ond Luri the Sutlej runs among low hills through several of the Simla
Hill States. It pierces the Siwaliks at the Hoshyarpur border and then
turns to the south, maintaining that trend till Rupar and the head-works
of the Sirhind canal are reached. For the next hundred miles to the Bias
junction the general direction is west. Above the Harike ferry the
Sutlej again turns, and flows steadily, though with many windings, to
the south-west till it joins the Chenab at the south corner of the
Multan district. There are railway bridges at Phillaur, Ferozepur, and
Adamwahan. In the plains the Sutlej districts are--on the right bank
Hoshyarpur, Jalandhar, Lahore, and Montgomery, and on the left Ambala,
Ludhiana and Ferozepur. Below Ferozepur the river divides Montgomery and
Multan from Bahawalpur (left bank). The Sutle; has a course of 900
miles, and a large catchment area in the hills. Notwithstanding the
heavy toll taken by the Sirhind canal, its floods spread pretty far in
Jalandhar and Ludhiana and below the Bias junction many monsoon canals
have been dug which inundate a large area in the lowlands of the
districts on either bank and of Bahawalpur. The dry bed of the Hakra,
which can be traced through Bahawalpur, Bikaner, and Sindh, formerly
carried the waters of the Sutlej to the sea.

~The Ghagar and the Sarusti.~--The Ghagar, once a tributary of the Hakra,
rises within the Sirmur State in the hills to the east of Kalka. A few
miles south of Kalka it crosses a narrow neck of the Ambala district,
and the bridge on the Ambala-Kalka railway is in this section. The rest
of its course, till it loses itself in the sands of Bikaner, is chiefly
in Patiala and the Karnal and Hissar districts. It is joined by the Umla
torrent in Karnal and lower down the Sarusti unites with it in Patiala
just beyond the Karnal border. It is hard to believe that the Sarusti of
to-day is the famous Sarasvati of the Vedas, though the little
ditch-like channel that bears the name certainly passes beside the
sacred sites of Thanesar and Pehowa. A small sandy torrent bearing the
same name rises in the low hills in the north-east of the Ambala
district, but it is doubtful if its waters, which finally disappear into
the ground, ever reach the Thanesar channel. That seems rather to
originate in the overflow of a rice swamp in the plains, and in the cold
weather the bed is usually dry. In fact, till the Sarusti receives above
Pehowa the floods of the Markanda t
