The only sign of commercial activity within the harbour, visible from the beach of the Great Isabel, is the square blunt end of the wooden jetty which the Oceanic Steam Navigation Company (the O.S.N. of familiar speech) had thrown over the shallow part of the bay soon after they had resolved to make of Sulaco one of their ports of call for the Republic of Costaguana. The State possesses several harbours on its long seaboard, but except Cayta, an important place, all are either small and inconvenient inlets in an iron-bound coast—like Esmeralda, for instance, sixty miles to the south—or else mere open roadsteads exposed to the winds and fretted by the surf.
