“About the mouth of the little stream that we had just crossed were numerous shallows and bars, which were covered by the acre with ducks, geese, huge white-breasted cranes, and long-beaked pelicans, while the solitary albatross, or sea-gull, circled above our heads with a saucy look that drew many a random shot, and cost one, at least, its life.”
