CHAPTER XVII.
Nautical directions, and other detached remarks, by Lieutenant Ball, concerning Rio de Janeiro, Norfolk Island, Ball Pyramid, and Lord Howe Island.
Some notice has already been taken in the preceding sheets of Rio de Janeiro, Norfolk Isle, and Lord Howe Isle; but since they were committed to the press, the following particulars respecting those places have very obligingly been communicated to the editor, by Lieutenant Henry Lidgbird Ball.

As these remarks are the result of minute observation, they cannot fail of being useful and interesting to the seafaring reader, which, it is presumed, will be a sufficient apology for giving them a place here.
There is no danger in going up the harbour to Rio de Janeiro but what may easily be seen.

The course up the harbour is north-west by north; you anchor before the town in seventeen fathoms water, over a muddy bottom; the middle of the town bearing west by north, west, or west by south, about a mile and an half distant from the watering place, and the Fort Saint Cruz bearing south-east.

No pilot is necessary; the soundings a-breast of St.Cruz Fort are twenty-two fathoms, and shoal gradually to seventeen fathoms, where the ships moored a-breast of the town.

The tide flows two hours and thirty minutes at full and change, and rises in general about eight feet.
