Whangpoo

Firing by Japanese warships upon the Chinese Woosung forts, at the mouth of the Whangpoo River twenty miles below Shanghai, began at 11:30 A.M. today, according to the Japanese Consulate, which charges that guns of the forts opened fire first, bombarding passing Japanese warships.

Some large vessels that do not wish to berth in the Whangpoo anchor in the roadstead off the entrance to the river and discharge into lighters. The greater number of ocean-going vessels, however, proceed up the Whangpoo to Shanghai.

Shanghai does not escape the problems besetting delta cities. It lies about 14 mi. (23 km.) I above the mouth of the Whangpoo River (Huang-p'u Chiang), a small tributary of the Yangtze near its estuary. Daily, rising tide water from the Pacific shunts Yangtze River water up the Whangpoo.
