“ A Ferryboat for the Mail on the Indus River near Dera Ismail KhanAt this time of year the River Indus is in full flood, and presents a remarkable sight as, bursting forth from its rocky defile at Kalabagh, it spreads out over the flat alluvial plain of the Western Panjab. In the winter it may be confined to one, two, or three channels, each about one to four hundred yards wide; but in the early summer, swollen by the melting snows of the Himalayas, it overflows its banks, and not infrequently forms a wide expanse of water ten miles broad from bank to bank. ”
