crop ; one 250 yards to the east of this point, at Datla, half-way be- 

 tween the two outcrops ; one to the east of this point at Panara, on 

 the left bank of the river to the north of the outcrop. 



In addition to these, it would be worth while to explore the Tamia 

 seam by driving a short gallery on the coal, and the Patakhera Sarni 

 seam by means of a boring to the dip. If the coal obtained in these 

 borings were analysed, the results would give a far better idea of the 

 quality of the coal than anything obtainable at the outcrop, and it 

 would be seen whether the coal continued in force to the deep. The 

 most favourable localities are Datla, Barkoi, and Chinda-Dighawani, 

 but the others should not be neglected. 



§ 23. — Iron Ores. 



There is an absence of good iron ores in this field. The ferrugin- 

 ous shales, mentioned by Mr. Blanford at Sirgora, gave on analysis 

 47 per cent, of iron. 



In the metamorphics, near Enkawari, the schists are somewhat 

 ferruginous, but the iron does not extend for any distance. 



§ 24. — Limestone. 



In the metamorphic rocks between Bakur and Enkawari, and close 



Crystalline limestone to the boundary, there are several patches of 



in metamorphics. crystalline limestone, which has been partially 



dissolved by the water of the streams passing over it, and redeposit- 



ed further down in the form of travertine or 

 Tufaceous deposits. 



tufa, turther to the east, where the streams 



fall a considerable height in passing from the metamorphics to the 



Talchirs, the tufa forms great blocks, filling up the bed of the streams 



at the bases of the waterfalls. 



There is a large amount of limestone in the form of nodules in the 



Moturs, from which, by careful selection, a fair 

 Motur nodules. 



lime could probably be made. Kunkur also 



occurs in portions of the area.
