Yangtze River--Chinkiang District.

WESTERN ENTRANCE TO PITMAN-KING CHANNEL.

Cooper Bank Crossing Opened to Navigation: Pitman-King Crossing Abandoned.

ALTERATIONS IN AIDS TO NAVIGATION.

REFERRING to Special Notice to Mariners No. 576, notice is hereby given that on the 10th October, 1920, the western entrance to Pitman-King Channel, Yangtze River, by way of Pitman-King Crossing, was abandoned, and a new entrance, named Cooper Bank Crossing, was opened to navigation.

Consequent on these changes in the channels, the following alterations have been. made in aids to navigation:---

A Light-beacon, known as South Light-beacon, has been established on the right bank of the river, 193 miles N. 5040 W. from the Beacon on Kiushan Quoin, to mark a point where vessels alter course when navigating the southern approach to Cooper Bank Crossing. This Light-beacon is painted white, carries a black disc at its middle height, and exhibits two white unclassed lights hoisted vertically and 6 feet apart.

A Light-boat, known as the Cooper Bank Crossing Light-boat, is moored in 23 feet of water on the southern side of the Cooper Bank Crossing, in a position from which the Beacon on Kiushan Quoin bears S. 453° E., distant 334 miles. This Light-boat exhibits a seventh order fixed white light.

The Big Tree Light-boat has been moved, and now marks the fairway in the northern approach to Cooper Bank Crossing. It is moored in 37 feet of water, and from the Light-boat, Big Tree Beacon bears N. 813° W., distant 1:32 miles.

The Crossing Light-boat and Spit Buoy, which hitherto marked Pitman-King

Crossing, have been discontinued.

CAUTION.

Cooper Bank Crossing should be navigated with caution, owing to the strong cross sets of the tides and its liability to rapid change.

All bearings given are magnetic, and depths are those of low water of extraordinary spring tides.
