to W.S.W. 25 feet wide, 5 to 15 feet deep, elevation 2890'. Ate lunch here, there being water in pools (not running), attempted to pick up the trail on the S. side, without success, and returned to camp. Sunday, May 4, 1924. The little thatched hut which I use as a base is in the midst of an extensive taro patch, situated on a bench on the N.N.W. slope of a ridge running from the high hill mentioned yesterday to Safotu. Nearby are two varieties of sugar cane, mango trees, breadfruit trees, semi-wild pineapples, papaia trees, pumpkin vine, and bananas. The taro has the usual black leaf- hoppers, and an orange and fuscus small bug. A large brown Dacus (?) Trypetid fly attacks the papayas. There is also a large yellow-brown beetle on the pumpkin vine. A small dark Anthribid beetle is to be found on the papaya trunks and quantities of yellow-brown Drosophilid flies about the decaying fruit which has been bird or rat eaten. The thatch of the house is full of Odynems and blue black wasps. Two species of gray muscids are abundant and troublesome, one being Musca vacina (the "narrow fronted domesticus") and the other the common Pacific species found on Nihoa, Laysan, Wake, etc. with broad bands on the abdomen. Up the trail to a point where it turns S.R. up the ridge. Then across country, keeping on E. course by compass, through the thickets and vine covered open spaces, and coming out at the 1905 crater. Up a gradual slope to 1850 and then practically level. The thick vine and (last half mile) breast high young tree ferns, made walking difficult and tiring. As one approached the lava flow, down the last slope, the trees become fewer, with many of them dead, very little undergrowth excepting young tree ferns and the ever present vine, and underfoot the crunch of cinders beneath the vine. The edge of the lava is fairly well defined, but the vine runs out over it for 25 yards or so. The lava is very brittle, much of it smooth but with large areas especially
