 lished sources of information, but even if accessible, it is unlikely that 

 they would treat at any length of the geological structure of the country, 

 or its mineral resources. 



Mr. Carne^ Collector of Salt Customs, 1850. — A paper or report on 

 these Trans-Indus Salt Quarries, &c, by Mr. Carne (1850) is referred 

 to by Captain Plowden in his memorandum, and also quoted in Colonel 

 Macgregor's Gazetteer of the Frontier.f The original paper was unfor- 

 tunately not within reach to refer to, but appears to have been a tolerably 

 accurate notice of some of the localities then worked ; with an extract 

 from a report by Mr. P. Melville, Secretary to the Punjab Government, 

 regarding the management of the e mines ' under Sikh rule, when the^ 

 were farmed to the Khan of Teeree (Tiri) for Rs. 6,000 per annum, a 

 further revenue being derived by the imposition of various export duties. 



Mr. Carne's description of the mode of working closely agrees with 

 that by Dr. Warth given in the appendix hereafter, but he mentions 

 the salt of a mine near Shukkurdurra (Shukardarra), of which the name 

 is not given (it may possibly have been either Nandrukki or in the Loon 

 Nallah), as being " striped red and gray salt," associated respectively 

 with marls of the same colour, whence he inferred a passage from the 

 Cis-Indus red salt to the gray Trans-Indus salt. He evidently regarded 

 the salt of both regions as the same, thinking that of this district 

 " perhaps a little sweeter/' 



No such alternation as Mr. Carne describes of red salt underlying 

 red marl or clay, and gray salt underlying marl of the same colour, has 

 since been met with or observed at the places named above or in any 

 other part of the district. As Mr. Carne speaks of the gypsum of 

 Spina as chalk, his geological observation may not have been very close, 

 or he may have mistaken detrital accumulations for rock in situ. 



* Mr. Carne was murdered and is buried at Hurreepoor (Haripur) in Ilazara, one 

 march from Hasan Abdal.
