Liptrap, the next headland to the eastward.
(*Footnote. The result of the tidal observations made at Shortland's
Bluff, gives 12 hours 20 minutes for the time of high-water on the full
and change days. The simultaneous ones made in other parts of this great
sheet of water during our stay, gave the times of high-water later as
follows:
At William Town: 1 hour 0 minutes.
Under Arthur's Seat: 1 hour 45 minutes.
At Corio Harbour: 2 hours 30 minutes.
At the entrance of Port Phillip the rise at springs is only three feet
and a half, when the stream makes in at 2 hours 0 minutes. It also
continues to run out from one to two hours after the water begins to rise
by the shore. The outward and inward streams differ considerably; the
latter being from 5 to 5 1/2 hours' duration, whereas the former is from
6 to 6 1/2 and 7. The outward stream between the heads sometimes attains
a strength of nearly 7 knots, and when opposed to a southerly gale,
causes a sea dangerous to small craft; these gales heap the water up in
all parts of the bay, particularly at William Town in the northern
corner. On such occasions there is scarcely any fall of tide perceptible
near the entrance; the outward stream is then also much weaker. In the
West Channel the flood and ebb-streams have a velocity of from 1 to 2 1/2
knots; but in the south it seldom exceeds two. Above the banks or in the
inlet leading to Corio harbour there is scarcely any stream of tide
perceptible; but through the channel over the bar at the latter the flood
runs nearly three quarters of a knot. Outside the entrance the ebb sets
between South by East and South-South-West for seven miles, when its
strength is weakened to about a knot; from thence it trends more westerly
towards the mouth of the Strait.)
CAPE PATTERSON.
Five and seven miles to the westward of Cape Patterson there are two
rivulets, near the former of which an inferior kind of coal crops out; it
occurs in beds of the carboniferous series. Between the two headlands
above mentioned the shore falls back, forming a bight six miles deep, at
the head of which is Anderson's Inlet, six miles in extent, full of mud
banks, and available for boats only. A river, called Toluncan by the
natives, empties itself into the head of it.
(*Footnote. The observations on the tides at this place make the time of
high-water at the full and change days 1 hour 10 minutes, when the rise
is 8 feet. The stream in the main channel runs up
