wood, painted white, and stands at an elevation of eighty (80) feet above the level of the water, bearing from the centre of the upper lighthouse on Shortland’s Bluff south 33 degrees west, distant six hundred and seventy (670) feet.

The leading light will be seen in ordinary weather ten (10) miles to seaward, within the bearings of south one-quarter west round (westerly) to south-west one quarter west.

The two lighthouses by day, and lights by night, kept in one line of bearing, lead in mid-channel between Points Lonsdale and Nepean; but strangers are cautioned not to attempt the entrance by night, nor against the strength of the ebb tide by day.

BEACON ON SWAN POINT.

Mariners are requested to take notice that a cone-shaped Iron Beacon, painted white, elevated fifty (50) feet above the level of the water, has been erected on Swan point, bearing from the low lighthouse on Shortland’s Bluff, north forty one (41) degrees east. This beacon, kept open to the eastward of the low lighthouse, leads in clear of Point Lonsdale reef, and the flagstaff on Shortland’s Bluff, kept half a cable’s length open to the westward of the low lighthouse leads in clear of the Corsair rock, and the other sunken dangers lying off Point Nepean; but in all practicable cases, mariners waiting the turn of tide, entering or leaving the harbour, are recommended to keep the Point Lonsdale shore aboard, as the tide there runs fairer, and in bad weather small vessels incur less risk on the Point Lonsdale shore from the tide ripples than towards Point Nepean.

No alteration has taken place in the Upper Lighthouse on Shortland’s Bluff, which is as heretofore a bright stationary light, one hundred and nine (109) feet above the level of the water, seen in ordinary weather twenty (20) miles to seaward, within the bearings of south round by west to south-west by west.

The bearings are by compass, and heights at mean high water.

FLOATING LIGHTSHIP, HOBSON’S BAY.

A floating light is established at the north end of the West Channel leading into Port Phillip Bay, in the same position as that hitherto occupied by the North Fairway Buoy, which is now removed.

The Lightship is painted Red, and exhibits, between sunset and sunrise, two (2) bright lights, twenty-four (24) feet apart, and fifty (50) feet above the level of the water.

These Lights may be seen from all parts of the horizon within the distance of nine (9) miles in clear weather.

Vessels approaching the Lightship by night or by day, are warned to be cautious in avoiding collision.

The Lightship is moored in four (4) fathoms at low water, with the following magnetic bearings:—

Extreme point of Indented Head N.W. ½ N.
Summit of Arthur’s Seat, S.E. ½ E.
Extremity of Point Nepean S.S.W. ½ W.

ANONYMA ROCK, IN PORT PHILLIP BAY.

Commanders of vessels working up the east side of Port Phillip Bay are requested to take notice that a Chequered Buoy has been placed upon the Eight Foot rock off the Red Bluff, which has been ascertained to lie nearly two (2) miles closer in shore than the position assigned to it in the charts.

Commanders are recommended to notice the following bearings, and lay the rock’s position down on their charts.

Magnetic position of the Anonyma Rock.

Lighthouse, Gellibrand’s Point, N.W. ¾ N.
Centre of the Red Bluff, E. by S.

A small white cliff, some distance north of the Red Bluff, N.E. ½ E.

The Anonyma Rock lies a mile off shore, the least water on it being eight (8) feet at low tide, with five (5) fathoms just outside, and a clear passage half a mile on the inside of it with three (3) and four (4) fathoms, sandy bottom.

CORSAIR ROCK.

A dangerous Rock, with only eleven (11) feet of water over it at low tide, has recently been discovered nearly three-quarters of a mile west of Point Nepean. It is not laid down in any of the charts of this Port.

Commanders of vessels navigating between the Heads are requested to observe the following marks in order to avoid the said Rock (which will hereafter be known as the “Corsair Rock”) and are recommended to lay down its position on their charts as given underneath.

Magnetic Position of the Centre of the Corsair Rock.

Upper Lighthouse on Shortland’s Bluff, N. 21 E.
Middle of the Rocky Islet off Point Nepean, N. 87 E.
Tidal flagstaff on Point Lonsdale, N. 76 W.

The above rock is about twenty (20) feet in diameter, the least water found over it at low tide is eleven (11) feet, with three (3), four (4), and five (5) fathoms water round.

There is a clear passage between the Corsair Rock and the extreme end of Nepean Reef, of about a cable’s length, with three (3), four (4), and five (5) fathoms of water; but no vessel should ever attempt it, as the tide, both ebb and flood, sets with great force on Nepean Reef.
