lowlying islands are forested. Wonder if sandstone and basalt are not more porus, allowing the moisture to sink to the water table, while the limestone, being more impervious holds the moisture, allowing a more luxurious vegeta- tion. Further, the limestone islands have no springs and very few streams, while these abound on both volcanic and sandstone islands. The vegetation on the sandstone "bare knobs" consists principally of Pandanus, Casuarina, stunted "rowa", small shrubs of the tree with yellow flowers and white floral leaves, guava bushes, stunted moni and ti, grass, weeds, and occasional planted trees such as orange, mango and coconut. Followed a fiar trail eastward beyond Dakulou to the east end of the island. Beyond the village the country is underlain with limestone and is moister, rougher and covered with a more luxurient vegetation. There are two ridges trending N.N.E. and S.S.W. separated by a small valley filled with coconut palms and cleared garden patches. The eastern ridge is nearly bare of trees, and has either been cleared for the gardens or is too dry. Beyond this ridge a narrow neck of low land runs out to a steep conical peak about 120 ± feet high. Sand beach along part of the south side back by the usual beach trees. Toward the east end of the south side and on all the north side the beach is edged with a flat topped wall of conglomerate - dark gray volcanic (?) rocks and limestone cemented together with sandstone. (See samples). The small islet, Loa, is about 3/4 mile to the W.N.W. It is a small truncated cone-shaped islet, the south slope steep and bare of trees, except a few Casuarinas, a small knot of beach trees on the north side and a sand beach covered with coconut palms on N.W. Patches of reef between it and the east point of Oneata. The green spiny-legged grasshopper on the leaves of Scaevola and Tourne- fortia. Collected some pods of Erythina indica. The dry pods were full of small pale ants with fuscous heads, large fuscous ants, flat shiny black
