method apparently. Mauga silisili is undoubtedly the highest. It is called "Papafu" locally (about Salailua). Monday, May 19, 1924. Ankles badly infected and walking painful. Ashore at 7 A.M. and up trail to spring. Collected very little on way up because of wet foliage. Elevation of spring 1100', distance about 3 miles. Brown crickets with narrow white abdominal bands common. Small black flies and red-brown Drosophila flies abundant. Collected quite a number of plants on return trip, mostly ferns. Called on Mr. Stahlin, trader and representative of Nelson, and obtained permission to explore caves on his property. They are lava tubes. Caught 4 brown butterflies of a number hovering about a Tournefortia tree on the beach, the first seen on Savaii. Snakes called gata. "Darning needles" - Odonata - semu. Dragonflies - mataga. Tuesday, May 20, 1924. Spent early morning doctoring ankles. Ashore with Mr. Beck at about 9:30 equipped to explore the lava tube caves. They consist of a network of lava tubes opening by several low entrances upon the face of the cliff which forms the beach referred to before. At the point where the tube emerges, the cliff is about 60 feet high and 150 yards from the beach.. Crawled and walked about three branches, catchin[illegible] 21 bats (pe'a) and a young swift. In afternoon walked down past Siutu in direction of Lataitai a mile or so. Then N.E. across country through a moist lower forest to another trail which followed back to Siutu. Had tea and a most enlightening conversation with a trader, Mr. Davidson, who leases the Latai district, raises copra and carries on a successful trading business with two stores.
