The beach on the lagoon side is about seven feet high (PI. 179, fig. 2), while on the sea side it is at least twelve to thirteen feet. The shore of the gaps towards the lagoon are flanked on the outer edge with beach rock conglomerate; this is gradually changed into fine coral sand as we reach the edge of the lagoon (PI. 179). A line of breakers extends directly across the gap; the light green color of the water shows there is only a shallow passage between the lagoon and the sea face (PI. 180). We anchored in twelve fathoms, aboi;t three quarters of a mile off Wotje Island. Corals grow in large patches between Our anchorage and the shore, mainly blocks of Porites, patches of Pocillipores, of Millepores, and of Mad- repores ; wide patches of Algae and Nullipores, separated by lanes of sand, extend to seven or eight fathoms in depth. Along the slope of the beaches both the corals and the Algae diminish in number with increasing depth, to twelve or fifteen fathoms, and more rapidly to twenty fathoms. The island of (PI. 227, fig. 4) is fully three quarters of a mile wide; it is formed by a succession of low ridges, â four where we crossed it, â forming sinks, in which the natives have dug water-holes. The ridges are covered with magnificent Pan- danus, breadfruit, and Pouka trees. The belt of vegetation is much finer (PI. 178) than Ska Face of Wotje Island. ^^ ^^^, ^^^^^ ^^^11 ^^ j^^^^g visited. Rolled beach corals are met with across the whole island; on the sea face the island is flanked by a wide reef flat, edged with Nullipore and Pocillipore knolls. The reef flat is about 150 yards in width; it slopes gently; large numbers of coral heads have been thrown upon its surface. The sea beach is at least fourteen feet high, composed in part of shingle, in part of sand. â
