“The Indus has been eroding severely on the right bank, about 30 miles higher up than the erosion which I told you threatened the railway at Rohri on the left bank. The chord of the curve of the bank attacked was over 2¼ miles long, and the erosion at the apex would be as much as 100 feet a day: it amounted to 3400 feet in forty days. It has given us a good deal of trouble, as with a big breach here the water would travel 120 miles before it would be forced back to the river by the hills on the edge of the deltaic deposits, and loop embankments of great length had hastily to be constructed behind the portions of the flood-embankments threatened with erosion. We succeeded with two loops, but with the third had a breach in the weak new loop; the men have been able to keep it from spreading more than 700 feet wide, and have since got it nearly under control.
