Dip, south- 20 °-east at 80° : coal hard. The limestone thins out within 

 a couple of yards, being in fact only an elongated nodule. 



Fifty yards higher are brown and carbonaceous shales with some 

 thin and crushed layers of coal. Then a 5-feet bed of hard coal dipping 

 east-30°-south at 60°. This seam appears to be the same as the last, and 

 also, perhaps, as the 6-feet seam in the Chota Taukak. 



It appears most probable that it was in this part of the SafPrai that 

 Mr. Bruce observed several beds of coal.* Two of them are stated to 

 have been 12 cubits (18 feet) and 25 cubits (37 feet 6 inches) thick, 

 respectively. Nothing of the kind is visible now, but in alluvial ground 

 the river-bed may have shifted considerably in fifty years, and from Mr. 

 Bruce^s account, with the illustration he gives,t there seems no reason 

 to doubt the accuracy of his observation. In the figure they are re- 

 presented as dipping east-30°-south at 60,° one being 100 or 150 feet 

 stratigraphically above the other. The coal is described as superficially 

 inferior to that quarried higher up the river.

visible. It was, however, in this neighbourhood, apparently, that Mr. 

 Bruce quarried his coal in 1828. On Thornton^s map of the Sibs^gar 

 district, the survey for which was made in 1839-42, there is '' Suffry 

 coal mine " marked on the left bank of the stream here, and although

 may have been repetitions of the same beds,
