I was desirous of having Chonggat remain here for a week of collecting, but no Kenyah was willing to stay with him, all being deterred through fear of Punan head-hunters, who, on this river, not so long ago, had killed some rubber-gatherers from Sarawak. Besides, they also anticipated revenge on the part of Kayans, eleven of whom had been killed by the Kenyahs in Apo Kayan one and a half years previously. According to their own reports and that of the Chinese interpreter, the heads of six men and five women had been taken after a successful attack on the two prahus in which the Kayans (Oma-Lakan) travelled. The Kenyahs (Oma-Kulit) who had committed the outrage had been apprehended by the Company, as the government is called by the natives. The brother of the chief of Long Pelaban, who was with us fishing, three months previously had returned from Samarinda, where he had spent one year in prison for having been implicated in a minor way in this crime, while the main offenders were serving labor terms of six years in Sorabaia, Java. This report was confirmed by a Dutch officer whom I met a month later and who came from Apo Kayan. The attacking Kenyahs were eighty in number, of whom ten were punished. The affair took place in 1912 at a distance of six hours, going down-stream, from Long Nawang. Though head-hunters are known to travel wide and far, and distant Apo Kayan is not too remote for them, nevertheless to me, as well as to Chonggat, the risks seemed unfounded; however, there remained no alternative but for all of us to return to Long Pelaban. CHAPTER X IN FOG AND DARKNESS--A RAID BY ANTS--DEPARTURE FROM LONG PELABAN--AN EXCITING PASSAGE--RETURN TO TANDJONG SELOR During April and the first half of May the weather was warm with very little rain, though at times thunder was heard at a distance. But during the second half of May thunder and lightning in the evening was the usual occurrence, with an occasional thunder-clap at close quarters. At night it rained continually though not heavily, but this was accompanied by a dense fog which did not clear away until nine o'clock in the morning. When the dark clouds gathered about sunset, it was not with exactly cheerful feelings that I anticipated the coming night. My tent stood at a little distance from the rest of the camp, for the reason that solitude at times has its charms. When the lamp outside the tent door was extinguished, and all was enveloped in darkness and fog to an overwhelming degree, a feeling of loneliness and desolation stole over me, though it soon left me when I thought of the glories of the coming day, when all the rain would be forgotten.
