CHINA SEA.
Chinkiang District-Yangtze River.
PITMAN-KING CHANNEL MARKED FOR NIGHT NAVIGATION.
REFERRING to Special Notice to Mariners No. 546, notice is hereby given that the following alterations have been made in the marking of the Pitmau-King Channel, Yang- tze River, to aid its navigation by night:-
The Kiushan Bank Light-beacon has been discontinued.
A Light-beacon, to be known as the Pitman Beacon, has been established on the northern coast of Pitman-King Island to mark a point where vessels make or leave the steep-to coast of the island when navigating between the south-western end of Kiushan Bank and the shoal off the northerly point of Pitman-King Island. This Beacon, which is situated 6·22 miles S. 874 E. from Kiushan Quoin Beacon, exhibits two white unclassed Lights hoisted vertically and 6 feet apart.
The Cooper Bank Light-boat has been moved and is now moored in 17 feet of water on the south-eastern extremity of Cooper Bank. From the Light- boat, Kiushan Quoin Beacon bears S. 53° W., distant 466 miles. Its characteristics have not been changed.
A Light-beacon, to be known as the Channel Beacon, has been established on the western point of Pitman-King Island. This Beacon, which is a pole surmounted by a black spherical daymark, exhibits a Seventh Order, Fixed, white Light and is situated 132 miles N. 253° E. from Kiushan Quoin Beacon.
The Pitman-King Crossing Lower and Upper Buoys have been discontinued. A Light-boat, to be known as the Crossing Light-boat, has been moored in 19 feet of water on the southern side of the Pitman-King Crossing, and from the Light-boat, Big Tree Beacon bears N. 30° W., distant 1.8 miles. This Light-boat, which is painted red and has one mast surmounted by a black spherical daymark, exhibits two white unclassed Lights hoisted vertically and 6 feet apart.
A red and black vertically striped Buoy surmounted by a black spherical day- mark has been moored in 18 feet of water off the western end of the spit on the northern side of the Pitman-King Crossing. From the Buoy, Big Tree Beacon bears N. 384° W., distant 1.53 miles. This Buoy is to be known as the Spit Buoy and is unlighted.
The Big Tree Light-boat has been moved and is now moored in 48 feet of water on the southern side of the channel in the western approach to the Pitman-King Crossing. From the Light-boat, Big Tree Beacon bears N. 6° E., distant 133 miles. Its characteristics remain unchanged.
The Pitman-King Channel when recently sounded had a least depth of 23 feet on the crossing at its western entrance.
These alterations have been made in consequence of the Kiushan Point (Round) Channel having shoaled to 18 feet in the vicinity of Kiushan Point.
All bearings given are magnetic, and depths are those of low water of extraordinary spring tides.
