MOUNTAINS, HILLS, AND PLAINS 27
the general elevation of the chain drops steadily. But
Fort Munro, the hill station of the Dera Ghazi Khan
district, 200 miles south of the Takht, still stands 6300
feet above sea level, and it looks across at the fine peak
of Ekbhai, which is more than 1000 feet higher. In the
south of the Dera Ghazi Khan district the general level
of the chain is low, and the Giandari hill, though only
4160 feet above the sea, stands out conspicuously. Finally
near where the three jurisdictions meet the hills melt
into the Kachh Gandava plain. Sir Thomas Holdich's
description of the rugged Pathan hills applies also to
the Suliman range. Kaisargarh is a fine limestone
mountain crowned by a fores't of the edible chilgoza
pine. But the ordinary tree growth, where found at
all, is of a much humbler kind, consisting of gnarled
olives and dwarf palms.
Passes and torrents in Suliman Hills. — The drainage
of the western slopes of the Suliman range finding no
exit on that side has had to wear out ways for itself
towards the plains which lie between the foot of the hills
and the Indus. This is the explanation of the large
number of passes, about one hundred, which lead from
the plains into the Suliman hills. The chief from north
to south are the Vehoa, the Sangarh, the Khair, the
Kaha, the Chachar, and the Siri, called from the torrents
which flow through them to the plains. There is an
easy route through the Chachar to Biluchistan. But
unfortunately the water of the torrent is brackish.
Sub Himalaya or Siwaliks. — In its lowest ridges the
Himalaya drops to a height of about 5000 feet. But
the traveller to any of the summer resorts in the mountains
passes through a zone of lower hills interspersed sometimes
with valleys or " duns." These consist of Tertiary
sandstones, clays, and boulder conglomerates, the debris
in fact which the Himalaya has dropped in the course.
