even the shovel marks are still visible; indicating absence of erosion. Sea birds exceedingly abundant, great colonies of terns, frigatesand boobies dotting the green plane. Rats and lizards also abundant. Spent evening trying to collect moths from kou, ipomoea and tournefortia by flashlight. Not abundant. Camped near landing, S. side of low hill. Wednesday, March 19, 1924. Away from camp early and south to grove of Tournefortia trees:- usual white, red and black spotted moths, yellow flies, and spiders; and on Sida and Borehaavia bushes nearby: white micros, red ants, black thrips, and small white and brown moths. Green muscid attracted to excrement. The Tournefortia patch is wedge-shaped, 200-250 yards long on east, 100-150 on west, and the N. arm, extending N.E. about 200 yards. The S. end is opposite the N. end of the lagoon on W. side. There is a single small kou tree in front. Between this grove and the lagoon (going S.E.) is a patch of white flowered Ipomoea vine and some low bunch grass, harboring a large colony of sooty terns, so numerous as to form a black cloud when they rise. The margin of the lagoon and numerous low, flat sandy islands in it are covered with Sesuvium. The lagoon is small, and shallow, less than 1/2 mile long and 300-350 yards wide at the widest place. Opposite the S. end of the lagoon, on the W. side and about 400 yards south of the grove of trees are the ruined slab walls of seven small houses averaging 12 x 15 feet, the walls are nearly 6 feet high and a large double conal-like enclosure, 40 feet square with walls 4 feet high. On top of the front one, which is filled in solidly with rock, rests a small rusted iron cannon about 3 1/2 feet long, whose original bore was perhaps 2 1/2-3 inches, now much corroded. Two of the houses rest on a small paved (paepae-like) platform. The house in front is 60-75 yards from the beach, the others more. About 400 yards south and 150 yards from the beach is an isolated, stunted kou tree, much eaten by the large mottled caterpillar. On it are
