The plaza in Cienfuegos is the largest on the island. It is kept in order by the coolies--a race of people brought from the mountains of Asia, which forms the most numerous servile population in the country. At night it is the scene of a grand display, or military parade. The band comes from the barracks, surrounded by a military escort, near which no one is permitted to pass. The guards are all extremely tall, dark, well-formed men, being of Moorish origin. While on duty they stand as mute and motionless as statuary, with their guns pointing upward, but ready for instant action at the word of command. It is here the chill winds never come, and drape the foliage in somber hues--the flowers are always blooming, sweet as dreams borne on angels' wings. To this plaza, at night, the entire population of the city resort for recreation, and to breathe the fresh air. The grounds are divided into parterres, laid out at right angles, through which are wide avenues, paved with flat rocks. In the center is a fountain and grotto, near which are four marble statues representing the seasons. No fabled habitation of the genii, or enchanting description of the Isle of Calypso, could fill the imagination with more delightful emotions than the real scene before us. The bright moonbeams come stealing softly through the scarlet hibiscus, and feathery palms wave their graceful wands above our heads, while the most gentle zephyrs fan our brows with their blandest breeze, and every thing seems tipped with silver sheen, and too unreal for earth. The gay and beautiful señoritas soon commence promenading, many of them dressed in white, with long, starched trains to their robes, and skirts that swept over the paved boulevards with a rushing sound, like the waves plashing against a vessel, although the accompaniment of shuffling sandals and slip-shod slippers of the men make a grinding noise nothing suggestive of grace or elegance. The music soon struck up, with its most fascinating strains; everybody seemed to partake of its harmonious cadence, and commenced moving about with the grace of sylphs. The soldiers and police, with their _brusquiere_ movements, were the only ones present not given up to the most perfect _abandon_ for enjoyment. Among other choice and beautiful pieces, the band played _Il Trovatore_. The melody seemed intensified by the same pathos that seized the mind of the great composer when he wrote it; and as its sounds died away among the moonbeams and perennial foliage, while its echoes lingered in the air, the surroundings appeared too beautiful for any thing but the culmination of all on earth that might be termed grand.
