1928 · 174745 — Likely Shanghai: 1928-34. Mariners are warned to exercise due caution when approaching and when in the waterways A collection of otherwise untraced notices to mariners compiled by a civilian captain who plied the lower Yangtse during the late 1920s and early 1930s. Yangtse shipping was regulated by the Maritime Customs Service which issued around 100 navigational advisories per year. During the late 1920s shipping traffic on the Yangtse rebounded after several years of decline during the Warlord Era. Low water however continued to pose problems for navigators and increased the need for effective river management. The 39 notices are technical directions concerning specific parts of the channel. They specify when vessels may and may not enter stretches of water warning of the persistent presence of Chinese craft not subject to the same notices offer guidance for navigating buoyed channels provide optimum bearings and relay a change to the position of the Bend and Gravener Island beacons due to the erosion of the channel.
