43 degrees 48 minutes East, the course to the entrance of Port
Phillip, is North-East 1/2 North seventy miles; the soundings will be
found, at first, to decrease rapidly, and in the parallel of Cape Otway
the depth will be 47 fathoms, fine sand and shells. Further particulars
respecting the quality of the bottom off this part of the coast will be
found in the first volume.

A South-East 1/2 East course 176 miles, from the same position, will take
a ship to Port Dalrymple. In the first twenty-nine miles of this
distance, the soundings will have decreased to nearly 30 fathoms, and the
ship's place should be then abreast of the North-East end of King Island,
distant ten miles. The sight of this and, further on, of the Hunter
Group, which should be passed at a distance of 20 miles to the
South-West, will show if the right allowance has been made for the set of
the tides. In the courses given in this note, the tidal influence has not
been noticed; but I have above noticed the direction of the streams, and
the allowance to be made will of course depend on what stream the ship
enters or leaves the Strait with.

Again, from the same position, an east course, 136 miles, will place a
ship four miles to the south of the Curtis Isles. The soundings will be
found to decrease to 40 fathoms thirty miles to the eastward of King
Island, and will continue within a fathom or two of that depth for the
remainder of the distance.

Two hundred and four miles from the above position, on a North-East 1/4
East course, will take a ship to abreast of Cape Howe, distant twenty
miles; passing midway between Hogan and Kent Groups, distant nearly nine
miles from each, at which time twenty-eight miles will have been run on
the above course. In passing the latter group, attention should be paid
to the set of the tides; as with the flood-stream and a northerly wind
vessels may be obliged to pass on the south side of it. Cape Howe bears
from Kent Group, North 36 degrees East, 170 miles. When a ship gets into
30 fathoms she will be within 8 miles of the North-East side of these
islands; and on the opposite she will have that depth half the distance
off.

It only now remains to notice the tides in the passage north of King
Island. It is high-water on the full and change days at 1 o'clock; the
stream begins to set to the South-West three hours and a half before
high-water, running with a velocity of from 1 to 2 knots; past the
Harbinger Rocks, however, i
