of kelp was discovered, which was apparently attached. Depths of 10 fathoms were obtained 1½ miles N. 47° 11′ E. true (N. by E. ¾ E. mag.) from North Warrior Rock.

Vessels are recommended not to pass between Warrior Rocks and Stephens Island until this region has been examined, as it appears very likely that dangers may exist.

Dixon Entrance.—H.M.S. “Egeria” anchored in 9 fathoms of water with the centre of West Devil Rock bearing N. 43° 30′ W. true (W.N.W. ¼ W. w’ly mag.), distant 2¼ miles. This shoal appears to be very small in extent and steep-to, with depths of 40 fathoms and upwards all around it.

A shoal, upon which the sea breaks heavily in moderate weather almost continually, has been observed on two occasions ½ mile N 6° 15′ W. true (N.W. by W. mag.) from West Devil Rock. Foul ground, upon which the sea breaks, extends about ¼ mile south-eastward of West Devil Rock. Vessels are recommended to give the West Devil Rock a wide berth.

From the triangulation recently carried out by H.M.S. “Egeria,” it appears that the positions of the north-western extreme of Graham Island and North Island are incorrectly charted.

By the bearing from Cape Muzon (the astronomical position of which has been found by observations to agree closely with that already shown on B.A. charts and on H.O. Chart No. 904) the coast-line in the vicinity of North Island should be about 4 miles farther to the westward. The north point of North Island is correctly shown in bearing from Tow Hill, Graham Island.

A rock, upon which the sea breaks heavily at intervals in a moderate swell, has been observed on several occasions by H.M.S. “Egeria” 1 mile southward of Cape Muzon. The tangents of the land forming Cape Muzon bear from it N. 73° 45′ W. true (W. by S. mag.) and N. 50° E. true (N.N.E. mag.).

The coast-line of Cape Muzon being incorrectly shown on B.A. charts and H.O. charts, the bearings given do not show the correct position of the rock relative to the shore as it is charted.

Vessels should give the shore at Cape Muzon a berth of 2 miles.

SAN FRANCISCO BAY ENTRANCE.—SAN FRANCISCO LIGHT-VESSEL NO. 70 WITHDRAWN FROM STATION.—RELIEF LIGHT-VESSEL.—About 1st January, 1907, San Francisco light-vessel No. 70, stationed about 3¼ miles outside the bar off the entrance to San Francisco Harbour, 10⅞ miles S. 72° 20′ W. true (S.W. ⅞ W. mag.) from Fort Point Lighthouse, and about 500 ft. northward of the range-line marked by Fort Point light and Alcatraz lights, will be temporarily withdrawn from her station for repairs, and the station marked by relief light-vessel No. 76.

Relief light-vessel No. 76 will show two fixed white lens-lantern lights, each from three lanterns encircling the mast-head, but these will be 46 ft. above water, and visible about 12 miles in clear weather. During thick or foggy weather light-vessel No. 76 will sound a 12 in. steam-whistle, giving blasts of 3 seconds’ duration, separated by silent intervals of 27 seconds.

Relief light-vessel No. 76 is a flush-deck steam-vessel, has two masts, schooner rigged, no bowsprit, a black smoke-stack, and a steam-whistle between the masts, but differs from light-vessel No. 70 in having all visible parts from the bow to the middle of the foremast, and from the middle of the mainmast aft, painted red; all visible parts between the fore and main masts, including the middle third of each lantern-mast, white. The day-marks at the mast-heads have five vertical stripes, three red and two white, and on the spring-stay, midway between the two masts, there is an oval day-mark with one white and two red vertical stripes. The number “76” is in white on each bow and each quarter and in black on each side of the spring-stay day-mark. The word “Relief” is painted in large black letters on the middle of each side.

Light-vessel No. 70 will be returned to her station as soon as repairs have been completed, of which due notice will be given, and relief light-vessel No. 76 will then be withdrawn.

HAWAIIAN ISLANDS.

OAHU.—HONOLULU HARBOUR ENTRANCE.—TEMPORARY BUOYS DISCONTINUED.—BUOY ESTABLISHED.—Referring to Notices to Mariners Nos. 14 (551) and 48 (2191) of 1906, further notice is given that about 20th December, 1906, the temporary buoys marking the channel into Honolulu Harbour, with the exception of buoys Nos. 1 and 2, which are now permanent, will be discontinued.

On the same date Honolulu Channel buoy No. 10, a second-class nun, will be established on the eastern edge of the channel, about 975 ft. S. 3° 30′ W. true (S. ⅔ E. mag.) from Honolulu Range front light, to mark the turning-point for vessels going to channel wharf.

BRITISH COLUMBIA.

VANCOUVER ISLAND.—TRIAL ISLAND.—PROVISIONAL LIGHT EXHIBITED.—Referring to Notice to Mariners No. 45 (1989) of 1906, the Canadian Government gives further notice that it has been found impossible to install a permanent lighting apparatus in the new lighthouse on Trial Island, Vancouver Island, by 1st November, 1906. A seventh-order dioptric fixed white provisional light will therefore be exhibited until the permanent light can be put in operation.

Further notice will be given when the permanent light is exhibited.

CHINA.

EAST COAST.—YANGTZE RIVER ENTRANCE.—SOUTH CHANNEL.—TUNGSHA AND KIUTOAN LIGHT-VESSELS CHANGED IN POSITION.—Referring to Notice to Mariners No. 43 (1899) of 1906, the Chinese Government has given further notice that on account of changes in the channel at the entrance to the Yangtze River, China, Tungsha and Kiutoan light-vessels have been changed in position.

Tungsha light-vessel is now moored in 17 ft. at low water, spring tides, 0·6 mile S. 40° 30′ W. true (S.W. ½ S. mag.) from its former position.
