NAUTICAL INTELLIGENCE. LIGHT-TOWER AT BRUSTERORT. FROM the 15th December, 1846, a light will be placed on the light-tower which has been erected at Brusterort, instead of the two beacons which have hitherto been lighted. The tower stands in 50° 57′ 50′′ north latitude, and 19° 59′ 30′′ longitude 1hr. 19' 58" in time from Greenwich, and is built in octagon form of rough brick. The base of the tower is 107 feet, 2 inches, 8 lines above the medium height of the Baltic; the axis of the light 82 feet above the ground; consequently 189 feet 2 inches, 8 lines above the medium level of the Baltic sea. The light is a Fresnel fire of the second rank, to common view a fixed light, which however is interrupted from 4 to 4 minutes by a brighter glare, which is preceded and followed by a short obscuration. It illumines 5-6 of the horizon from S. W. to S. S. E., and may be seen from on board a small vessel, at 10 feet elevation of the observer above the level of the sea, 5 geographical miles; at 30 feet elevation of the observer, 54 geographical miles; from the masthead of a large vessel, at 100 feet elevation of the observer above the level of the sea, 7 geographical miles. Koenigsberg, 14th November, 1846. ROYAL GOVERNMENT, SECTION OF THE INTERIOR. HALIFAX.-LIGHT-HOUSE ON BEAVER ISLAND. A light-house has been recently erected and is now in operation on the south end of the outer Beaver, or William's, Island, to the eastward of Halifax, and is a revolving light, visible 14 minutes, and dark a minute; the lantern is placed on a square building 70 feet above the level of the sea, and is painted white, with two black balls painted on the seaward side to distinguish it in the day-time. The following bearings and distances have been taken by order of Admiral Sir F. W. Austen, the naval commander-in-chief on this station, as follows:Latitude 44° 47′ 49" N., by meridian altitude of sun; 25′ 18′′ W., or 1° 12′ 30′′ E. of the dock-yard, Halifax. Harbor Rock,. longitude, by chronometer, 62° Variation 19′ 00′′ W. W. Goose Island Point and Sutherland Island Point, in one, N. 18 A reef extends from the east end of Beaver Island a considerable distance, so that on entering the bay you should give the light-house a berth of three-quarters of a mile. This harbor is a good one. Inside Beaver Island the anchorage is not very good, but further up the bay there is a good anchorage, by giving the light a berth of half or three-quarters of a mile, and steering N. N. W. S. CUNARD, Commissioners of A Fog Bell, worked by machinery, has been erected on the southwest light-house on St. Paul's island, off Cape North. LANTERN ON THE LIGHT-TOWER OF THUNOE. The lantern on the light-tower of Thunoe has been heightened one and a half feet, and replaced by an iron lantern, with large glass squares, which since Sept. 10, 1846, has been kept burning during the same hours as all other Danish lights, and is being visible over the whole horizon at the distance of three German miles. ANTON LIZARDO, SACRIFICOS, AND GREEN ISLAND. ERROR IN CHARTS-DIRECTIONS FOR ENTERING THE HARBORS. The annexed letter from the commander of the United States ship Princeton, dated on board U. S. ship Princeton, Anton Lizardo, 5th January, 1847, contains important information for navigators coming from the North: SIR-There are a number of vessels coming from the North to this anchorage, and if they run by the charts they must go on shore. The chart of Sir John Philliman, of 1824, calls Blanquilla, (forming the entrance to this, one of the best harbors in the world,) an island, when it is a shoal. Directions for entering Anton Lizardo, Sacrificos, and Green Island, cannot be mistaken. Therefore bring N. W. by N., and steer S. E. by E., (compass bearing,) this will carry you in sight of Blanquilla, a shoal which breaks. When you are two miles from Green Island you can see a blank on the hills on your larboard bow; there are a number of patches, but this is the largest and most southerly-steer for it. As you approach, you will observe the houses and lime-kiln on Anton Lizardo, steer for them, keeping them open on the larboard bow, until you near Blanquilla shoal; as you pass in, keep a cable's length from the light green water, the shoal on your larboard hand. You will be steering about S. E. by E., doubling to E. N., (you will now be one mile from the beach where there is a breaker thence extending from 300 to 400 yards towards Blanquilla,) here your eye and lead are your best guide; do not go in less than 6 or 8 fathoms on the Blanquilla side of the channel. If you shoal your water, steer towards the shore, and you will deepen from 8 to 16 fathoms, and from 16 quick to 8 and 2 fathoms. The channel is half a mile wide at least. As soon as you pass Blanquilla, or as soon as it is on with Salamidinilla, which is the southern and eastern island, you can haul up gradually to the eastward, steering where you please. Blanquilla bears W. N., and Salamidinilla N. N., from this ship; we are in 6 fathoms water, good holding ground, about 1 mile from the island, where at present you will see coal, a small house, etc. Very respectfully yours, etc. F. ENGLE, Commander. FLOATING LIGHTS ON THE COAST OF IRELAND. The Corporation for preserving and improving the port of Dublin have given notice, that on and after the 1st January, 1847, gongs will be substituted for the fog bells at present in use on board their light-ships, viz. :— The light-ship at the north end of the Kish Bank. The light-ship near the south end of the Arklow Bank. The light-ship near the Coningbeg Rock (Saltees.) And after the period above mentioned, whenever the weather may be thick and foggy, so as to require such signal for the safety of shipping, a gong will be sounded on board each of these light-ships, of which masters of vessels navigating the St. George's Channel are requested to take notice.

IMPORTS OF SPERM AND WHALE OIL, From January 1st, 1838, to January 1st, 1844, and Oil and Bone, from January 14th, 1844, to January 1st, 1847. STATEMENT OF SPERM AND WHALE OIL, AND WHALEBONE ON HAND, JANUARY 1, 1847. Henry P. Havens, Esq., of New London, has furnished us with the following additional particulars to the article which appeared in the Merchants' Magazine for January, 1847. They were intended to accompany that article, but were received too late. The North Pacific Ocean, from coasts of America and Kamtschatka, lat. 35° to 60°, called northwest coast, is the "ground" where most of the right whale oil taken by American ships is procured. The large size and abundance of whales in this region have attracted a large proportion of the vessels engaged in this department of the business; and it is estimated that 315 ships from the United States have fished there during the present year. The whales are taken here during the warm months, say from 1st May to 1st October. It is believed that the North Pacific was first visited for right whales in 1839. The following table will show the success of the vessels cruising on that ground since that time : |
