122 RANIGANJ COAL FIELD. [CllAP. IY. § 4. 



Khyrbona, in the Besram, a little above its confluence with the Mokhura 



or Machkundona stream, a 3^-feet seam crops out, from which some 



coal has been extracted by a native. A little North of this is a saline 



spring, slightly warm, and at this spot, probably, the large fault already 



mentioned crosses. 



North-west of Marulia, a seam about 5 feet thick was formerly 



worked bv the Bengal Coal Company, and to the 

 Near Marulia. * * r J 



South of it, the out- crops of at least twelve other 



seams are seen in the Besram, none of them exceeding 3 or 4 feet in 



thickness. The section is imperfect, and thicker beds may occur, but 



it is a remarkable fact, that, throughout all this area, no seam is known 



to exceed 5 or 6 feet in thickness, and by far the larger number are 



below 3 feet. In the Machkundona, South of 

 In the Machkundona. _ . , 



Marulia, only four or nve seams are seen on the 



same strike as the more numerous beds in the Besram ; one has been a 



little worked, and has produced good coal, but the thickness is only 



2\ feet. It is evident that all the coal seams in this part of the field 



are exceedingly thin, 



From Marulia to Beharinath few beds are seen, sections being scarce 

 and imperfect when met with. Two thin seams of coal, and a thicker 

 bed of a mixture of coal and carbonaceous shale, are exposed in the 

 stream which runs between Hadhi and Nautundhi. 



In the Tinttiliarak stream, North of Chakbaga, only one seam is 



cut through, and this, like those already men-

tioned, is a thin bed, totally useless economically. 



This bed is close to the top of the Raniganj series, and rests on thick 



conglomerate beds, with grey muddy shales, the former unusual above 



the Lower Damudas. The beds dip to three sides, North, East, and 



South, from near Dumradhi, and North of Chakbaga a large fault 



crosses the stream. South of this, and close to the boundary of the 



field, four seams of coal are intersected by the stream. They dip at very
