Karāchi stands at the western limit of the Indus delta, in a position therefore comparable to that of Alexandria beside the Nile delta. The railway keeps to the west of the river for more than three hundred miles as far as Sukkur, where is the Lansdowne bridge, eight hundred and forty feet long, between Sukkur and Rohri on the east bank. This is the very heart of the rainless region of India. During twelve years there were only six showers at Rohri. A scheme is under consideration for damming the Indus near this point, in order that the irrigation canals below may be fed, not only in time of flood as at present, but in the season of low water as well.
