Yamuna and invisible (sub-surface) Saraswati at Allahabad and travelling some
145 km enters Rohtas district of Bihar and passes through Saharsa, Patna, Mungher,
Bhagalpur, Sahebganj and Rajmahal. It swings round the Rajmahal Hills oppo-
site Manihari Ghat and flowing further south enters West Bengal near Farakka in
Murshidabad district. It bifurcates at about 50 km south of Farakka, at Giria in
Murshidabad district. From Allahabad to Farakka where its delta starts, the Ganga's
course is about 960 km. The left arm flows southeast through Murshidabad district
and finally enters Bangladesh at about 56 km further south. This arm, after it enters
Bangladesh, is called Padma. Photograph 2.3 shows the Ganga river at Hardwar.
