walls together with the four-foot Kongsu Bank will act as one continuous wall and will direct the undercurrent which now runs between the left shore and Lingting Bank, into the middle part of the estuary, thus cutting a channel between the bar and the bank of the same name to meet the deep water on the west side of Lingting Island. On the right side of the Canton Estuary, a training wall should be built from the lower part of Fraser Bank in a southeasterly direction across the 24-foot channel into the Lingting Bar ending at the east edge of that bar. (See (2) Map XI.) Thus, with these submerged walls on both sides of the estuary to confine the undercurrent in the middle, a very deep channel can be formed to connect with the Fumen Entrance at one end and the Lingting trough at the other both of which are about 50 feet deep so that a thoroughfare from deep sea right up to the Second Bar of the Pearl River will be created.
These submerged sea walls taken together are about 8 miles in length and will be built only 6 to 12 feet from the bottom of the sea. The expenses will not be much while the acceleration of the natural reclamation process will be very great. Thus, the lands that will be formed on both sides by these walls will far more than repay the expenses of the work of building these walls.
To regulate the Approach of Canton, in that part of the Pearl River from the Fumen Entrance to Whampoa, I suggest that the East River Estuaries be concentrated in a single outlet by using the uppermost channel
