om the westward, and therefore
bower anchors should be placed to the south-west and north-west: warps
and the stream cable will be sufficient to secure her from easterly
winds, as the hills rise immediately over the vessel on that shore. If
the run of water outside the bar should fail, holes may be dug at the
edge of the grass, about three feet deep, which will yield a sufficient
quantity in two or three days for any vessel that can pass over it.

The flood-tide in the entrance generally ran sixteen hours, and ebbed
eight hours. High water at full and change took place at 10 hours 10
minutes at night; but on the bar the rise and fall was very irregular,
and a vessel going in should pay great attention to the depth, if her
draught is more than ten feet, for it sometimes rises suddenly two feet.
The spring-tides take place about the third or fourth day after new or
full moon. The variation here is about 7 degrees East. The situation of
Seal Island, from Captain Flinders' observations, is in latitude 35
degrees 4 minutes 55 seconds, and longitude 117 degrees 58 minutes 7
seconds.

A small island was reported in the Sydney Gazette to have been seen in
latitude 36 degrees 27 minutes, and longitude 127 degrees 2 minutes East;
but as the account says, that Kangaroo Island was seen the same day,
which is not less than one hundred and fifty leagues from the above
position, it appears too vague to be correct. (See Horsburgh Supp. page
32.)

BLACK PYRAMID, off the north-west end of Van Diemen's Land, in Bass
Strait, is situated about 4 minutes too much to the southward on Captain
Flinders' chart.

BELL'S ROCK. The following account of a rock, seen by Mr. Bell, the
Commander of the ship Minerva, on her outward-bound passage to New South
Wales, appeared in a Sydney (New South Wales) Gazette, of the 16th of
December, 1824.

"On the 14th of November the Minerva very narrowly escaped striking on a
rock, in the fairway of the west entrance to Bass Strait, on the south
side of King's Island. Reid's rocks bearing North six miles, and the
Black Pyramid East-South-East: from this situation the danger was about
half a mile off (to the southward); but as the water broke only at
intervals of three or four minutes, although the swell was very heavy, it
is probable there may be sufficient depth of water to carry a ship over
it. An indifferent observation made the latitude of the ship at the time
40 degrees 26 minutes."
