NAUTICAL NOTICES.

All Bearings Magnetic, unless otherwise stated.

84. SCOTLAND.-East Coast.-Tay River.-Dundee.-Railway Bridge Lights.-Owing to the obstruction to navigation in Tay river, above Dundee, near the Tay railway bridge, the channel for passing the Tay railway bridge is now indicated by seven lightsthe two outermost lights being red, the centre lights white. The white lights are shown from the centre of each span for the purpose of directing vessels to the deepest part of the channel, and to avoid passing near the piers. The headway under each white light at high water ordinary spring tides, averages 70 feet. Mariners are specially cautioned to steer directly under the white light. During the day, round signal boards, four feet in diameter, indicate the positions of the lamps on the bridge. Also, two red lights, placed vertically, are exhibited at the north end of the gap in the bridge, indicating proximity to the sunken girders.

85. SCOTLAND. East Coast. Fraserburgh. - Temporary Alterations. The harbour lights are now discontinued; and the north and south harbours closed to shipping, pending harbour improvements. During the period the harbours are closed, a temporary fixed red light will be exhibited on the eastern angle of the north pier head, immediately southward of the entrance channel to Balaclava harbour.

86.-NORTH SEA.-Maas River.-Fog-Signals.-The following fog-signals have been recently established:

(1.) At Hellevoetsluis.-On the east mole head of the Commercial harbour, a bell, during thick or foggy weather, will be sounded when the prescribed fog-signals are heard from approaching vessels.

(2.) At Horned Heads or (Hoornshe Hoofden), on the north share of Haring Vliet, a bell, during thick or foggy weather, will be sounded when the prescribed fog-signals are heard from approaching vessels.

87.-NORTH SEA.-Elbe River.-Light-Vessels I., II., and IV.Alterations, &c.-In consequence of the new light-vessel Gustav

Heinrich having been placed in the position of Elbe No. 1-the light-vessel Caspar (previously No. I.) has been moved to the station, Elbe No. II., taking the place of the light-vessel Neptun— the light-vessel Neptun has been moved to the station, Elbe No. IV., taking the place of the light-vessel Ernst (withdrawn and kept as a reserve light-vessel). The light-vessels are thus named as follows:-Elbe No I. is named Gustav Heinrich (otherwise unchanged); Elbe No. II. is named Caspar, and is moored in 10 fathoms water, the two lights are now elevated respectively 46 and 31 feet above the sea; Elbe No. IV. is named Neptun, and is moored in 10 fathoms, the light is now elevated 36 feet above the sea. Also note that Neuwerk lighthouse is a square massive tower roughly built; and that Brunsbüttel lighthouse is a square tower of a yellowish white colour, constructed of wood.

88.-BALTIC ENTRANCE. Kloster Western Leading Light.-Alteration in Arc of Visibility.— The light (fixed white) is now visible between the bearings N.N.E. through west and S.W. by S., instead of in the direction of the channel only, as previously. Variation, 134° W.

89.-BALTIC ENTRANCE.-The Sound.-Copenhagen.-Leading Lights for Krone Channel.-They are fixed red lights, shown from round towers painted white.

The Low Light, elevated 24 feet above the sea, is shown from the central outer redoubt of the citadel (northward of the Langeline), fronting Castle bay. Position approximate, lat. 55° 41′ 40′′ N., long. 12° 85' 55" E.

The High Light, elevated 40 feet above the sea, is shown from the rampart of the citadel, and bears S.W. W. from the low light, distant 148 yards.

Note. These lights kept in line bearing S. W. W. lead through the entrance of Krone channel in a depth of 21 feet; passing about half a cable eastward of the broom beacon on the south-east port of Tubben bank, and the same distance westward of the beacon buoys marking the north-western edge of Revshalen bank. Variation, 11 W.

90.-BALTIC. Prussia.-Lubeck Bay.-Light near Dahme Head. From a lighthouse recently erected 175 yards within the

high shore near Dahme head (Dahmerhöft) western side of Lubeck hay. It is a fixed and flashing light, showing a flash every five seconds, elevated 108 feet above the sea, and visible through an arc of 252, or between the bearings of S. 74° W. and N. 794° E.; the flashes should be seen from a distance of 14 miles; the fixed light 10 miles. The lighthouse, 94 feet high and octagonal in shape, is of a brownish colour; the keeper's dwelling attached is of a yellow colour. Position, lat. 54° 12′ 10′′ N., long. 11° 5′ 40′′ E. Variation, 12° W.

91.-BALTIC.-Sweden.-Kalmar Sund.-Alterations in Grimskär Light. The flashing white light previously shown between the bearings S. 31° W., and S. 35° W. is altered to a flashing red light. The fixed white light shown westward of the abovementioned sector is altered so as to be visible only to the line of the east point of Svinö islet, westward of which it is obscured. Variation, 93° W.

92.BALTIC. Sweden.-Norrköping. - Leading Light Hrittskär.-Exhibited from a pole on Hvittskär, bearing N. by E. E. from the east point of Grimö, in the fairway of the channel from Pampus bight to Norrköping; it is a fixed red light, visible from a distance of 2 miles. Position approximate, lat. 58° 37' N., long. 16° 12' E. Variation, 81° W.

93.-BALTIC.-Sweden.-Norrköping Bight.-Light on Häfringe Islet. It is a fixed white light, visible from seaward between the bearings N. 28° E. and S. 37° W., and from a distance of 8 miles. Position, lat. 58° 36′ 0′′ N., long. 17° 19' 0" E.

--

Note. This light will be shown when the navigation of the channels surrounding Häfringe islet are not closed by ice. Variation, 8 WV.

94.-NORWAY.-West Coast.-Light on Hest Islet (Hestsjær).From a lighthouse recently erected, the light is visible seaward between the bearings E. by N. and W. by S. S., showing fixed white through the navigable channels, and either flashing white (short eclipses every alternate second), or fixed red over dangerous ground; elevated 75 feet above the sea, and visible from a distance of 15 miles. The sectors of light are shown as follows, viz. :

1. Fixed white in the channel between Tromskarene and Bararmene, the limits leading about one cable clear of those shoals, also clear to the northward of the rocks extending from the shore, and southward of Hallaren shoal-Kvithholmen light is nearly in the centre of this sector. Vessels approaching from the westward, and seaward of Kvithholmen, should keep near the northern limit of this white sector, until past Langbaken shoal (about half a mile eastward of Kvithholmen).

2. Flashing white from one cable south of Baramene, to half a cable northward of Bjogna rocks.

3. Fixed white in the channel, northward of sector 2, to one cable's length southward of Mygrund and Midtfluen (the southern edge of Fuglevingerne with a depth of 5 fathoms on it). Approaching from the westward, when within the limits of this white sector, steer for the light on or about an E. N. course; but with a heavy sea, keep near its northern limit in order to clear the foul ground of 8 or 9 fathoms water, off Hustad. Coming from the northward and nearing Fuglen, Kvithholmen light should be steered for till within this white sector of Hest light, when the course should be altered for that light.

4. Fixed red northward of sector 3, to 2 cabies eastward of Grundkamper (where the depth is 8 fathoms).

5. Fixed white in the Ravngab (Ravneleden), north-eastward of sector 4, to one cable westward of Ravnene (Syd-Ravn). The mid-channel course through the Ravngab is S.E. S.; but, under ordinary circumstances, the light may be steered for when bearing S.E., as Grundkampen only breaks with a heavy sea.

6. Flashing white north-eastward of sector 5, to one cable eastward of Muen-a shoal which always breaks.

7. Fixed white in Kraakeleden, eastward of sector 6, to one cable westward of Kraaken rock. The mid-channel course through Kraakeleden is S. W., but before entering this white sector, mariners must be sure of being southward of Griptarene (Nattergalene).

8. Fixed red south-eastward of sector 7, to three or four cables south-east of Fausken shoal, and the innermost rocks (Disken and Hilboen) of Indgrip (Indgripene).

9. Fixed white in the channel south-eastward of sector 8, to two cables northward of Hammersundsverne. To clear Solverboen, vessels must keep near the southern limit of this white sector. Stavnoes and Kvitbholmen lights serve to guide clear of dangers at Engelen and Rödeggan.

Note. As the channels indicated by the fixed white light (especially by sectors 1 and 3) are very narrow, mariners should bear in mind the character of the sector on each side of the channel they are navigating. Bjogna rock always breaks, and the noise may generally be heard at a warning distance. Bararmene usually breaks. Hallaren, situated nearly midway between Bjogna rock and Hest islet has 2 fathoms water over it. Northward of Hest islet a shelf extends to the distance of one cable, with a depth of 5 fathoms; vessels therefore should pass at a sufficient distance-avoiding also Braka (Braken) rock, lying W.N.W. distant 1 mile from Hest islet, and which always breaks. The light tower, square in shape with dwelling attached, is painted white. Position, lat. 63° 5' 0" N., long. 7° 30' 0" E. Variation, 17° W. Exhibited from 1st August to 15th May following.

95.- NORWAY.- Lofoten Islands.- Lofoten. Alteration in Glopen Light.—South side of entrance to Sörvaagen :- The light (fixed white), is visible from seaward between the bearing E.N.E. and S.W. by S., except where obscured by the land between the bearings N.E. by E. and N.E. N.; and visible from a distance of 16 miles. Variation, 14° W.

96.- MEDITERRANEAN.— France.- Marseille.-Light on Cape Janet, and Withdrawal of Light-vessel.-A lighthouse has recently been erected on Cape Janet, northern side of entrance to the new harbours of Marseille; it shows a fixed white light, varied by a red flash every minute, visible seaward between the bearings S. 45° E. and N. 533 E., elevated 151 feet above the sea, and visible from a distance of 15 miles. The lighthouse, 16 feet high and eylindrical in shape, is constructed of masonry. Position, lat. 43° 20′ 15′′ N., long. 5° 20′ 50′′ E. On the exhibition of Cape Janet light, the light-vessel now marking the northern entrance to the new harbours, will be withdrawn; and the westernmost light (fixed red)
