vessel will be clear of the east end of the "Middle
Ground," when a course may be shaped for either
Melbourne or Geelong.

Vessels leaving for sea by South Channel, having
made Eastern Light under Arthur's Seat (Red),
should steer for it until the Pile Light opens out
(Red) upon W. S. bearing, when a course may be
shaped so as to pass it on the north side, and then
steer W. N. through the channel.

Sailing vessels working down, and when to the
northward and in the vicinity of the Middle Ground
and Great Sand, will know they are getting into
danger, when either the South Channel Pile Light
or the Eastern Light under Arthur's Seat shows
White.

They will also know their proximity to the eastern
shore, when the Eastern Light ceases to be visible.

Vessels may find safe anchorage anywhere in Capel
Sound, with the South Channel Pile Light showing
Red; the only danger being the "Hurricane" wreck,
upon which a "wreck buoy" is placed.

PETRIE REEF, WESTERN PACIFIC.

PETRIE Reef, discovered by Lieutenant Petrie, in
1835, and marked Petria (?) on the Admiralty
Charts, was sighted on the 5th March by Captain
Goodall, in the "May Queen." He places the reef
-which he describes as being about 5 miles long
by 3 miles wide-in the following position, viz.,

North Point, latitude 18° 31' 0" S.
Longitude 164° 26' 0" E.
South Point, latitude 18° 36' 26" S.
Longitude 164° 24' 35" E.

On the north-west side he observed an opening
into a lagoon, apparently of deep water. This open-
ing was about two miles wide, with a detached reef
just within the entrance and towards its north-eastern
side. There appeared also to be a small opening at the
southern extremity of the main reef. The sandbanks
on the western and south-eastern sides of the reef
were estimated at low water to be 20 to 25 feet high.
Off the northern extremity of the reef, a strong tide
rip was observed, the stream setting to the north-east.

HYDROGRAPHIC INFORMATION.

Extract from "Remark Book" of Navigating Lieu-
tenant Henry Hosken, of H.M.S. "Pearl."

FIJI GROUP.

Kadavu. -The Astrolabe Reef, which stretches to
the north of Kadavu, is imperfectly delineated on
General Chart 2691. From observations taken when
off the northern extreme of the reef, the North Rock
was found to be a mile too far north. It should be in
lat. 18° 37' S., 1½ mile inside the extreme of the reef.
The reef also stretches 2½ miles further to the east-
ward (abreast the north end of Ono Island) than
shown on the chart.

West Bay, Galoa Bay: Beacons. -There are now
two beacons erected, one on the southern hummock
of Galoa Island, the other on the mainland of Kadavu
Island. When in line of bearing N. 89° W., they
lead through the channel between "Middle Reef"
and "South Reef;" but as they are not placed at
right angles to the passage, they lead dangerously
close to both reefs. The inner beacon in misty
weather is often obscured.

Buoys. -The Mail Company have placed a red buoy
just inside the south edge of "Middle patch;" another
red buoy outside the entrance of the spit which
stretches off the south extreme of Galoa Island; and
a black buoy on the "Centre patch." These buoys
are indifferently moored, and cannot be relied on.

Viti Levu, Navua. -The land about Navua, south
side of Viti Levu, is not correctly laid down on the
General Chart, between the reefs stretching off the
mainland and the reefs north of Bega Island. There
is only a passage of two miles wide, instead of eight
miles as shown on the chart.

Taviuni. -Vuna Point opened out clear of South
Point N.W. N., forming a bay under the reef which
stretches to the westward. Vuna Point stretches out
two miles further than shown on General Chart, which
leaves the extremity of the reef only two miles from
the Point.

Somo-Somo Strait. -Bring Rabi Island to bear
N. E., steer for it, passing between the shoal
patches, which extend three-quarters of a mile to the
west of Goat Island and a number of detached reefs
which stretch off to the eastward from Mount Cocoa-
nut Point about two miles, leaving a channel of not
more than two miles in width. Rabi Island appears
to be placed one mile and a half too far to the east-
ward on the chart.

Goat Island. -A reef surrounds Goat Island,
stretching off about 1' South, West, and 1' North.
Between Goat Island and Taviuni, there is said to
be an intricate channel for small craft.

Anchorages. -The anchorages off Vuna Plantation,
north of Vuna Reef, and the one off Somo-Somo, are
very close inshore, with deep water (15 to 30 fms.),
and circumscribed. The former has very bad hold-
ing ground, but the latter, having soft bottom, affords
fair ground.
