SOHAGPtJR COAL-FIELD. 53 



There is a sufficient workable thickness of coal, but an analysis of. it by 

 Mr. Mallet was disappointing.

Volatile, exclusive of moisture ...... 9 - 5 



Carbon, fixed 40 5

If it were not that the distance between Guraru and the Kunuk out- 

 fall was rather too far, and the evidence too imperfect to reduce correla- 

 tion to a certainty, I might be tempted to suggest that from the simi- 

 larity in the composition of the coal at these two places, the exposures in 

 both localities are of the same seam. 



With this notice is ended the description of all the more important 

 outcrops of coal in the actual bed of the Son and the area drained in the 

 lower courses of the lesser tributaries that join it below Antikpur, after 

 the commencement of its traverse through the Barakar group. 



A large number of specimens of plants were found with comparatively 



little trouble in the tracts of land enclosed by the 

 Fossils. y 



Son and the supra-Barakars, north of the latitude 



of Nabalpur. They were mainly of the genera Glossopteris, and Verte- 



braria, and the latter occur in profuse abundance in many spots. 



Quoting again from Dr. Feistmantel's Fossil-Flora of the Rewah Gond- 



wana basin, 1 the different forms determined, and some of the localities 



whence a large proportion of them were procured, are — 



Amliha, Glossopteris communis, Glossopteris angustifolia, Vertebraria 

 indica ; Maiki, Glossopteris communis, Vertebraria inclica ; Murna river, 

 Trizygia speciosa, Bicksonia hughesi, Glossopteris angustifolia, Gl. com- 

 munis ; Guraru, Vertebraria inclica, Schizoneura gondwanet/sis, Glossopteris 

 angustifolia, Gl. communis, Gl. formosa, Gl. formosa var. major, Gl. 

 indica, Gl. browniana, Squama gymnospermarum ; Sarsi, Schizoneura 

 gondwanensis, Glossopteris browniana. 



In this list Vertebraria is found high up in the series, and it is abund- 

 ant everywhere. Trizygia is seemingly confined to upper beds. Certain
