and coconut groves. On the north are two wooded limestone ridges, located at the N.W. and N.E. corners. The west slope is volcanic, backed on the south by a high limestone ridge which continues around the south side and ends in a high flat topped peak with precipitous S., N. and E. slopes. Ashore at 11:15 and met Mr. G. M. Henning, the owner, and his wife. They have a very attractive homestead on the west side. Anchorage possible off the coral heads on the west side, when the wind is off shore. Several tracks lead over the ridge and traverse the central basin, in which is situated the bulk of the coconut plantation. There are low places in the enclosing wall on the N. and S.E. The basin is underlain by both volcanic and limestone rock, if one is to judge by the outcrops, the latter perhaps predominating, with very good soil. There are numerous patches of lowland forest within the basin between the groves of palms, and more dense growth on the slopes. In places additional clearing is in progress and great numbers of young coconut palms have been set out. Caught a few beetles and some small pseudoscorpions in the dead leaves. Butterflies very abundant especially about the fields of milk weed. Monarchs, the small red brown and fuscous species, H. bolina with both yellow and dull colored females, swallow-tails, yellow sp. orange sp., Lycaenid blues, black and white, "dead leaf", etc. A few small moths, small and large orthoptera, flies, etc. Quite a number of Casuarina trees:- in rows in the basin and patches on the S.W. rim. From the S.E. side could see Malima islands - low with sand beaches. Roll 71:5 The high flat topped peak, looking S. by W. through the (11579) coconuts. This flat topped peak rises perpendicularly for its upper 1/3 (200'\frac{1}{2}) on three sides, sloping down in a ridge on the W. It looks like a shaft of limestone, but samples taken from the foot of the cliff have the appearance of basalt. At the spot where the samples were taken, (on the south side) the
