502. Gardens at Madrid. Most of the grandees and wealthy merchants in the city have symmetrical pleasure-grounds, with greenhouses for keeping the tender plants during winter. Among the most remarkable of these gardens may be mentioned the Alameda, which is embellished with fountains, basins, cascades, canals, statues, temples, &c. The Buen Retiro is, however, perhaps the most remarkable garden within the walls of the city, as it contains a menagerie. The public enjoy the privilege of walking in part of these gardens, which are several acres in extent, though the other part is reserved exclusively for the recreation of the royal family.
