Found a small hut on the north beach. Returned to the schooner at 11:45 and underway immediately for Olorua, which we reached at 2:30. [Chart on Page 45]. Roll 63:4. Olorua from the N.W. with Komo beyond. (11533) Olorua is of volcanic origin, rising steeply from the water to a height of 250 feet in three humps, which form a triangle. On the south side of the northern peak is a conspicuous clump of Casuarina trees, standing up against the skyline. Other clumps of this species dot the sides, especially the west side. The east, north and south slopes are rounded and wooded with scrub and fair sized trees. The N.W. and S.W. ends drop percipitously to the narrow beach. Each side of the central low dip is occupied by groves of tall coconut palms. Landed at 3 P.M. on the N. end; the ship anchoring about a quarter or third of a mile off the land here in 12 fathoms, a hundred yards or so off the reef. Most of the N. and east beach is made up of volcanic boulders and pebbles of various sizes up to 2 feet. The slopes vegetation includes Casuarina,puapua Hernandia peltata, Pandanus rewa milo, and other lowland trees. These form an open, park-like stand with volcanic pebbles and patches of dry grass (No. 519 and 520) beneath. A small stream trickles down the slope of the low place through the coconut grove. The ironwood trees on this slope attain a larger size than any I have seen in Lau, being up to 2" in diameter and 20' high. Found a very interesting bedding of a sandstone-like material olive brown to dark brown layers. The layers of the N.W. face south peak dip slightly to the south west. On the S.W. face it dips to the S.E. at an angle of 25° or 30°. Between are various intermediate inclinations. On the N.W. face of the N. peak it dips to the N.N.E. at an angle of about 20° or 25°.
