nor was it traceable in the cliff outside. To quote from his paper on the 

 geology of Kutch, the seam is 1 foot 4 inches thick, overlying blue clay 

 with carbonaceous markings, and immediately succeeded by a band of 

 carbonaceous shale a foot thick, the section being thus : — 



Coarse brownish and white sandstone, very falsely -bedded 



Ferruginous sandstone 



Coarse white false-bedded sandstone with carbonaceous streaks, 

 especially abundant towards the base ... 



Ferruginous parting 



Coarse white and yellowish sandstone, false-bedded and con- 

 taining carbonaceous streaks in places 



Carbonaceous shale, passing down into 



Coal 



Blue clay with carbonaceous markings. 



" The middle 8 inches of the coal is very inferior, being rather a 

 shale than coal ; only about 8 inches is really good ; this is bright and 

 firm coal." It will be seen from this that the coal seam here is differ- 

 ently situated from that to the north, which is probably on a lower 

 horizon. Besides the small trap or lava dyke already mentioned, there 

 are two other intrusions of the ordinary solid grey trap in the vicinity 

 forming small rugged hills at a short distance from the west bank of 

 the river. 



On that bank also subreeent concrete occm-s of a suflSciently 

 calcareous nature to be burned for lime. 



It is only easy to determine satisfactorily the thickness of the upper 



division of the Jurassic rocks in the plain to the

east of Bhooj owing to the lowness of their 



dip and the probability of the existence of numerous faults. Calculations 

 from data so affected are liable to error, but making allowances they 

 may have a depth of nearly 3,000 feet; while that of the beds belong- 

 ing to the lower group to the north may exceed this by a considerable 

 amount as already stated.
