C., March 25, 1856. LIGHTS AT THE HARBOR OF PORT LOUIS, MAURITIUS. The following corrected sailing directions for making the anchorage off the harbor of Port Louis, Mauritius, with reference to the lighthouses recently erected upon "Flat Island" and "Cannonier Point," and also the two mast lights near the entrance of the harbor, have been received at this office, and are published for the information of mariners : DESCRIPTION OF THE LIGHTS. FLAT ISLAND. This is a revolving catoptric light of the first order, situated at the southwest or highest extremity of the island, in latitude S. 19° 53′ 26′′, and longitude E. 57° 38' 8", determined by triangulation from the observatory of Port Louis. Variation of the compass 11° 47′ 13′′ west. It Its elevation above the mean level of the sea (the rise of the tide being only about 3 feet) is 366 feet, and it will be visible in clear weather, from the deck of a vessel 13 feet above the water, a distance of about 25 nautical miles. CANNONIER POINT. This is a fixed catoptric light, also of the first order. is situated in latitude S. 20° 0′ 35′′, and longitude E. 57° 32′ 39′′. Its elevation above the mean level of the sea is 39 feet 6 inches, and it will be seen from the deck af a vessel 13 feet above the water, a distance of about 10 nautical miles. The objects of this light are to indicate the position of a dangerous shoal nearly 1 miles from the shore, and to keep vessels clear of the coral reefs to the northeast and southwest of the point. HARBOR MAST LIGHTS. One of these is placed as a leading light (red) at the Martello Tower, at the mouth and on the left bank of the Grand River; and the other (green) at Fort George, on Tonnelier Island. GENERAL DIRECTIONS. Vessels making the land from the eastward (windward) side of the island should give a berth of 24 miles to the reefs of Amber Island, and be careful not to арproach the light on Flat Island on a course to the westward of N. N. W 4 W., until Gunner's Quoin bears west, when they may shape a mid-channel course between Gunner's Quoin and Flat Island. When to the westward of the Quoin, the light at Cannonier Point will become visible, and must be approached with the Flat Island light bearing astern E. N. E.N., until abreast of Cannonier Point, when that light will bear S. E. by S., a berth of rather more than two nautical miles being thus given to the dangerous reef and shoal off the point. They may then haul up to S. W. by S. for the anchorage, distant about ten nautical miles, taking care to keep the Cannonier Point light white for a distance of 64 miles, when the Flat Island and Cannonier Point lights will appear in one; the change of this color to red, within that distance, will indicate a too near approach to the land. The red light at the mouth of the Grand River will now be opened, bearing S. S. W., for which vessels may safely steer until the mast light (green) upon Fort George, on Tonnelier Island, bears S. E. S., when they may immediately let go the anchor, being on the best ground. A nearer approach to the light at Grand River would bring them too close to the reefs. If the night is clear, the "Corps de Garde" mountain will be clearly seen in line with the Grand River light. It is, however, generally advisable for vessels passing Cannonier Point at night to lay-to, keeping sail occasionally upon the ship for the purpose of maintaining a good position for making the anchorage at day-break, in preference to attempting it at night, by which, in a very few instances, any time will be gained. Considerable risk, as well as the necessity for anchoring outside at all, will also be thus avoided. E. C. FROME, Surveyor General. By order of the Lighthouse Board, TREASURY DEPARTMENT, OFFICE LIGHTHouse Board, THORNTON A. JENKINS, Secretary. LIGHTHOUSE AT CAPE FLORIDA. Notice is hereby given that the lighthouse tower at Cape Florida has been elevated twenty-six feet, and surmounted by an iron watch-room and lantern, and furnished with a catadioptric apparatus of the second order, fixed, illuminating 315° of the horizon. The focal plane of the apparatus is 100 feet above the mean sea level. The tower and lantern are painted white (as before.) The new light was exhibited for the first time on the night of the 18th inst., and will continue to be shown from sunset to sunrise till further notice. By order of the Lighthouse Board, KEY WEST, FLORIDA, March 23, 1856. GEO. G. MEADE, Lieutenant Topographical Engineers. SWEDEN, WEST COAST-BUSKAR LIGHT, WINGA SOUND. Official information has been received at the office of the Light-house Board, that the Swedish Royal Marine Department has given notice that the Buskar Light, in Winga Sound, in the Kattegat, at the entrance to Gothenborg, which, since the 1st September, 1854, has shown a red light to seaward and a bright light towards the Sound, has been partially altered, in order that it may be seen farther off. It now shows a bright light to seaward to a vessel at a distance, but |
