Traffic with slaves was a very difficult matter to control. At first, a person trading with a slave was required to pay treble for the article purchased, and six pounds proclamation money.[59] Finally, traffic with slaves was permitted only on the basis of a written permission from the master, describing the article for sale. A person convicted for violation of this law was fined ten pounds, and the slave received not exceeding thirty-nine lashes.[60] If such a person did not have sufficient property to satisfy the fine, he was committed to jail. Traffic with slaves became more difficult to regulate as the slavery system expanded. The slave was not permitted to engage his services to anyone, nor could the master hire him out. For violation of this regulation, the slave might be taken in charge by a magistrate or free-holder and set to work for the county, for the benefit of the poor, for a period not exceeding twenty days; “any law, usage or custom to the contrary notwithstanding.”[61] It is noticed that these restrictions pertained primarily to the relations of the slaves with free negroes, Indians, traders, and poor whites, who were as a rule more or less inclined to disturb the order of the plantation. Their association with the whites in the home and at church was a matter of unwritten law. The domestic servants were more intimately associated with the whites and were frequently cultured.[62] There was very little effort on the part of the masters, in the early stages of the development of slavery, to teach or christianize the slaves. Many of them, however, learned to read, and joined churches, but they were not permitted to have separate church organizations.[63] 3. _The Runaway_: The runaway was one of the most difficult problems of slave government. The wild life of the slave in Africa, and the hardships of frontier American slavery naturally created a disposition in the slave to run away from his master’s plantation. Organized bands of slave-stealers, poor whites, and free negroes constantly took advantage of this attitude of the slave. This was one method by which the slave could, at least temporarily, break the bonds of slavery; and he did not always find life more severe in the camp than on the plantation. Runaways, aside from the economic loss to the slave-owners involved, might congregate and start an insurrection. Any outside contact made possible conspiracies, and created a real danger to the community. It was, therefore, a heavy fine for anyone to harbor a slave; and it was the duty of all citizens to arrest runaways.[64] The law against the aiding and harboring of runaways was made more severe by increasing the fine for its violation. Finally, to promote the escape of a slave from the colony became a felony and might involve the loss of life.[65]
