That discipline served for the Negroes as it usually did for all colonials, whether the lawbreaker were slave, bondsman, or free citizen, is indicated by an entry in the Dick account: "2 thongs w^{th} Silk lashes 1/3." One must bear in mind that corporal punishment was accepted universally in the 18th century. Its application to slaves, however, usually was left to the discretion of the slave owner, so that the restraint with which it was administered depended largely upon the humanity and wisdom of the master. The use of the lash was more often than not delegated to the overseer, who was hired to run, or help run, the plantation. It was the overseer who had a direct interest in eliciting production from the field hands; a sadistic overseer, therefore, might create a hell for the slaves under him. It is clear from Mercer's records that some of his overseers caused problems for him and that at least one was a brutal man. For October 1747 a chilling entry appears in the account of William Graham, an overseer at Bull Run Quarters: "To Negroes for one you made hang himself. £35." Entered in the "Negroes" account, it reappears, somewhat differently: "To William Graham for Frank (Hanged) £35 Sterling. £50. 15." This is one of several instances on record of Negroes driven to suicide as the only alternative to enduring cruelties.[103] In this case, Graham was fined 50 shillings and 1293 pounds of tobacco. We do not know, of course, whether other Negroes listed as dead in Mercer's account died of natural causes or whether cruel treatment contributed to their deaths. In the case of a homesick Negro named Joe, who ran away for the third time in 1745, Mercer seems reluctantly to have resorted to an offer of reward and an appeal to the law. Even so, he declined to place all the blame on Joe. Joe had been "Coachman to Mr. Belfield of Richmond County" and in the reward offer Mercer states that Joe ... was for some time after he first ran away lurking about the Widow Belfield's Plantation.... He is a short, well-set Fellow, about 26 Years of Age, and took with him several cloaths, among the rest a Suit of Blue, lined and faced with Red, with White Metal Buttons, Whoever will secure and bring home the said Negroe, shall receive Two Pistoles Reward, besides what the Law allows: And as I have a great Reason to believe, that he is privately encouraged to run away, and then harboured and concealed, so that the Person or Persons so harbouring him may be thereof convicted, I will pay to such Discoverer Ten Pistoles upon Conviction. This being the third Trip he has made since I bought him in _January_ last, I desire he may receive such Correction in his Way home as the Law directs, when apprehended.[104]
