or OPARRO, a small island in S. Lat. 27° 36', and in E. Long. 215° 49', which was discovered by Vancouver. This island was supposed to be about six miles and a half long, and it was out of sight of any other land. It is composed of craggy mountains, forming in several places perpendicular cliffs from their summits to the sea, having narrow valleys or chasms interposed. On some of the highest hills were observed some kind of works, resembling fortified places; but as the discoverers did not land on the island, they could not learn their nature and use. In their language and appearance the natives resembled those of the Friendly islands; they seemed acquainted with the use of iron, preferring it to beads and other trinkets, and showed a hospitable disposition. There appeared to be anchoring ground near the north-west end of the island.
