In a book of this kind it is often the custom to begin by making apologies. In my case I feel it to be a sheer necessity. In the first place what is here printed is for the greater part copied word for word from private letters that I wrote in very simple language in Dayak or Negrito huts, or in the lonely depths of tropical forests, in the far-off islands of the Southern Seas. I purposely made my letters home as concise as possible, so that they could be easily read, and in consequence have left out much that might have been interesting.
