Of the Miranhas we are told that they enslave their prisoners; but usually these prisoners are intended to be sold to the whites. It does not appear whether any of them are kept for the Miranhas’ own use[157].

Keane, von Tschudi and Ehrenreich make no mention of slavery among the Botocudos. According to Zu Wied “the conqueror persecutes the vanquished, and but seldom makes captives, at least among the Botocudos; but on the Belmonte there are said to be seen some who were used as slaves for all kinds of work”[158]. We do not know what this last second-hand information of Zu Wied’s is worth; but we are justified [[75]]in inferring that the Botocudos in general (except those on Rio Belmonte) have no slaves.

Azara states that in his time (he travelled in South America from 1781 to 1801) the Guaycurû had nearly died out, only one man being left[159]. But according to Boggiani Guaycurû is a general name for the tribes that inhabit the Gran Chaco[160], so this statement of Azara’s seems to apply to a small division of the Guaycurû only. Southey and Martius give some particulars about the slave system of the Guaycurû[161]; but Colini, who has taken great pains to ascertain the identity of these tribes, quotes these descriptions as referring to the Mbayás. Of the ancient Guaycurû he says: “In their combats they gave no quarter to the adult males; but they spared the lives of the youths, whom they educated after their customs and gave in marriage to their daughters, so as to augment the number of their tribe. Full-grown women were sold to the neighbouring nations, who made them slaves”[162]. The only captives whom they kept among them, the youths, were not slaves; so slavery probably did not exist among them.

Two tribes inhabiting the Gran Chaco and so belonging to the Guaycurû in Boggiani’s sense, are described by Thouar. Of the Chiriguanos he says: “The prisoners are the property of their captors and must serve the mistress of the hut.” In his description of the Tobas he makes no mention of slavery[163]. Thouar, however, does not seem to be very well informed[164].

The Mbayás, according to Azara, in his time had two kinds of slaves, one composed of the Guanás, the other of Indian and Spanish prisoners of war. But the former were no real slave class. The Guanás “used to repair in troops to the Mbayás, to obey and serve them and till their lands without any payment. Hence the Mbayás always call them their slaves. This slavery is indeed very mild, as the Guaná voluntarily submits to it, and leaves off whenever he likes.” Such “slaves”, who lead a tribal life and come and go when they like, certainly are not slaves. The others however were real slaves. They procured the fuel, cooked the food, took care of the horses [[76]]and tilled the land. When Azara once offered a present to a Mbayá, the latter would not take it himself, but ordered his slaves to receive it for him. Even the poorest Mbayá had three of four slaves. During the mourning-time women and slaves were not allowed to speak or eat any meat. One place in Azara’s book seems to show that they had no slaves: “They said they had received a divine command to wage war against all nations, kill the adult males and adopt the women and children, in order to augment their number.” But where the recorded tradition and the description of the actual state of things disagree, we hold that the latter is to be accepted[165]. Colini refers to Azara and Martius, and then adds: “Serra however asserts that among the Mbayás slavery proper (la schiavitù vera e propria) did not exist; the slaves might rather be called servants.” They fought together with the freemen and took part in the public council, even when it decided upon war and peace. They married free persons, but were themselves looked upon as slaves. On the master’s death, the sons or next relations, according to the rules of inheritance, became masters of the slaves; but these rights were only nominal. The slaves gradually merged into the tribe. Yet it was always considered degrading to be a descendant of a slave; those who had in their ancestry none but members of the tribe were very proud of it. Generally the best slave girls were married to their masters; the boys of greatest promise were treated as sons, whereas the others were set to do the ruder work[166]. This account, however, does not prove that the captives were not slaves. Some of the boys only were treated as sons; what were the rest if not slaves? And even slaves may to a certain degree be treated as sons. The slaves gradually coalesced with the tribe (though not entirely); but we are told that this change took place “through personal merits and intermarriage.” This shows that all captives were not on a level with the freemen; probably it was only the most deserving prisoners, and the offspring of slaves and freemen, who attended the public council and were on an equal footing with the main body of tribesmen. Slaves may be kindly treated and yet be slaves. [[77]]Our opinion is, that we have here a schiavitù vera e propria; the more so, as the description given by Azara leads to the same conclusion.

The present Caduvei, according to Boggiani, are the same people as the ancient Mbayás. Very probably he is right here. Yet we have seen how much confusion there is in the application of the terms Guaycurû and Mbayás; so we are a little sceptical. Moreover, there is a great lapse of time between the early descriptions of the Mbayás and Boggiani’s travels, and during that time their state of culture has greatly changed; from nomadic hunters they have in the 19th century become settled agriculturists[167]. So we are justified in treating them separately. The Caduvei keep slaves. The slaves are well treated, but looked upon as an inferior race. The ruder kinds of work, and the tilling of the soil, fall to their share. As a rule they are kindly treated, without being allowed to forget their duties. The Caduvei exchange the slaves among them for horses, cattle and various commodities[168].

Pohl states, that the Canoeiros had captured a young man and treated him well[169]. Nothing more being added, we cannot make out whether slavery exists.

Of the tribes of Central Brasil, visited by Von den Steinen, the principal are the Bakaïri, Paressi, Bororo, Suya and Yuruna. In his description of the Bakaïri, Paressi and Bororo he makes no mention of slavery. If it existed, this careful observer would certainly have mentioned it. Neither is a word about slaves to be found in Hensel’s description of the Coroados, who are often identified with the Bororo[170].

Among the Suya Von den Steinen observed Indians of other tribes, who were kept as slaves. The presents, which the author gave to one of these slaves, had to be delivered to his master[171].

The same writer speaks of captives residing among the Yuruna; but his short remark on this subject cannot lead us to a safe conclusion as to the existence of slavery among them[172].
