The tides follow the direction of the channel, varying in velocity from one to two knots.

PORT PATTERSON.
The reader will be able to have an idea of the large sheet of water these united harbours form, by knowing that Port Patterson is twelve miles long and seven wide at the entrance; though at the upper part, forming the mouth of Bynoe Harbour, it is not half that width.

The latter winds round to the South-East for a distance of 15 miles, with an average width of two, and a depth of nine fathoms.

Thus terminated our exploration in this neighbourhood; the result having been to give this part of the coast quite an insulated character.

The sheets of water creating this new feature, although monotonous with their mangrove-lined shores, still conveyed us many miles into various parts of the continent that had never before been seen by a civilized being.
Another opening of far greater magnitude, and promising in all probability to lead far into the interior now lay before us, at a distance of 140 miles further on the coast to the south-west.
