among. barren and rocky hills, and famous for their healing qualities,
as well as for the crocodiles in an adjacent enclosure. Other hot
sulphur springs are to be found at Lakhi in the Kotri tdluka, which
attract a number of pilgrims every year.
In Karachi District the highly interesting geological series of Sind
is most completely developed. It consists of upper and lower Manch-
har beds of upper and middle miocene age, corresponding with the
Siwdliks of Baluchistan and of'the Himalayas; and the Gaj group con-
taining highly fossiliferous marine beds, whose age is lower to middle
Miocene. A second series is the upper Nari or oligocene, consisting
of alternating fresh-water and marine strata; and this gives way in places
to the lower Nāri or upper eocene, a highly fossiliferous Nummulitic
limestone, and to the upper limestone and shales of the Nummulitic
Kirthar group, of middle eocene age, which corresponds with the
Spintangi and Ghazij of Baluchistan. One also finds a lower limestone
and shale group, likewise Nummulitic and classed as Kirthar, but not
known outside of Sind, to which nearly all the Kirthar outcrops in
Karachi District belong. The upper Ranikot, another highly fossili-
ferous marine group, containing in its upper beds the oldest Nummulitic
strata known in India, is approximately on the same horizon as the
London Clay, and alternates with the lower Ranikot-fluviatile beds
with lignites and fossil remains of plants. Other features of the series
are representatives of the Deccan trap basalts ; the Cardita beaumonti
beds, which are lowermost eocene or uppermost Cretaceous; and lastly
the hippuritic limestone. All these rocks outcrop, each in turn, in
a succession of gentle synclinal and anticlinal folds, whose structure
recalls that of the Jura mountains. There is scarcely another part of
the world that contains so complete a development of the Tertiary. The
southern part of tfie District is covered by the Indus alluvium.
Among fruit trees, which are not numerous, the mango, ber, apple, date,
fig, plantain, and pomegranate are noticeable. The timber is almost
entirely babūl ; and the timur or mangrove, found near the salt creeks,
provides firewood for steamers and fodder for camels. Of maritime
plants, the chcizeara and kaudel are common on the coast. The tama-
risk grows in patches which are peculiarly dense in portions of the
Shahbandar tiluka ; while the casuarina has been planted with some
success at Karachi. '
The wild animals found in the hilly portions are the leopard, hyena,
wolf, jackal, fox, ibex, antelope, and gad or wild sheep. Crocodiles are
found at Magar Talao ; and they are also numerous in the pools of the
Hab river, in the Indus, and in some of the large canals and mountain
torrents.
The climate of Karachi city and the neighbouring country, which is
in every direction open to the sea-breeze, possesses a great superiority
