CALIFORNIA.

SAN FRANCISCO BAY ENTRANCE.—SAN FRANCISCO LIGHT-VESSEL NO. 70 REPLACED ON STATION. — RELIEF LIGHT-VESSEL WITHDRAWN.—Referring to Notices to Mariners Nos. 50 (2269) and 51 (2313) of 1906, further notice is given that on 11th February, 1907, San Francisco light-vessel No. 70 was replaced on her station about 3¼ miles outside the bar, off the entrance to San Francisco Harbour, 10⅔ miles S. 72° 20′ W. true (S.W. ⅔ W. mag.) from Fort Point Lighthouse, and about 500 ft. northward of the range-line marked by Fort Point light and Alcatraz lights, and relief light-vessel No. 76 was withdrawn.

No change has been made in light-vessel No. 70 as to the characteristics of her lights, fog-signal, or general appearance.

CAPE MENDOCINO.—BLUNTS REEF LIGHT-VESSEL NO. 83 WITHDRAWN FROM STATION.—RELIEF LIGHT-VESSEL.—About 20th March, 1907, Blunts Reef light-vessel No. 83, located 1⅔ miles S. 61° 20′ W. true (S.W. ⅓ S. mag.) from Blunts Reef, off the sea-coast of California, and 4½ miles S. 85° W. true (S.W. by W. ⅔ W. w’ly mag.) from Cape Mendocino Lighthouse, will be withdrawn from her station for repairs, and the station will be marked by relief light-vessel No. 76.

Relief light-vessel No. 76 shows, like light-vessel No. 83, 2 fixed white lens-lantern lights, each from three lanterns encircling the masthead, but these are 46 ft. above the water, and visible about 12 miles.

During thick or foggy weather light-vessel No. 76 will sound a 12 in. steam-whistle with the same characteristic as that sounded from light-vessel No. 83—viz., blasts of 2 seconds’ duration, separated by silent intervals of 28 seconds.

Relief light-vessel No. 76 is a flush-deck steam-vessel, has two masts, schooner rigged, no bowsprit, a black smokestack and a steam-whistle between the masts; but differs from light-vessel No. 83 in having all visible parts from the bow to the middle of the foremast, and from the middle of the main-mast 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. 83 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.

No change will be made in light-vessel No. 83 as to the characteristics of her lights, fog-signal, or general appearance.

SOUTH PACIFIC OCEAN.

NAURU OR PLEASANT ISLAND. — MOLE BUILDING.—BUOYS ESTABLISHED.—The German Government has given notice that the commander of the German man-of-war “Condor” reports, under date of 20th October, 1906, that a large black barrel buoy has been moored for the calling-steamer off the west coast of Pleasant Island, South Pacific Ocean, on the following bearings:—

North-west point of island, N. 49° 30′ E. true (N.E. ⅔ N. mag.).

Western point of island, S. 18° 30′ E. true (S.S.E. ⅔ E. mag.).

A large wooden mole, the root of which bears S. 77° 17′ E. true (E. ⅔ S. mag.) from the mooring-buoy, and which extends in a S. 67° 26′ E. true (E.S.E. ⅔ E. mag.) direction across the reef, is under construction. This wooden mole will later be replaced by an iron one.

A small black barrel buoy has been moored for vessels southward of the mole-head and near the reef.

Notice to Mariners No. 28 of 1907.

Marine Department,
Wellington, 19th April, 1907.

THE following Notices to Mariners, received from the Board of Trade, London, are published for general information.

J. A. MILLAR.

CHART COMPASSES.—ERROR IN VARIATION.

COMPASS VARIATION.—Observs. obtained during recent years show that the secular change in the variation of the compass is in some cases greatly different from what was anticipated. The results have been embodied in the variation chart for the Epoch 1907, and this chart should be consulted on all occasions before deciding on the variation to be allowed in shaping course, &c. The compasses on the charts may be in some cases as much as 2° in error. Nov. 1906.

GENERAL NOTICES.

CAUTION WHEN APPROACHING BRITISH PORTS.—Circumstances may arise in which it might be necessary on account of periodical exercises, manoeuvres, or otherwise, to forbid all entr. to the naval ports at night. This is to give notice that on approaching the shores of Great Britain, or any British dependency, if search-lts. are obser. to be in constant operation the naval harb. should be approached with great caution, as it may be apprehended that obstructions may exist outside the port or that the entrs. may be altogether closed, and the exam. service may be in force. In the event of relations becoming strained between this country and any naval power an exam. service will come into force at all the ports in the U.K. and H.M. possessions abroad mentioned at the end of this notice. Masters are warned that before attempting to enter any of these ports they must in their own interests strictly obey all instructions given to them by the vessels which will be charged with the duty of exam. ships desiring to enter the ports, and allotting positions in which the ships shall anchor. In case of fog they should on no account attempt to enter before receiving permission from the exam. officer. The institution of an exam. service at any port will never be publicly advertised, but at all times when the relations of Great Britain with foreign Powers are known to be in a state of tension especial care should be taken in approaching the ports by day or by night, to keep a sharp lookout for the exam. steamer, and to be ready to “bring to” at once when hailed by her or warned by her firing a gun. If an entr. to a port is closed three red lts. vert. by night or three red balls by day will be exh. in some conspicuous position in or near to its approach, and as far as possible notice of this fact will be given by lookout vessels in the offing. If the
