From a continual column of smoke which was seen daily ascending from the middle of Amattafoa, it was judged that there was a volcano in that island.
Anamocka was first discovered by Tasman, and by him was named Rotterdam.

It is of a triangular form, and each side extends about three and a half or four miles.

From the north-west to the south of the island, round by the east and north, it is encompassed by a number of small isles, sand-banks, and breakers.

An end could not be seen to their extent to the north, and they may possibly reach as far to the south as Amsterdam or Tongataboo.

Together with Middleburg, or Eaoowe, and Pilsart, these form a group, containing about three degrees of latitude, and two of longitude.
