 

 " River, the coal-bearing pudding-stones, sandstones and shales come 

 " in and extend along both margins of the above-named stream." 



Here it will be remarked that there is no mention of the " greenish- 

 grey shales and thin beds of fine-grained sandstone," said, with the 

 conglomerate, to attain a thickness of 900 to 1,000 feet in the Bohcahroh 

 Coal Field, and the inference that must be drawn is that they are absent 

 in the Ramghur field, as otherwise Mr. W. would in all probability 

 have mentioned them as another proof of the same deposit underlying 

 all the field. On the Upper Damoodah field therefore, as in Orissa, 

 it is probable that there is unconformahility between the representatives 

 of the Damoodah and Talcheer groups. 



From the evidence, then, which is thus presented, there can be little 

 doubt of the parallelism of the lower beds of Damoodah and Talcheer. 



When the organic remains of the middle group at Talcheer shall have 

 been examined carefully, and compared with those of the Damoodah or 

 Burdwan field, their identity will probably establish the relations of 

 these beds. As regards mineral character, it seems not at all impossible 

 that the bed marked 141 of Mr. Williams's Section {v. ante) of the 

 lowermost coal measures of that field, described as " white and light 

 "grey sandstone conglomerate, containing boulders of white quartz 12 

 " inches in diameter," with a thickness of 325 feet, may correspond to 

 the bed marked (c.) of the middle group of the Talcheer field.
