“ Indus at Kafirkot, D.I. Khán dt. feet over sea level. For ninety miles below Attock the river is confined between bare and broken hills, till it finally emerges into the plains from the gorge above Kalabagh, where the Salt Range impinges on the left bank. Between Attock and Kalabagh the right bank is occupied by Peshawar and Kohat and the left by Attock and Mian wall. In this section the Indus is joined by the Haro and Soan torrents, and spanned at Khushalgarh by a railway bridge. This is the only other masonry bridge crossing it in the Panjab. ”
