The author records a traveler's observations of an Atlantic archipelago, combining vivid landscape descriptions, townscapes, and everyday life with historical and economic notes. Early sections contrast volcanic peaks, deep barrancos, and terraced slopes with dusty ports, old patios, and narrow streets, often enlivened by local costumes and markets. Accounts of flora, gardens, and practical travel details sit alongside explanations of industries such as cochineal cultivation and its subsequent decline. The text mixes personal impressions, botanical and historical digressions, and practical advice, and is accompanied by numerous color illustrations and a sketch map.
