summit of the hill, 11½ cables west from Bray Rock. The
focal plane of the light is 171ft. above high-water level, and
the light is visible a distance of about sixteen miles.

It shows a fixed white light to seaward between the bearings
of S. 1° E. and N. 61° W., a fixed red light over the North
Banks between the bearings of N. 61° W. and N. 30° W., and
an intensified white sector down the North-west Channel
between the bearings of N. 30° W. and N. 23° W.

[Note: The light may be partially obscured by trees
between the bearings of S.S.W. and S. by W.]

Leading-lights on Briebie Island.—These lights bear in
line S. 55° W. The front light is of the fourth order
dioptric condensing; it is placed in a skeleton wooden tower
62ft. high from ground to lantern-top, and the tower stands
80 yards back from high-water line, bearing S. 10° W.,
distant 4·73 miles from Bray Rock. The focal plane of the
light is 56ft. above high-water level, and the light will be
visible about twelve miles.

It shows a fixed white light to seaward between the bear-
ings of S. 17° W. and S. 77° W., intensified over an arc of
15°, the centre of which is on the line of lights; it is obscured
between the bearings of S. 77° W. and N. 46° W., and shows
an intensified white sector down the North-west Channel
between the bearings of N. 46° W. and N. 40° W.

The back leading-light is holophotal, showing a fixed
white light over an arc of about 15° to seaward, the centre
of which passes over the front light. It is placed on a
skeleton wooden tower 97ft. from ground to top of lantern,
and is 1,060 yards distant from the front light; the focal
plane of the light is 95ft. above high-water level, and the
light will be visible about fifteen miles.

Two gas-buoys, painted black, with can-shaped super-
structures, replace the two black buoys hitherto marking
the western extremity of the Spitfire Banks and the western
side of Yule Bank respectively; and one gas-buoy, painted
red, with conical superstructure, replaces the red buoy
hitherto marking the northern extremity of the Western
Banks.

From the black buoys a fixed white light is shown; and
from the red buoy an occulting white light, visible four
seconds, eclipsed two seconds, is shown; the focal plane of
the lights is 10ft. above water-level, and the lights will be
visible about three to four miles.

Additional Black Buoys.—Three additional black buoys,
marking the eastern side of the North-west Channel, are
placed on a line joining the buoys marking the northern ex- remity of the North Banks and the western extremity of the
Spitfire Banks on the following bearings, viz.:—

Buoy in 8 fathoms:
Caloundra Lighthouse, bearing N.W. by N. ½ N.
Mount Beerwah, bearing W. ½ S.

Buoy with top-mark in 10 fathoms:
Caloundra Lighthouse, bearing N.W. by N.
Mount Beerwah, bearing W. ¼ N.

Buoy in 9 fathoms:
Caloundra Lighthouse, bearing N.W. ⅜ N.
Mount Beerwah, bearing W. ¾ N.

Buoy-numbers.—The black buoy marking the northern
extremity of the North Banks will be numbered NW1, as
before; the additional buoys will be numbered NW3, NW5,
and NW7 respectively. The Spitfire Bank gas-buoy will be
numbered NW9, and the Yule Bank gas-buoy will be num-
bered NW11. The Western Banks gas-buoy will be num-
bered NW4.

Buoys Nos. 1 and 5 will carry top-marks.

Directions by Night.—Vessels from the southward, after
rounding Cape Moreton, should steer a course for Caloundra
Light, keeping both the Yellow Patch and the Caloundra
Light white until the Briebie leading-lights come in line bear-
ing S. 55° W. Keep the latter in line, passing through the
red sector from Caloundra Light until in the white sector
from that light, then haul up and bring the light astern
bearing N. 25° W. until through the obscured sector of the
front leading-light, and when the white sector from the latter
is entered keep within its limits until the Spitfire Bank gas-
buoy is visible, when steer to pass it on the port hand at a
distance of about three cables; thence steer to pass the
Western Banks gas-buoy on the starboard hand at a distance
of about three cables off; then steer to pass the Yule Bank
gas-buoy on the port hand at a distance of about four cables,
and then steer for Cowan Cowan Light, bearing S.E. ¾ E.
until the bright white sector from Comboyuro Light is
entered, when bring that light astern bearing north, and
continue, passing through the obscured sector from Cowan
Cowan Light, until the Cowan Cowan Light opens out bright
again, when bring it astern, and, keeping within the limits of
that sector, steer a course across the bay for the anchorage
near the Pile Light.

Vessels from the northward must approach the entrance,
keeping Caloundra Light white until the leading-lights are
in line, when proceed as directed above.

Directions by Day.—Vessels from the southward, after
rounding Cape Moreton, should steer for Caloundra Head,
keeping Cape Moreton Lighthouse open east of the Outer
White Patch until the light-towers on Briebie Island come in
line bearing S. 55° W., or until the S.E. Glasshouse Moun-
tain (marked 920ft. on chart) comes in line with the front
leading lighthouse. Steer in on that line until Coolum Hill
(600ft. high) is shut in its own width with Caloundra Head—
its top showing over the near land—or until Caloundra Light-
house bears N.W. by N. ¾ N.; then steer S. 36° E., rounding
the black buoy with top-mark on the north extreme of the
North Banks, passing three more black buoys on the port
hand, the middle one of which carries a top-mark, and the
Spitfire Bank gas-buoy. Pass the latter at a distance of
about two to three cables, and steer to pass the red gas-buoy
on the Western Banks on the starboard hand at a similar
distance; then steer to pass the Yule Bank gas-buoy on the
port hand at a distance of three to four cables; and then
steer for Cowan Cowan Lighthouse, keeping Cone Hill just
open south of the tower until the red buoy on the East
Knoll Bank is visible, when steer to pass it on the starboard
hand at a distance of about four cables, and continue until
Mount Campbell, bearing N.E. ½ N., is just open south of
Cowan Cowan Light. Keep these marks in that position,
and continue on across the bay to the roadstead.

Vessels from the northward should not bring Coolum Hill
west of the summit of Cartwright Point before running down
the line of leading-marks; then proceed as directed above.
