range, and having reached about three miles inside the pass, I was 

 obliged to return. I hope yet to have an opportunity of seeing what 

 the inside of the Sooliman Range is made of, though I have no doubt 

 it is merely a lower extension of the Salt Range (see Map, supra, 

 p. 191). 



The two outer ranges (for such they appear looking at them from 

 the plain) are evidently portions of an anticlinal slope, the main or 

 chief range (Kala Roh or Black Mountains as it is called) having a 

 distinct ivesterly dip with a scarped face to the E. In several of the 

 water-courses I have seen boulders of Productus limestone ; and, as 

 in several passes brine-streams occur and masses of gypsutti of a 

 most saliferous aspect, I feel assured the time will come when the 

 Salt formation will be found. I cannot learn that salt ever has been 

 found, though natives have told me that the red marl, similar to that 

 which imbeds the salt in the Salt Range, does occur in the interior 

 of the hills. The annexed rough sketch will make the structure of the 



Diagram showing a Section of a part of the Sooliman Range.

range more distinct. As the Sooliman High Range* is of considerable 

 height (pines are visible on it opposite to where I now am), it is most 

 probable that in some of the passes which traverse it some most 

 valuable sections are obtainable, and probably the formation on which 

 the saliferous strata rest may be ascertained. Among the boulders 

 in the pass I visited, I saw a sandstone which I believe belongs to the . 

 Saliferous series. The difficulties, however, in following out any 

 researches in these hills are very great. One cannot go unarmed or 

 without a party, and hence the explorer cannot follow the by-ways, 

 but must keep to the highways. The Bosdars on the Dera Ghazee 

 Khan Frontier, and the Kusranees and Shioranees on the Dera Ismael 

 Khan Frontier, are all robbers and live by plunder, and would be 

 only too glad to get hold of any of us, as we are here to cut them up 

 if they appear on the plains intent on a foray. 



* The Sooliman generally is destitute of trees and almost of brushwood ; and 

 its resemblance to the Salt Range is very great.
