220 WYNNE : TRANS-INDUS SALT REGION, ROHA.T DISTRICT. 



patches ; the salt is nearly horizontally stratified, and the outcrops from 

 5 to 30 feet in height. This salt, dissolving under the atmosphere, covers 

 itself with a layer of the clay which it contained ; it is of the same 

 character exactly as that at Bahadur KM. — A. B. W. 



25. Sappdrrij a salt locality in the hills south-west of Bah&dur 

 Khel, close to the British Frontier. The salt was not seen, only a 

 strong saline efflorescence, and it was said to have been concealed by a 

 fall of debris. The place is just at the watershed between the Changosh 

 and the Bahadur Khel streams.— A. B. W. 



Besides the above there are a few smaller salt exposures near the 

 others, sometimes called by separate names ; thus Lukki and Kotkulli 

 between Sirraikhwa and Kurruk, where a little salt is seen. 



Total outcrop. — If the working quarries be included with the 

 localities just mentioned, the exposures will number at least 335, exhibit- 

 ing, when approximately although very roughly estimated, 3,082,996 

 superficial feet of rock-salt. 



Total quantity of salt. — If the above exposures of salt be supposed 

 to have a thickness of only 100 feet, the quantity present might be 

 estimated at 500 millions of maunds, equal to the present demand 

 for 1,000 years, but this estimate would be unreasonably low, for, 

 in attempting to calculate the quantity, we must remember that 

 the area of at least all neighbouring ground in which salt is pro- 

 bably concealed should be included, and then it would have to be 

 reckoned, not by square feet, but by square miles. The Bahadur Khel, 

 all but naked rock-salt, is four miles long and a quarter of a mile 

 wide, giving one square mile of area : the Malgheen (M algin) , Jatta, 

 Barbarra, Gooroozi, and Narree (Narri) quarries may be taken at a 

 quarter to a fifth of a mile each, but these are only some among many 

 localities, so that an area of five square miles may be fairly supposed to 

 represent the space in which rock-salt is pretty certain to exist (though 

 it may really be much greater) . The salt strata measure 1,000 feet 

 thick at one place at Bahadur Khel, but taking the thickness for the
