The author narrates his experiences during several years in Spain and Portugal while acting on behalf of a Bible society, describing journeys to towns and the countryside, efforts to print and circulate the Scriptures, confrontations with civil and ecclesiastical authorities, brief imprisonments, and frequent encounters with peasants, muleteers, and local clergy. The account blends practical missionary activity with vivid language learning, travel anecdotes, cultural observation, and reflective commentary on religion, social customs, and national character.
