KHASI HILLS. 145 



A fault, or rather a group of two or three small faults, cuts this ridge 

 and has upthrown the coal, limestone, &c., on the 

 West about forty feet. This fault heads North 

 35° East or nearly North-East. It is rudely parallel with the face of 

 the ridge on the West, which has itself in all probability been the re- 

 sult of the degrading forces having acted upon or against a line of divi- 

 sion in the mass of the rocks. The main joints in the limestone have 

 also the same direction. 



Coal occurs at Lakadong in the Jynteah hills.

and has been worked to some extent. 



The village (Lakadong) is situated on a small elevated plateau or level 

 space, surrounded on all sides by crooms or valleys, some of which 

 are deep. In the centre of this level space rises an irregular wooded 

 hillock, chiefly composed of thick -bedded limestone, which crops out 

 boldly on its sides. (Plate IX.) 



By the road or path, Lakadong is distant from Burr-ghat on the 

 Hurry river about 7 to 74 miles, and is at an

elevation of about 2,350 feet above the level of 

 the sea, or about 1,800 feet lower than Cherra. At Burr-ghat the road 

 meets the river, and here the coal can be transferred to boats. 



Eound the small plateau of Lakadong, the coal is seen in several 



places, appearing in the face of the crooms, as

well as m a tew small pit-like hollows m the mid- 

 dle of the level ground. The whole area included in this plateau does 

 not amount to one square mile. Under the greater portion of this 

 space a bed of coal appears to spread, though very irregularly deve- 

 loped, and of this only a very small portion has hitherto been extracted. 



Close to the village itself (at a on plan) the coal is exposed in a 

 small water-course. It is here about five feet thick, dipping at a small 

 angle (4° to 6°) towards North by East with a sandstone roof and floor. 

 The roof is of sharp gritty texture, ferruginous, quartzose, and hard ;
