30 WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB. 



In a passage referring' to the brine spring of Kalra^ near Bakrala^ 

 on the Grand Trunk Road, from Jhelum to Rawal Pindi, the author 

 seems to suppose the existence of a salt-field below. 



The third part of the paper is a preHminary report " Upon the mlt- 

 learmg strata in the eastern part of the range from the Mayo Salt Mines 

 to Jogi Tilla." The geological structure and physical features of the 

 ground are mentioned, and a succession is described differing slightly 

 from that formerly presented by this writer.* 



Dr. Warth corrects Dr. Fleming's statement that " beds underlying 

 the salt marF^ were visible ; he supposes that this appearance is due to 

 a simple case of slippage, and he states that strata older than the salt 

 marl are nowhere seen. 



A fourth part of the report is devoted to the ''Salt mines of the 

 Funjdh Salt Mange, west of Pind-Dadun-Khan" thus furnishing, in 

 conjunction with former reports, a complete survey of the range so far 

 as the salt is concerned. 



The salt quarries of Kalsibagh on the Indus are first described, then 

 the geological structure of that part of the range ; the alum shale mines 

 and alum factories are next noticed (the latter slightly) ; after this all 

 the " beats'' or preventive sub-divisions of the range as far as Makrach 

 are taken up and treated in detail, the physical and geological features

 stone is separated in the following table, which being inverted in the original is here
