32 HUGHES : KURHURBAlil COAL FIELD. 



6. — Course indeterminate. This dyke occurs close to tlie coal mine at Buriadih, 

 and extends from the gneiss on the east, to the coal measures on the west. 



7. c?.— Course nearly south-east to north-west. It varies, however, along portions 



of its outcrop. This large dyke crosses the Suni river west of Chunjka, 

 cuts the thick seam below the confluence of the Purtdiha and Puth- 

 rodiha nullahs, and passes ahout 2 yards north of pit 33 at Kope. It 

 is visible west of the Komaljore nuddee, but does not appear to extend 

 much beyond Buniadih. 



8. m. — Course indeterminate. This is a small dyke which affects the coal south 



of Khundiha. 



9. d. — Komaljor nuddi dyke, which is 40 feet broad, in places has' an approxi- 



mately noi-tli-north-east com-se. It shows several times in the channel of 

 the river, and affects all the seams in the neighbourhood. It extends in 

 both directions beyond the boundaries of the field. 



10. — Fragments of trap are strewn over the ground at the bottom of Bhuddua 



hill, north of Agdoni. 

 11. — This dyke occurs in the bottom seam of coal at the Domahani Ghat. ' 



12. d. — Ramnuddi dyke. This is extremely well seen, and is of large size. 

 It is traceable from the Khakho river, to the west of Inman's shaft, and 

 from there, between the two 'tolehs' of Dhobidih, and into the 

 crystallines through the Talcbirs. 



13_ The lowest of the seams in the first bend of the Khakho below Sati 



Gbat is altered by trap. 



14. — Course nearly north-west and soutb-east. This dyke is north of Manuktand, 

 and is seen in the gneiss beyond the field. 



15. y. — A small dyke, witb a north-west strike, occurs near Kope. 

 VIII. — Economic Summahy. 



An analysis of the information which has been gathered tends, I 

 think, to prove that the capacity of this field, as a coal producing* locality, 

 depends upon the extent to which its lower seams are developed, and
