4 WYNNE : TRANS-INDUS EXTENSION OF THE PUNJAB SALT RANGE. 



The late lamented chief of our survey, Dr. Oldham, was deputed in 



1864 to inspect the coal of the Salt Ranere, and 

 Dr. Oldham. . . 



m his report to Government he described the coal 



localities of Kalabagh, Kotli, Chushmea, and Mulla Khel, pointing out 



that the coaly beds occur on two distinct horizons, one in the Jurassic, the 



other at the base of the eocene rocks, and specially noticing the inferiority 



of these coal sources in an economic point of view. He also added some 



valuable observations upon the management of the rock-salt mining 



operations of the Salt Range generally. 



Dr. Warth, formerly in charge of the Salt Range Salt Department, in 



an appendix published with the administration 

 Dr. Warth. rr 



report of the Inland Customs Department, 1870-71, 

 describes the salt quarries of Kalabagh as open workings in a thick group 

 of salt beds ranging from 4 to 10 or even 20 feet in maximum thickness. 

 These salt beds run along the western side of the Lun nala for 2 miles, 

 extending up the side of the gorge as high as 200 feet, and dipping to 

 the west at 70°. There are fourteen working places in this group of rock- 

 salt beds. Dr. Warth/s notes, though short, are correct, and therefore 

 valuable. 



In the Palseontologia Indica, Series ix, page 245, Dr. Waagen records 



the occurrence of Perispkinctes asterianus, a lower

neocomian form of Ammonite, in the Chichan pass, 



deducing thence that this lower cretaceous horizon is represented here. 



My observations with regard to the indication of a cretaceous or neoco- 



mian horizon among the uppermost few feet of the Jurassic rocks at 



Chichali Pass are given at page 277 of the Salt Range Memoir. 



At the time Dr. Waagen and myself visited this section, the identifi- 

 cation of the Ammonite above mentioned appeared sufficient to show that 

 an overlying mass of unfossiliferous sandstone intervening between the 

 Jurassic and eocene groups was probably cretaceous. Since then I have
