equipment and reading. Off the S.W. end of Thithia at 2:30. Anchored off village at N.W. end at 3 P.M. in 9 fathoms. Good landing place. The island is mixed volcanic limestone. The interior hills which rise to an elevation of 540 feet are volcanic in origin, covered with the character- istic grass, scrub, Pandanus and Casuarina. At the S.W. are a chain of per- cipitous limestone hills covered with lowland forest, which stand behind the beach, out in front of the slope. They are fronted by a sand beach, and close in reef which is nearly fringing in places and just awash at half tide. The west side is low with lowland trees and groves of coconuts for a width of 1/4 to 1/2 mile, behind which rises the grassy slope. This is cut by small valley- like Lakenba. The ridge behind the two southern valleys on the west side is faced with lowland forest and may be underlain by limestone. Sandy beach. Sand flat to edge of reef. Roll 67:1. (1151) Limestone wooded cliff and grassy slope to south of and behind village of Tarukua, looking S.S.E. from anchorage. Developed two rolls films in evening with very good results. Monday, September 15. 1924. Thithia. (Around the island) Ashore at 6:45, landing at Tarukua. The village is moderately small, situated at the N.W. corner of the island. It is, however, the shipping point for copra for the rest of the island (except with very calm weather when Lomati may be shipped from), and several galvanized iron copra sheds front the beach. There is a Chinese store. The Buli of the island also lives here. Walked S. along a good trail down the west side. A high ridge of lime- stone formation rises from behind a moderately narrow beach flat covered with coconut palms and lowland trees. Tambuta is a well kept plantation belonging to the Borron Estate. Tall Bryophyllum plants in lowland field. Large fuscous cranefly in road. Also numerous cicindellids in road and not a few mosquitoes.
