230 Report on the Geological Structure of the Salt Range. [No. 3. 



The map is I believe the first which has ever been made of the 

 Salt Eange from a regular survey, and for its accuracy Mr. Purdon 

 is alone responsible. I trust it will supply a want in all maps of 

 the Puujaub hitherto published, in none of which, that I have seen, 

 is even the general direction of the Eange correctly laid down. 



The geological examination of the Eange has been executed 

 entirely by myself, and in addition to that of the Salt Eange proper, 

 a rapid survey was made of its continuation in the range of hills 

 which runs down the west bank of the Indus from Kalibag to Kaffin 

 Kote. I thus have been able to add considerably to our previous 

 knowledge of the geology of the Punjaub. A most interesting mass 

 of hills called Kovana, which rise abruptly from the plain of the 

 Jetch Doab, has also been examined. 



During the course of my labours I executed a rough military 

 survey, with a hand prismatic compass, of the district passed over, 

 from which I constructed for my own guidance a rough sketch map. 

 This I have had copied and coloured geologically, by a Mr. Blaney, an 

 Eurasian draftsman, and herewith submit it as illustrative of my report. 



The report itself will be found in many parts to be a repetition of 

 the reports on the Salt Eange I made to Goverment in 1848. These 

 were drawn up after a very rapid inspection of the Eange between 

 Baghanwalla and Kalibag, in the month of April, a period of the 

 year, when it is next to impossible to examine satisfactorily such 

 hot and barren hills. 



In the present report I have corrected several errors, the result 

 of a too cursory examination of the strata, and have added very con- 

 siderably to the matter of my previous reports. 



I regret that I am unable to announce the occurence in the Salt 

 Eange of much mineral wealth, of the existence of which Govern- 

 ment have not already been made aware. 



The nature of the formations precludes the likelihood of any valu- 

 able metallic ores (we except those of iron) being found. The 

 nature and character of the Coal deposits have been fully described ; 

 but, for reasons stated, we fear they will turn out of but little prac- 

 tical value. 



In a scientific point of view, however, I would fain hope that much 

 has been recorded which to Geologists will prove highly interesting.
