ROSARIO STRAIT. — BURROWS ISLAND. — LIGHT AND FOG SIGNAL TO BE ESTABLISHED.--About lst April, 1906, a 4th-order fixed white light with a fixed red sector will be established on the western point of Burrows Island, eastern side of the southern part of Rosario Strait, and 10¹⁸ miles N. 29° E. true (N. ⅜ E. e’ly mag.) from Smith Island Lighthouse, on the following bearings:—Point Colville, Watmough Head, S. 50° W. true (S.S.W. ¼ W. w’ly mag.), distant 5¼ miles. James Island, right tangent, N. 47° W. true (W.N.W. ¼ W. w’ly mag.). Cypress Island, left tangent, N. 10° W. true (N.W. by N. mag.). The red sector will extend from N. 48° W. true (W.N.W. ⅜ W. w’ly mag.) to N. 10° E. true (N. by W. ¼ W. mag.) and will cover Lawson Reef, Dennis Shoal, and other dangers lying to the southward of the light-station; but the light will be obscured to the eastward of N. 2° W. true (N.N.W. ¼ W. w’ly mag.) and S. 21° W. true (S. ¼ E. mag.) by the high land of Allan, Burrows, and Fidalgo Islands.

The light will be shown 57 ft. above the water and 27 ft. above the ground, from an octagonal lantern with a black roof, surmounting a white square two-story wooden tower attached to the western front of a white square one-story wooden fog-signal building with a brown roof, and will be visible 13 miles. A white one-and-one-half-story double wooden dwelling with brown roof is located about 100 ft. eastward, and an oil-house and a boathouse are located 50 ft. and 300 ft. respectively northward, from the fog-signal building.

On the same date there will be established at the station a Daboll trumpet, to sound, during thick or foggy weather, blasts of 4 seconds duration, separated by silent intervals alternately of 7 and 25 seconds—thus, blast 4 seconds, silent interval 7 seconds; blast 4 seconds, silent interval 25 seconds.

WM. HALL-JONES.

MOORING OF A WRECK-BUOY, WESTERN ENTRANCE TO SHIMONOSEKI STRAIT.

Notice is hereby given that the lighted wreck-buoy which indicates the position of wrecked third “Iku: a-maru” has been moored in the water off Mutsure-jima, western entrance to Shimonoseki Strait, as notified with the notification No. 50 on the 5th instant.

Fog-SIGNAL, TAIAROA HEAD.--ENTRANCE TO OTAGO HARBOUR.

Marine Department,Wellington, N.Z., 2nd April, 1906.NOTICE is hereby given that on and after Friday, the 20th April, 1906, the following fog-signals will be sounded from a position just below the lighthouse on Taia-roa Head (on the harbour side of it).The signals consist of explosions of cotton-powder charges at intervals of six minutes, and will be made when the land is likely to be obscured at a distance of about three miles from seaward by either fog, mist, falling snow, or continuous rain.It is anticipated that these sound-signals will be heard at any distance under ten miles, varying according to the state of the atmosphere and the force and direction of the wind.Special warnings to mariners concerning fog-signals, published by the Board of Trade, are as follows:—“Sound is conveyed in a very capricious way through the atmosphere. Apart from wind, large areas of silence have been found in different directions and different distances from the signals, in some instances even when in close proximity to the sound-signal.“The mariner should not assume—“1. That he is out of ordinary hearing-distance because he fails to hear the sound.“2. That because he hears a fog-signal faintly, that he is at a great distance from it.“3. That he is near it because he hears the sound plainly.“4. That the distance from and the intensity of the sound on any one occasion is a guide to him for any future occasion.“5. That the fog-signal has ceased sounding because he does not hear it even when in close proximity.”Charts, &c., affected.—Admiralty Charts Nos. 2411 and 2533. “New Zealand Pilot,” seventh edition, 1901, Chapter viii, p. 293. “New Zealand Nautical Almanac, 1906,” p. 171.WM.
