Before setting out on the first of these voyages, the author had contracted to write an account of his adventures in the form of letters for serial publication. The plan by and by changed in his mind into that of a book partly of travel and partly of research, which should combine the results of much careful observation and enquiry upon matters of island history, custom, belief, and tradition, with some account of his own experiences and those of his travelling companions. Under the nominal title of ‘Letters’ he began to compose the chapters of such a book on board the ‘Janet Nicoll,’ and continued the task during the first ten months of his residence in Samoa (October 1890 to July 1891). Before the serial publication had gone very far, he realised that the personal and impersonal elements in his work were not very successfully combined, nor in proportions that contented his readers.
