of the rocks concealed alons;- its southern foot or their positions."^ The 

 Korana hills, forty miles distant, afford the nearest evidence in this direc- 

 tion, and there the principal ridge, according to Dr. Flemingjf has a 

 uniclinal structure and northerly dip, like the Salt Range itself. 



The effort to recall a former state of things has been made by 

 Dr. Fleming J in treating of the upheaval of the range, and again 

 in an elaborate manner by Dr. Verchere § when writing of the larger 

 adjacent area. Dr. Fleming supposes three subsidences and elevations 

 to have taken place before the great elevation of the whole range ; 

 in the JMiocene period or subsequently, and contemporaneously with 

 that of the Himalaya. He also considers that the upheaval extended 

 from east to west. 



Dr. Verchere contends that the whole of the embayed ground 

 between the border ranges of North-West India was uplifted into an 

 open arch or dome-shaped anticlinal bordered by fissures, along one 

 of which, perpendicular to the others, the arcli was broken down, 

 leaving the Salt Range as its uptilted extremity. Botli of these 

 authors, Mr. Theobald,^ Mr. Medlicott,j| and Mr. H. F. Blanford^* 

 agree in attributing tlie elevation of the range to later tertiary times, — 



* No deep borings are known in the vicinity of tlie Salt Range : the wells for the piers 

 of the railway bridges oh the Jhelum and Chenab rivers are entirely in detrital deposits, 

 and these deposits only have been found in a boring at Anibala between the Indus and 

 Ganges basins. This boring has been put down to a depth of 700 feet, the altitude of the 

 locality being 919, so that the bore-hole has nearly reached sea level. — Professional Papers,
