HOT SPlllNOS. 19 



The Aurunga is the only considerable tributary of the Koel within 

 our limits. It rises near Soheda in the pass descending from Lohar- 

 dugga into the valley, and pursues a winding course in a north-westerly 

 direction for a distance of about 50 miles. Where it traverses the coal 

 field it affords numerous and instructive sections. Leaving the coal field, 

 its bed rapidly widens, and by the time it reaches Palamow, where the 

 ruins of two considerable forts overlook it, it has attained a considerable 

 size, and, with its channel crowded with huge masses of gneiss, afi'ords 

 some very beautiful scenes. Owing to its rocky bed in this neighbour- 

 hood, its navigation would be dangerous during the rains. At other 

 seasons the supply of water is insufficient for even the smallest craft. 

 Its principal tributaries are the Sukri and Ghugree, both of which 

 traverse portions of the field. 



The Kunhur. — This river is in many respects similar to the Koel ; it is 

 about the same length, and pursues a nearly parallel course, to the Sone. 

 It is likewise, at least in its upper reaches, useless for purposes of navi- 

 gation. For a considerable portion of its course it constitutes a well- 

 defined boundary between Palamow and Sirguja. 



Section 4. — Hot Springs. 



In each of the separate areas described in this report, and in direct 

 connection with lin^s of fracture which it will be shewn have been in- 

 strumental in determining the present structure of the coal fields, there 

 are series of hot springs. 



The first of these is in close proximity to the Aurunga field ; it is 



situated in the bed of the Tataka River at Jarum,

about a mile and a half north-west of Pochra, or 



in north latitude 23° 49' and east longitude 84" 32'. Although the water 



actually finds its way to the surface through joints in some vertical beds 



of granitic gneiss, which are the only rocks exposed in that part of the bed 



of the river, the position is in immediate proximity to the continuation 



of the well-marked east-to-west fault which has cut ofi" the Barakars, &c., 



at the north-west corner of the Aurunga field. Were there a complete
