The city abounds in beautifully arranged squares, ornamented by that king of the tropical forest, the Royal Palm, with here and there a few orange trees, surrounded by a luxuriant hedge of limes. The largest and most beautiful of these squares is the _Plaza de Armas_, fronting which is the Governor's palace, and about which are the massive stone barracks of the Spanish army. This square is surrounded by an iron railing and divided into beautiful walks, planted on either side with gaudy flowers, and shadowed by oranges and palms, while a grateful air of coolness is diffused around by the playing of a copious fountain into a large stone basin, surmounted by a marble statue of Ferdinand. Public squares, parks and gardens, are the lungs of great cities, and their value increases as the population becomes dense. Heap story upon story of costly marble, multiply magazines and palaces, yet neglect to provide, in their midst, some glimpse of nature, some opening for the light and air of heaven, and the costliest and most sumptuous of cities would prove but a dreary dwelling-place. The eye wearies, in time, of the glories of art, but of the gifts of nature never, and in public squares and gardens both may be happily combined. Human culture brings trees, shrubs and flowers to their fullest development, fosters and keeps green the emerald sward, and brings the bright leaping waters into the midst of the graces of nature. Nowhere does a beautiful statue look more beautiful than when erected in a framework of deep foliage. These public squares are the most attractive features of cities. Take from London Hyde Park, from Paris the Champs Elysées and the Tuilleries gardens, the Battery and the Park from New York, and the Common from Boston, and they would be but weary wildernesses of brick, stone and mortar. The enlightened corporation that bestows on a young city the gift of a great park, to be enjoyed in common forever, does more for posterity than if it raised the most sumptuous columns and palaces for public use or display.
