tion in South China. If the Southwestern railway system is completed, then Canton will be equal in importance to the two great ports in North and East China, in regard to transportation facilities. The ocean approach of Canton is generally deep excepting at two points which can be easily trained and dredged to enable modern liners to pass in and out at any hour. The deep water line of the ocean reaches up to Lingting Island, where the depth is from 8 to 10 fathoms. Above Lingting, the channel gets shallower (about 3 or 4 fathoms) and runs about 15 miles up to the Fumen Entrance. From this point the water becomes deep again (between 6 and 10 fathoms) right up to the Second Bar—a distance of 20 miles. At the Second Bar, the water is about 18 to 20 feet deep for only a few hundred yards. After crossing the Second Bar, the water becomes deep again for a distance of 10 miles averaging about 30 feet deep up to the First Bar which will be the city limit of our future Canton.
To improve the Approach to Canton, I suggest that two submerged training walls be built at the left side of Canton Estuary above Lingting Island—one from the shore to the head of the Kongsu Bank, and another from the end of the same bank to the head of the Lingting Bank. The first training wall will be 3 to 4 feet under water just at the same level of the bank. The second wall will be from 4 feet at one end to 16 feet at the other, which are the levels of the respective banks which it connects. (See (1) (3) Map XI.) It will cross a channel of 24 feet deep between them. These two
