The wild tribes of BORNEO, and the not less wild interior of the country, are scarcely known to European readers, as no one who has travelled in the Island during the last fourteen years has given his impressions to the public. My official position afforded me many facilities for gratifying my fondness for exploring new countries, and traversing more of the north of Borneo than any previous traveller, besides enabling me to gain more intimate and varied experience of the inhabitants. In the following pages I have treated of the tribes in groups, and have endeavoured to give an individual interest to each; while, to preserve the freshness of my first impressions, I have copied my journal written at the time, only correcting such errors as are inseparable from first observations, and comparing them with the result of subsequent experience. Preserving the natural order of travel, I commence with an account of my expeditions among the tribes living in the neighbourhood of Sarawak; then follow narratives of two ascents of the great mountain of Kina Balu, the loftiest mountain of insular Asia, of which I have given a full account, as it is a part of Borneo but little known, and rendered still more curious by the traces we find of former Chinese intercourse with this part of the island; my personal narrative being concluded by the journal of a distant expedition I made to explore the interior of the country lying to the south and south-east of Brunei, the capital of Borneo Proper. The starting-point of the first journeys was Kuching, the capital of Sarawak, where I was stationed in the acting appointment of H. M.’s Commissioner in Borneo. I lived so many years among the Dayaks, that the information I give of their mode of life may be relied on; and I have received so much assistance from others better acquainted with individual tribes, that I can place before the public, with great confidence in the correctness of detail, the chapters on the Manners and Customs of these people. I persuade myself that the more the natives of Borneo are studied, the more lively will be the interest felt in them. The energy displayed by the Sea Dayaks, gives much hope of their advancement in civilization at a future time; and a few years of quiet and steady government would produce a great change in their condition. The Land Dayaks scarcely display the same aptitude for improvement, but patience may do much with them also; their modes of thought, their customs, and the traces of Hinduism in their religion, render them a very singular and interesting people. Of the Kayans we know less; and I have only been able to give an account of one journey I made among them, very slightly corrected by subsequent experience. They are a strange, warlike race, who are destined greatly to influence the surrounding tribes. They have already penetrated to within thirty miles of Brunei, the capital, spreading desolation in their path.
