is a large pool of brackish water. The natives visit the upper part of the cave, as there was the remains of a fire near the entrance. Many of the trees are festooned with the codate leafed climbing vine with large white flowers and spherical brown capsuls. Collected the fragrant white flowers of thē small tree on rocky slopes which has 4 ribs and contains a bright orange pulp in which are inbedded numerous small cream colored seeds. Several fruit were broken open and the contents partly gone as if eaten by birds. (Nos. 399 and 529). Collected about the eastern end of the island, obtaining a very few land- shells and quite a number of small insects principally by heating the leaves of shrubs and small trees. Saw a large skipper, the same species, (I think) as captured on some of the other islands. Very few large or conspicuous insects on the Aiwa islands, except some betterflies and moths, which were seen principally in the grass or about the weeds near the sand beach and coconut clump. Saw practically no new plants on this island. The large olive-green lizards are quite abundant but hard to catch. Mr. Beck shot several and also one of the very large green lizards. The small green tailed skink (called "pili" by the Samoans) is abundant. Also one oc- casionally scares out a gecko (called mo'o or moko) from its hiding place in a hollow tree, under bulging bark or beneath a log. Along the trail between the sand beach and the clump of coconuts and spreading out along the extreme east end of the island is an area of introduced weeds and grass, especially the yellow flowered composite. Among them (and seen no where else on the island) is the pepper (Capsicum frutescens) which forms with Piper the dominant forest undergrowth on some of the other islands. I had considered it indigenous, but this tends to show that it has been introduced during the period of man's presence, as it seems to be only where he has been, which may also be true of the Piper. The latter is not
