Small black buoys have been placed to indicate the
position of the limestone crust discharged on the

bright white light will be exhibited from the most
conspicuous part of the dredger from sunset to sun-
rise.

THE following Notices to Mariners, received from
the Portmaster, Brisbane, are published for
general information.

W. GISBORNE,
(for Minister having charge of the
Marine Department.)

GEOGRAPHICAL SIGNALS, PIONEER RIVER.

GEOGRAPHICAL Signals having been established at
the Pioneer River, masters of vessels who are exempt
from pilotage are reminded that, under the 112th
section of the Navigation Act, they have no claim
to such exemption, unless, when arriving within one
league of the entrance to the Pioneer River, they
show the pendants indicating the port from which
they have sailed.

The numbers used for indicating the port sailed
from are the same as those used at the other northern
ports of Queensland.

Portmaster.

Department of Ports and Harbours,
Brisbane, 12th August, 1879.

FREEMAN'S CHANNEL, MORETON BAY.

By keeping a ship's length south of the buoys in
Freeman's Channel, a vessel will carry not less than
10 feet at low-water springs.

G. P. HEATH, Commander R.N.,
Portmaster.

Department of Ports and Harbours,
Brisbane, 12th August, 1879.

MORETON BAY, NORTH-WEST CHANNEL.

THE following buoys are now laid down in the north-
west entrance to Moreton Bay, namely, -

Off the north extreme of the ( Skirmish Point bear-
Skirmish Banks, a red buoy { ing S. W.; Com-
with staff and cone in 5 } boyuro Point Light-
fathoms. { house, E. S.
Off the south-west extreme of { Point Skirmish bear-
the Spitfire Banks, a black { ing S.W. by S.;
buoy with staff and ball in { Comboyuro Point
5 fathoms. { Lighthouse, E. S.
Off the north extreme of the { Comboyuro Point
Western Banks, a red buoy { Lighthouse bearing
in 4 fathoms. { E. by N.; Cowan
{ Cowan Lighthouse,
{ S.E. E.
Off the south-west extreme of { Comboyuro Point
Yule Bank, a black buoy in { Lighthouse, N.E.
3 fathoms. { E.; Cowan Cowan
{ Point Lighthouse,
{ S.E. E.

A ridge with not more than 4 fathoms at low-water
springs, gradually deepening to 5 fathoms, extends
3 cables W. by N. from the detached 4-fathom
patch, lying mile S.W. by W. from the southern-
most Hamilton Patch.

The northern extremity of the North Banks has
extended about 2 cables to the N.W. since the pre-
sent chart was constructed.

Directions. Vessels about to enter the N.W.
Channel by the opening between the Hamilton
Patches and the North Banks should bring the
Peak of Burwah open to the north of Tibrogargan
(the peak which resembles a broken shaft) about
the width of the former, and keep these marks on
until the eastern shoulder of the range just north
of the Malula River, and 600 feet high, is open of
Caloundra Head. Then steer for the south-eastern
Glasshouse, bearing S.W. by W. As the passage
is entered, the northern edge of North Banks, which
is steep to, will be clearly seen, having 7 fathoms close
alongside. When Culum Hill is shut in its own
width with Caloundra Head-its top showing over
the near land-a vessel may haul up and bring the
right shoulder of the Malula Range on with the foot
of the western slope of the hills forming Caloundra
Head. A S.E. S. course should then be steered,
keeping these marks on until Cowan Cowan Light-
house is brought into line with Leading Hill on a
S.E. E. bearing. The hill should be kept slightly
open to the S.W. of the lighthouse until the black
buoy off the Spitfire Banks is passed. The positions
of the hill and lighthouse should then be reversed
until after passing the red buoy off the north extreme
of the Western Banks, when the hill can again be
brought to the S.W. of the lighthouse, and the
Main Channel past Cowan Cowan Point entered.

The S.E. peak of the Glasshouses is that which is
noted on the chart as 920 feet in height.
