THE HINGLADEVI FIELD,

ng sandstone much infiltrated with silica. Barakar sandstones are 

 also exposed at intervals up the Ghogra till they are covered by the 

 red clays of the Motur group. The measures are much disturbed and 

 must have been faulted down here and subsequently protected from 

 denudation by the trap. This seam was discovered by Major Ash- 

 burner. Its position would be very favourable for working being 

 south of the hills and within 3 miles of the large village of Umreth 

 (Oomrait), and it is possible that if it extends under the trap for 

 some distance the coal is less disturbed further from the fault ; the 

 chances are, however, that it is cut off to the north by another fault or 

 by the continuation of the Pench fault. The area covered by Barakar 

 rocks is only about ^ of a square mile. 



§ 12. — The Hingladevi Field. 



The next area of Barakar rocks towards the west is the Hing- 

 ladevi field, so called from a small jungle shrine situated within its 

 limits, and close to one of the coal outcrops. The shrine appears to 

 be associated in some way with coal in the minds of the Gond villa- 

 gers, whose name for coal is Hinglaj. The area occupied by Barakar 

 rocks is 2*8 square miles. 



This field is on the western continuation of the Barkoi field, from 

 which it is separated by the rising ground of Moturs — which overlap the 

 Barakars here dipping 3 to north-east close to the boundary in the 

 Chanpat Ghogra, while further to the north-east by Ekleyra the dip is 

 north-westerly, north-east of Umbara — and by the trap which covers it to 

 the east. This trap follows along to the south, forming the south bound- 

 ary for some distance till the actual contact with theTalchirs is exposed, 

 to the east of Bahadree. TheTalchirs continue to form the boundary 

 to beyond the village of Jumkoonda, where they are brought into con- 

 tact with the Moturs by a fault. The entire north boundary is formed 

 by the Moturs, which seem to overlap the Barakars to some extent. 



XV. — The most eastwardly exposure of coal in this area is in 



The Hingladevi out- the Hingladevi or Gogra stream ; it was known 



crop. previous to Mr. Blanford's visit, and some excava-
