Viwa is 100 feet in height.^ Plateau off Nandi and Yasawa. To the westward of Nandi waters (Plate 3), off the northwest coast of Viti Leva, extends a wide plateau, the result of the denudation and submarine erosion of that side of the island. The depth of this plateau is most irregular, varying from ten to forty fathoms. The plateau is studded with sunken patches, and with rocks and islets and islands. The southwestern line of islands from the Mololo Islands to Mana is flanked by an outer line of reef flats, which gradually become smaller and disap- pear off Tartar Reef (Plate 3). From these the edge of the plateau crosses toward the north, and the outer reefs reappear again to the westward of the long chain of the Yasawa group. The Yiwa Island reef is separated by a narrow, deep channel, with 137 fathoms in mid-channel, from the western edge of the Yasawa plateau. To the northwai'd of the Malolo Islands are scattered a few islands, — Kandavu, Lovuka, Tavua, and Yomo. The last is of volcanic.
