The negroes in Lima number not far from 10,000 of whom less than half are slaves. The charter of Independence provides that no person in Peru shall be born a slave, but this provision has been modified by law, so as to allow a term of servitude varying from 25 to 50 years. Slaves brought from any other country, become free the moment they touch the soil of Peru. Hence if a master take his slave into Chili, the slave may claim his freedom on his return. Runaways, however, are liable to be reclaimed. The treatment of slaves in Lima is very gentle. A tribunal is erected having the special duty to protect the slaves from ill-treatment. A slave may claim his liberty upon paying his value; and in case he and his master are unable to agree upon the sum, it is fixed by the court; or he may sell himself to any other master who will pay the determined price, in spite of any opposition on the part of the owner. As the introduction of negroes from Africa has been for many years prohibited, the great majority of the slaves are born in Peru. These, though intellectually and physically superior to those born in Africa, are held of less value; their superior intelligence rendering them less docile, and more discontented with their condition. The free negroes of Lima are represented as a plague and a pest to society. As a general rule the mixed races, which constitute about a third of the population of Lima, inherit the vices without the virtues of the pure races from which they sprung. Perhaps the sole exceptions to this are the _Mestizos_, the offspring of a white father and an Indian mother. They are of mild and gentle dispositions, but are also timid and irresolute. There are few Mestizos in Lima; but in the interior they are numerous. There they constitute the entire population of many villages, and call themselves whites, keeping aloof from the Indians. The most prominent characteristic of the Mulattos, the offspring of a white and a negro, is their remarkable imitative talent, and their consequent aptitude for mechanical pursuits; but they are extremely sensual and animal in all their tastes and instincts. The _Zambos_, sprung from an intermixture of the different castes of the colored race, and the _Chinos_, the offspring of the colored and Indian races intermixed in various degrees, are the most miserable and degraded of all the half-castes in Lima. They commit the most inhuman barbarities with the utmost indifference. Four-fifths of the prisoners in Lima are Zambos. They are usually athletic and muscular, with sunken eyes, thick lips, and noses much less depressed than that of the negro. The Chinos are morally about on a level with the Zambos; but physically they are much inferior. The mixed races of fairer complexion resemble the whites in moral and intellectual qualities in about the same degree that they approach them in color.
