EUA ISLAND. 183 



is a little over 640 feet in height, the highest point forming a part of the 

 fonrth terrace (PI. Ill, fig. 3). Along the central part of the eastern face 

 of Eua, the terraces are somewhat indistinct (PI. 113). A large number of 

 caverns are found in the third terrace near the northern point, indicating 

 former lines of elevation between the third and fourth terraces (Pis. Ill, 

 fig. 3 ; 112). An extensive sand beach has been formed near the northeast 

 point, by the disintegration of large blocks of limestone once a part of the 

 third terrace. A narrow shore platform, the first terrace consisting of 

 Nullipores, edges the reef platform near the north point (Pis. 111-113). 

 In the face of that terrace are seen caverns which are cutting out and 

 indicate the present sea level, just as those of the higher terraces indicate 

 former sea levels during the periodic elevation of Eua. Huge st.alactites 

 have dropped across the mouth of most of these caverns. On the west 

 side the terraces are somewhat indistinct (PI. Ill, fig. 1). The rounded 

 denuded tops of the lower terrace show in some cases very prominent 

 honeycombing, their surface being covered with small spires and crossed 

 by crevasses in all directions. Very few cocoanut trees were growing on 

 the island. South of the centre of the island, on the west side, there 

 is a deep gap in the terraces ; the slope runs uniformly to the highest 

 point of the island on the east side from the top to the fourth terrace. 

 Here and there are seen remnants of terraces five and six. Avith patches 

 of the characteristic red coral eaith standing out boldly in the centre 

 of the green slopes. Near English Roads there are extensive sand dunes 

 and the remnants of an old beach near the anchorage. 



The south point seen from the south shows distinctly all the terraces 

 from the lowest to the sixth ; towards the southern end of the eastern ridge 

 there is a small sharp pinnacle at the top of the sixth terrace, which 

 may possibly be the remnant of the seventh terrace. This small pin- 

 nacle is a prominent object in the topography of the island, and can be 

 seen from many points along the shore and from the interior. On the 

 western crest of the main drainage valley of the island (PI. 114, fig. 2), 

 facing the western slope of the eastern ridge, we see that terraces four to 

 six have been eroded, and that there is a uniform slope leading up to the 

 sixth terrace and to the top of the line of hills which forms the east face
