All Bearings Magnetic, unless otherwise stated. 85.-ENGLAND.-Entrance to the Thames.-Alexandra Channel. -Alteration of Buoyage.—It is intended to alter the buoyage in the Alexandra channel about the end of March in the following manner, viz. :-A spherical buoy, painted in red and white horizontal bands and surmounted by staff and triangle, will be substituted for the present N.W. Shingles buoy; and the West Shingles, Shingles Elbow, S.W. Shingles, and South Shingles buoys, will be altered from red can to red conical buoys. 86.-ENGLAND.-—West Coast.—Bristol Channel.—Bideford Low Light.-Extension of Illuminated Arc.—With reference to Notice in 1882, it is intended on or about the 12th day of February, 1884, to extend the lateral range of Bideford Low light, so that it shall be shown one point more to the eastward than at present, and three points more to the westward. The full intensity of the light will show from the lighthouse on a bearing of W. to N.N.W. W. 87.-IRELAND.-North Coast.-Lough Foyle Entrance.-Tuns Bank.-Eastern Buoy.—Alteration in Character. The bell buoy marking the eastern end of Tuns bank, north channel to Lough Foyle, has again broken adrift. Owing to the difficulty in maintaining the bell buoy in position, a second class conical buoy, painted red, has been substituted for it, and will mark the danger until further notice. 88.-NORTH SEA.—Jutland.-West Coast.-Intended Light at Lodberg. In the course of the year 1884, a light will be exhibited from a lighthouse at Lodberg (Lodbjerg), northward of Agger, west coast of Jutland. It will be a flashing light, elevated 155 feet above the sea, and visible from a distance of about 18 miles. The lighthouse, constructed of granite, will be 115 feet high. Position, lat. 56° 49′ 25′′ N., long. 8° 16′ 5′′ E. Further notice concerning the character of this light, and the date of exhibition will be given in due course. 89.-NORWAY.-South and West Coasts.-On 1st December, 1883, the following lights would be exhibited on the south and west coasts of Norway : (1.) Grimstad Approach.-Light on Stangholmen.-A quick flashing red and white light, visible seaward between the bearings of N. 31° W. (leading half a cable westward of Haakalboen) and N. 68° E. (leading well southward of Saleskjær and Helleskjær). Position, lat. 58° 18′ N., long. 8° 36′ E. (2.) Grimstad Approach.-Light on Haaren.-A fixed red light, visible in the direction of Stangholmen, and about one point on each side of that line. It is situated 4 cables N. 39° E. from Stangholmen light, and kept in line with it, leads between Stenene and Haaboen, at the distance of half a cable from Haaboen. (3.) Grimstad Approach.―Light on Rivingen.—▲ fixed white light, visible from Riving deep between Lille Haav (Lille Haa islet) and Maagholmboen; and in the direction of Gros, between FladeRivingen and Kraaga. It is situated 4 cables N. 13° W. from Stangholmen light, and kept just open westward of it, leads about one cable westward of Grundsletta, and eastward of Haabogrund. Note.-Approaching Grimstad at night-Stangholmen should be passed close on the starboard-hand, Rivingen light should then be brought a little on the starboard-bow to clear the spit of Lille Haav (with Rivingen light in sight, vessels are clear of Maagholm grund on the west side of the channel); having passed Lille Haav, steer towards Rivingen, which, having passed on the starboard-hand and being within the northern sector of Rivingen light, keep on the eastern side of the sector until past Flade-Rivingen, whence a course may be steered for the red light on Biodden, Grimstad. (4.) Christiania Fiord.-Light and Fog-Signal near Næsodtangen Point.-On Bo shoal, near Nosodtangen (Noes-odden or Ness) point, northern end of Christiania fiord, is a flashing white light, visible in the fairway of the channels northward and southward. Position, lat. 59° 52' 15" N., long. 10° 40′ E. During thick or foggy weather, a bell, placed on Nosodtangen point, will be sounded once every fifteen seconds. (5.)
