Leaving the modern Paseo Colón and Exposition Park, and crossing the Rimac, one is again in the old city of the viceroys, the famous Avenida de Acho extending along the river bank from the ancient stone bridge, built in colonial days, to the modern structure called the Balta Bridge, in honor of a former president of the republic. This avenue, the fashionable promenade of the capital up to half a century ago, is divided into three roadways, the central one, bordered with tall poplars, being used for riding and driving, while those on each side are reserved as walks. It is popular on holidays and is thronged on the days of the bull fights. Of equal interest, historically, is the _Jardin de los Descalzos_ (“Garden of the Barefooted Friars”), which is situated a short distance beyond the Avenida de Acho, and just at the foot of the Cerro de San Cristobal, a mountain that rises close behind the city. The garden of the Descalzos extends along an avenue more than half a mile in length, ornamented by twelve statues that represent the signs of the zodiac, and it is beautified throughout its length by tropical trees and plants, while at intervals are placed handsome urns and marble benches. An iron railing, six feet high, surrounds the garden, and a beautiful fountain at its terminus completes the harmony of the picture, which is enhanced by the overshadowing Cerro, and the ancient church and convent of Barefooted Friars, just below. [Illustration: KIOSK OF PALMS, EXPOSITION PARK.] With the destruction, a few years ago, of the walls that formerly surrounded the city, plans for its beautification were initiated on an extensive scale; the Boulevard Bolognesi, the Boulevard Grau and other broad _paseos_ were laid out, forming an almost uninterrupted driveway from the river around the city’s southern limits to the river again. The Boulevard Grau passes the Botanical Garden, in which are collected specimens of tropical and semi-tropical flora of every variety. Stately palms guard the entrance to the garden, and bordering its shady walks are beautiful plants and flowers in gorgeous colors and of wonderful growth. The _Chusia_, a remarkable tree of which the fruit bursts open when ripe, showing a pretty flower with scarlet seeds, is among the interesting arboreal specimens seen here.
