“ The third zone loses its arid character as it approaches the coast, and is better clothed with vegetation. The coastal plain varies in width and character: in some places low and sandy, or swampy, filled with lagoons and intersecting canals; in others more elevated, rolling and very fertile. The climate corresponds closely to these surface features, being hot and dry throughout the interior, hot and humid, in places unhealthy, along the coast. ”
