This travel narrative,written by a midshipman in the British navy on anti-slavery patrol in Brazil in the 1850s, gives an account of how ships suspected of belonging to slave traders were identified and boarded. Much of the narrative is based on the author's shore leave and his explorations of Brazil, but it is particularly interesting for his attempts to anticipate the pro- or anti-slavery bias of the reader and to mock and confound both in his descriptions of Brazilian slavery (see a satire of the "philanthropist" (48) and the "Americans of the pro-slavery class" (74)).
