It was, in any case, no easy matter to manage the Hottentots and Bushmen within the Colony. Up to the time of Lord Caledon's administration (1807-11) they had been allowed to run wild through the region without restraint other than their somewhat chaotic ideas of chieftainship, their innate belief in the natural superiority of any kind of a white man, and the rude justice, or injustice, of the Dutch farmer. Many of them lived as voluntary dependents of the settlers, and constituted a sort of movable slave class which associated with the permanent slaves and were treated much as they were, while retaining the nominal right to transfer their services. Children born of unions between Hottentot women and the imported slaves constituted a body of apprentices whom the farmers had the right to keep for a certain number of years, and who then became free. Practically, however, they were as much slaves as any other black children pertaining to the property. Those of the Hottentots who did not connect themselves with the farmers in any way became rovers and vagrants, who were willing to do almost anything--except steady work--for brandy and tobacco. This was the material selected by Dr. Van der Kemp and other missionaries for reclamation and protection. When the Circuit Courts were instituted in 1811 two of the best known missionaries brought a number of charges against the Boer families on the frontier, accusing them of varied acts of violence and forms of oppression in connection with their slaves and Hottentot servants. A large number of families and a thousand witnesses were involved, and great expenses were incurred by the accused whether they were found innocent or guilty. [Sidenote: Charges of Cruelties] No case of murder was proved, though several were charged. Without going minutely into the result of the charges, it seems evident from our knowledge of the Boer character as it then was, and afterwards proved to be, that cruelties were more than probable. At the same time there is every proof of the utter unreliability of native evidence in any matter involving controversies between white men, or affairs in which his own interests, or fancied interests, appear to be at stake.
