bitoy the two lights are on with each other. By the way our plan of Galveston is in a most unfinished condition. Will the collector, or any of our readers, obligingly furnish us with a scale for it?

EAST TONGUE Buoy.-Queens Channel.-It appears, by a notice recently issued from the Trinity House, that the buoy at the eastern end of the Tongue Sand is now a beacon buoy, carrying three distinct beacons to distinguish it from all other buoys in that vicinity.

CHRISTIANIA. Near the light of Fuglehuk, at the entrance of Christiania Fjords, from the 1st of June, a bell will be suspended, with which in foggy weather, when the light cannot be seen at the distance of a quarter to half a league, ten or twelve strokes will be given; at night every quarter, and during the day every half hour.

GRAHAMS SHOAL.-This dangerous shoal lies in latitude 37° 9′ 5′′ north, and longitude 12° 43′ 15" east of Greenwich, which was obtained by a series of angles from known fixed stations on the coast of Sicily and Pantelleria, the atmosphere not being favourable for astronomical observations, although those obtained differed very triflingly from above.

The summit or shoal part of the rock is of an oblong form, it lies north-west and south-east, it is forty fathoms in length, consisting of hard dark coloured pointed rocks with sea weed, the edge (which was clearly perceptible,) is jagged, pointed, and steep. The least depth of water found on it was ten feet, but no doubt much less may be found with a calm sea.

The average depth at the distance of eighty fathoms from its centre twentyfive fathoms cinders, and one quarter of a mile, sixty-five fathoms fine black sand. Fine scollops and other shell-fish with young coral was dredged up. This shoal is extremely dangerous, from the great depth of water around it, and from the various and strong currents that prevail in its neighbourhood, as well as the difficulty of seeing it, for it is visible only at a very short distance.

South-west Peak Pantelleria, south 54° west; Peak Campo Bello, north 5° 50' west; town of Sciacca, north 40° east; Cape Rosello, north 78° 50' east, from bearings found independent of the compass, variation 17° 0′ west. The current set over the lock to east and north, one mile and three-quarters per hour. (Signed) T. ELSON.

COPENHAGEN.-Buoyage of the Sound and Grounds.

THE following translation of a Royal Ordinance, 23rd July last, states that the alterations and changes of the marks in the Grounds, and in the Outer Roads of Copenhagen, specified therein, will be made at the time of placing these marks in the year 1841.

1. The Dragobuoy will keep its former place, but the mark formerly near this buoy will be removed, and in future be moored on the western edge of the Holmetongue in three fathoms water; and the mark near Southern Russe will also be moored in three fathoms water due east, (true bearing) from this shoal; both these marks are intended to remain out all the year round.

2. Large beacons formed of brooms on poles from nine to ten feet long will be placed on the south-east end of the Northern Russe Ground

in three fathoms water. On the north-west edge of the Little Ground in four or five fathoms water. On the north-west edge of the Bredegrund (Broad Ground) in four to five fathoms water. On the east side of the Ravneunger in three to four fathoms water near the stone called Rasmus Moller. The mark on the wreck upon the Middle Ground will exchange place with the buoy now moored on the Old Provesteen, and this buoy will in future be moored near the wreck upon the Middle Ground, and will be provided with a broom on a pole.

3. The marks on the Old Provesteen, the Northern Russe, the Ravneunger, the Southern Russe, and the Drago Sandrevs Tongue will be provided with brooms tied upwards upon black poles. On the contrary the marks on the wreck of the frigate Kronborg, the Middle Ground, the Holme Tongue, and the Little Ground will be provided with brooms tied downwards on white poles.

The mark upon the Broad Ground will be provided with two brooms, the uppermost tied upwards, and the lower downwards upon a pole painted alternately white and black, in order to distinguish this mark from the one on the Little Ground.

4. The northern buoy of the Middle Ground will be removed from the wreck of the line-of-battle ship, the Indfodsretten, back to the northern flat of this ground in twenty-three feet water, and a new mark consisting of a small barrel or buoy painted green will be placed upon the wreck of the Indfodsretten.

The buoy on the Stubb, will be painted red instead of white as heretofore.

The different buoys will have numbers painted upon them as follows: -The Drago Buoy I., Kastrup Buoy II., South Buoy III,, Middle Buoy IV., North Buoy V., Stubbe Buoy 6, and the buoy on the Krone (Crown) 7.

The mark on the Nordhoi (Northill) will be provided with a wooden square one fathom in diameter, painted white, which will be fixed immediately below the Top Beacon, and facing the Hollanderdyb (Dutchman's Deep.)

5. All these marks will be moored or removed generally at the same time with the Light Ship in the grounds, but will not be placed earlier than this can be done with safety, and without fear of being lost or displaced by the ice.

The marks upon the Sandrevstonge, Southern Russe, and the Holme Tongue will remain out the whole year. When the Drago Sandrevs Buoy is removed, in the fall of a mark similar to the others on the west ledge will be moored in its place.

BAY IN ISLE ROTTEE,-Timor.

ACCOMPANYING our present number is a plan of a bay on the south-east side of isle Rottee, (west of Timor) which is said to be much frequented by whalers for refreshment. Notwithstanding we have been unable to

It is about 250 miles from Cape Bougainville, the nearest part of the Australian coast. Whalers it is said are resorting to the neighbouring seas in great numbers and the stock will no doubt be thinned by them.

SUNKEN ROCK IN BASS STRAITS.-There are many unexplored parts in Bass Straits, and the approaches to Kings island are among them. The following danger has not yet appeared in the charts, and mariners must carefully attend to the account given of it by the Port Philip harbour-master:

"Capt. Lewis, the harbour-master, on his late expedition to Kings island, in Bass Straits, in aid of the shipwrecked passengers and crew of the Isabella, discovered a very dangerous rock, nearly level with the sea at low water, and the tide breaking over it at times at high water. The rock is situated in lat. 40° 9′ S., seven or eight miles off the western side of Kings island. In shore, three cables' length, Capt. Lewis found thirteen fathoms' water; next cast no soundings.-Port Phillip Patriot.

QUARANTINE AT ELSINORE.-The following has been received at Lloyd's:-"London, May 4, 1841.-Sir.-I beg to acquaint you, for the information of the committee for managing the affairs at Lloyd's that the Danish Chancery at Copenhagen has issued the following notice respecting the quarantine of vessels arriving at Elsinore and bound for the ports of the Baltic, in so far as the yellow fever is concerned. Only vessels arriving from places infected with, or suspected of yellow fever, whether laden with enumerated articles or not, and on board of which suspicious cases of disease or death have occurred, either on the passage or on arrival, will hereafter be ordered to the quarantine stations, there to discharge, and their cargoes to undergo the process of expurgation. 2. Vessels arriving with enumerated articles from places out of Europe, where the yellow fever has appeared, are subject to an observatory quarantine of fourteen days, provided no suspicious case of disease has manifested itself on board. 3. Vessels with non-enumerated goods, whether such articles be embaled in packages susceptible of infection or not, but otherwise arriving under circumstances similar to those mentioned in 2, are subject to four days' observatory quarantine. 4. Vessels arriving from unsuspected places in Europe, with enumerated articles on board, shipped at such places, are exempt from quarantine, although such articles be the produce of places where the yellow fever actually prevails."

"FRANCIS C. M. MACGREGOR."
