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.
