"But I was destined to grow up away from the house of my parents. Immediately after my birth I was wrapped in the finest soft tapa cloth, and taken to the house of another chief, by whom I was adopted... This was, and indeed is, in accordance with Hawaiian customs. It is not easy to explain its origin to those alien to our national life, but it seems perfectly natural to us. As intelligible a reason as can be given is that this alliance by adoption cemented the ties of friendship between the chiefs. It spread to the common people, and it has doubtless fostered a community of interest and harmony"
