EASTER ISLAND. 55 



katiki. Somewhat more to the westward is the rounded hill formino- 



o 



Rosalie Point, the outer slope of which has been weathered (PI. 17) to form 

 a small landing place in Ovahe Bay (PI. 18, fig. 3). To the west of La Pe- 

 rouse Bay are irregular bluffs on the shore slope of the saddle separatin"- 

 La Perouse Bay from Anakena Buy (PI. IG, fig. 1). 



One of the many amphitheatres of the north shore is formed by the 

 falling in of the volcanic tufa bluffs at the foot of Blossom Ilange to the 

 west of Anakena Bay. Skirting the west coast, somewhat south of North 

 Cape, we see the range of isolated rounded domes extending from Kotatake 

 (Mount Powell) in a southeasterly direction towards Mounts Palmer and 

 Orito (PI. 20, fig. 1). Mount Beechey is seen in the distance to the left. 



From our anchorage in Cook Bay an excellent view is obtained of the 

 western and northern slope of Rana Kao, with the steep bluff of the western 

 rim of Rana Kao at Orongo forming the southwesterly extremity (Karikari 

 Point) of Easter Island (PI. 20, fig. 3). 



Rana Roroka is a small, low volcanic cone rising gently from the level 

 of the great plain to the south of La Perouse Bay, in the rear of Tongariki, 

 Hanga Nui Bay (PI. 13). Seen from the west (PI. 26, fig. /) the rim of the 

 crater is somewhat lower on that side, giving access to the crater through 

 a gap on the southwest side of the rim. The eastern rim is a good deal 

 higher than the western, and has a deep gap separating the noitliern 

 from the southern part of the rim of the crater (PI. 26, fig. ..'). The south- 

 eastern face is quite steep, with a talus reaching nearly half-way towards 

 the gap on that side of the crater. 



The low northern rim of the crater of Rana Roroka (Pis. 18, fig. /; 25), 

 has a very moderate slope. The crater is filled by a large pool, the edges of 

 which are overgrown with reeds and bulrushes. It is more open than the 

 pool of the crater of Rana Kao, which is carpeted by a nearly solid ])ed of 

 moss, reeds, and bulrushes, strong enough to allow cattle to walk over the 

 greater part of the carpet of vegetation and to reach the small open pools 

 of water scattered on its surface (Pis. 23, 24). 



The highest point of Rana Roroka is not more than about 630 feet. The 

 pass into the crater, but little above the level of the water in the crater, is 

 about two-thirds that height. The slope of the crater is quite gentle. 



Rana Kao is more than twice as high, 1327 feet. The path leading to 

 the bottom of the crater (the level of the lake) is ver}^ steep. The lake is 

 fully 700 feet below the highest point of Rana Kao, and is about a mile in
