Wild pigs and deer continued plentiful, but the monkeys seemed gradually to disappear. Fish there were in plenty, but they were now of smaller kinds, not agreeable to eat, having an oily taste and mostly very bony. At all our camping places ants of various kinds were numerous, also inside of the tent, but they did not seem to be obnoxious. Just before sunset the loud voices of the cicadas began, and after dark lovely moths were attracted by my lamp, while during the night bats flew in and out of my tent. The humidity of the atmosphere was great. Safety matches would not strike fire unless kept in an airtight box. My cameras were inside of solid steel boxes, provided with rubber bands against the covers, making them water-tight. Nevertheless, upon opening one that had been closed for three weeks the camera inside was found to be white with mould. It was rough and hard travelling on account of incessant low kihams to be passed, or banks of small stones over which the prahus had to be dragged. The Penyahbongs had not yet learned to be good boatmen, often nearly upsetting the prahu when getting in or out. Occasionally long quiet pools occurred, and the scenery here was grand and thrilling. Graceful trees of infinite variety bent over the water, bearing orchids of various colours, while creepers hung down everywhere, all reflected in a calm surface which seldom is disturbed by the splashing of fish. The orchids were more numerous than I had ever seen before. A delicate yellow one, growing in spikes, had a most unusual aromatic fragrance, as if coming from another world. In the morning a curtain of fog lies over the landscape, but about nine o'clock it begins to lift, and creeping up over the tree-tops gradually dissolves in the sun-light, while between the trees that border the river the deep-blue sky appears, with beautiful small cumulus clouds suspended in the atmosphere. With the exception, perhaps, of a large blue kingfisher sitting in solitary state on a branch extending over the water, or a distant hornbill with its cheerful grandiose laugh, there are no evidences of animal life, nevertheless the exquisite scenery seems to lure the beholder on and on. To pass through this superb and silent realm was like a pleasant dream. There are no mosquitoes and consequently no malaria. We were progressing through a country of which little is known accurately beyond its somewhat hilly character, and the fact that it is uninhabited except for small transient parties of Malays searching for rattan or rubber. The upper part of our route to the divide, a comparatively short distance, had not, to my knowledge, been traversed by white men before. Errors were corrected on the map of the watershed region.
