This chapter examines the missions of the London Missionary Society (LMS) in Polynesia and Australia in order to explore the ways in which frontiers and boundaries between British and antipodean cultures were negotiated in colonial textuality. This chapter analyses the ways in which the boundaries between different orders of colonial thought about 'savage races', different kinds of colonial projects and political states, and different traditions of textual representation. The chapter focuses on both colonial intervention and missionary involvement. British missionaries were, however, extremely interested in representing encounters with both Polynesians and Aborigines. In Polynesia, missionary narratives of the frontier fed upon earlier visions of the Pacific region. The prominent LMS missionary William Ellis had visited Australia on his travels and written up his experiences there in his Polynesian Researches.
