slow down the current and to give a uniform velocity right along the river. So the two-mile wide channel at Whangpoo Junction has to be tabulated into one mile and a half at Kiangyin. See Map VI.
The north or left embankment commencing at Tsungpao Sha continues with the sea wall and makes a convex curve up to Tsungming Island at a point about six miles northwest from Tsungming city. Then it follows along the shore of Tsungming right up to Mason Point and transversing across the north channel parallel to the north shore at a distance of three or four miles right up to Kinshan Point, thence it cuts across the deep channel which was formed in recent years and curves southwestward to join the shore northeast of Tsingkiang and follows the shore line for a distance of about seven or eight miles, then cuts into the land side to give this part of the river a width of one and a half miles from the fort at the Kiangyin side. This embankment from Tsungpao Sha to Tsingkiang Point opposite Kiangyin fort is about one hundred miles in length.
South of Tsungming Island a part of this embankment and a part of the wall that projects into the sea together inclose a shallow space of about 160 square miles good for reclamation purposes. The other part of the embankment, which runs from Mason Point at the head of Tsungming Island to Tsingkiang shore, incloses another space of about 130 square miles.
The right embankment starts at the end of the left jetty of Whangpoo Junction and, skirting along the
