above it ; below this is some ordinary dull coal with bright bands and 

 some shale at the bottom. The dip here has slightly altered, being 

 west-20°-south at 50 only. The thickness of the coal at the outcrop 

 is 11 feet. Further up the stream the dip of the Barakar sandstone 

 falls off to west-20°-south at 20°, whilst in the small stream to the 

 east it is south-west at 25 , and north of Ghogri south-20°-east at 15 . 

 It appears that there has been faulting here though no sign of it 

 could be found beyond the high dip except in the immediate vicinity 

 of the seam. It is probable that the vertical dislocation of the beds 

 is not great, and that the disturbance is caused by the continuation of 

 the Lodadeo-Rawandeo fault. It might be worth while, were borings 

 made in the field, to put down at least one here at some distance to 

 the dip, say, 200 yards from the outcrop, as it is possible that the high 

 dip is merely due to faulting, and at that distance the coal would have 

 resumed its normal dip. 



§ 15. — Summary. 

 These seven small fields exhaust what may be called the Chhindwara 



portion of the Satpura coalfields : as, with the 

 Seven fields. r r 



exception of the western portion of the Tawa field 



situated within the limits of the Betul district, the whole lie within the 



district of Chhindwara. The four areas of Dolari, Machna, Suki, and 



Sonada, have been fully described and mapped by Mr. H. B. Medli- 



cott. 1 These for convenience are grouped together as the Shahpur 



coal-fields being situated entirely within the district of Betul near 



the large village of Shahpur. I have nothing to add to Mr. Medli- 



cott's description, and in fact I have done little more in that part of 



the basin than fill in the main boundary where left incomplete by him 



and adding a few quartz veins and trap dykes, and the portion of the 



map on which the Shahpur fields are represented is almost entirely a 



reduction of Mr. Medlicott's large scale map of that area. 



The Barakar rocks consist of felspathic sandstones and shales not
