155 Umi River Botanized up the river again. Interesting plants a common red Mucuna, glabrous, and otherwise different from the common species now flowering at Arnu and Kassam; a Cananga not so sweet scented as most, and a Laportea, common here, with stinging hairs only on the margins of the big leaves and on the inflorescences. There is perhaps more moss in this forest than at Kassam, indicating a climate rather constantly wet. Only mammal on the table today was a Phalanger orientalis shot last night by Van. Traplines changed today to the tongue of hills between the two branches of the river. A small muddy pond some half mile up the river from camp, secluded in the forest and surrounded by Polygonum beds, is the best place for dragonflies and damselflies I have found on the trip. Collected there today 6 spp. of the former, 7 of the latter and saw four more of dragonflies which I could not get near. Tuesday, November 17. The heat continues -- 92 F. today. Sunny and SE wind most of day. Some rain during last night. Much thunder in late afternoon and early evening. Walked to the swing bridge over the N branch of the Umi (a mile or better) and from there followed a patrol track perhaps 1/3rd mile up the far bank first through low second growths then through rain forest as good as any seen here. My biggest day for plants in some time -- about 30 spp. Good male and female material of three Macaranga spp., a number of ferns and undergrowth plants in- cluding two of the Marantaceae. A small fan-palm like an Oomsis species is fairly common on the river flats in forest undergrowth; two Calamus spp. noted, both sterile. The price offered for wallabies has had its effect - or the beginning of it. Hunters returning from the hills upstream late in the afternoon brought three Dorcopsis (heaviest 14 lbs.), one Phalanger gymnotis, one P. orientalis, one Peroryctes raffrayanus and one Echymipera kalabu, plus a green goanna and a green python. Shot at the north bridge this evening (a good place for bats at dusk) was a bat of the Hipposideros-Miniopteris group which Van can not place on sight. Not a thing in traps. But shot last night by John up the creek were Uromys caudi- maculatus, Melomys and a Rattus. Wednesday, November 18. 91 F. at 2 p.m. Heavy rain from a thunderstorm began soon after 4 and continued at least an hour. River rose 2 ft. or more. Our resthouse roof leaked badly and we had to cover up everything and sit in the dry spots. Light rain still falling at 10 p.m. Worked into the hills up a trail to the WSW originally cut for mammal trapping and jacking. Ground rose in three terraces above the one we are camped on, then about 150 ft. more up a fairly steep spur ridge to a total of perhaps 700-800 ft. above camp. Forest above the first terrace contains some very big, buttressed trees few of the tops of which could be seen from the ground, but it was an exceptionally poor forest in the lower layers with practically nothing to be collected.
