Near the spot marked on the (1-inch) map as More Luck pass; the 

 variegated beds rest almost, if not immediately, on the Khirthar lime- 

 stone, the surface of which, near Bhagothoro, looks worn and irregular, 

 as if it had been exposed and slightly denuded before the deposition of 

 the variegated beds ; whilst the lower Nari rocks are cut away so as to 

 form ridges, upon and against which the newer variegated beds have 

 been deposited. 



The eastern side of the ridge north of Bhagothoro overhangs the 

 river Indus, and the railway has now been constructed along the face 

 of the cliff not far from the bank of the river. In some places the 

 surface of the limestone is broken up by enormous cracks of great 

 depth ; these are said to have been caused by earthquakes in late years. 1 

 Probably an argillaceous bed underlies the surface limestone at such 

 places. 



North-west of the town of Laki a hot-spring (temperature 103°Fahr.) 2 



1 Mr. Fedden learned, by enquiry amongst the hillmen, that the great fissures were 

 produced by an earthquake within the recollection of the oldest men, and apparently nearly 

 60 years ago, and he suggests that the earthquake of 1819 may have caused the dislocations. 



2 The temperature of this spring is stated in the Gazetteer to range from 102° to 124° 

 Fahr. This, if correct, is very remarkable. Mr. Fedden and I took the temperature at an 

 interval of more than a year, and found it to be 103° on both occasions.
