# IV explained — The Innocents Abroad > Chapter companion for The Innocents Abroad by Mark Twain. ## What happens The pilgrims become accustomed to shipboard life, engaging in various amusements such as horse billiards, writing journals, mock trials, charades, and dancing. The chapter humorously observes the passengers' initial enthusiasm for journal-keeping and its inevitable decline, as well as the social and religious routines aboard the Quaker City. ## Themes in this chapter ### Travel as Education The pilgrims' journal-keeping reflects the expectation that travel should be educational and documented, though the reality often falls short. ### Satire of Tourism The chapter humorously critiques the pilgrims' superficial engagement with travel, such as Jack's abandoned journal and the mock trials. ## Character check-ins ### The Narrator Describes the daily routines and amusements of the pilgrims, including the journal-keeping phenomenon. ### Jack A young pilgrim who enthusiastically starts a journal but soon abandons it, finding the task tedious. ### The Doctor Mentioned indirectly as part of the group; not a central figure in this chapter. ### The Captain Referenced in the context of ship timekeeping and navigation. ## Key lines > We plowed along bravely for a week or more, and without any conflict of jurisdiction among the captains worth mentioning.
