52 WILLIAM AND MARY QUARTERLY contained only two taxable slaves; another quarter had only one. On these, the lives of the slaves perhaps paralleled those of poor white ten- ants. Like Mingo, Dick, and Toby, these slaves apparently operated small family farms away from their master's home plantation. Eleven of the thirty-seven quarters contained three or four adult slaves, while between five and twenty taxable adults lived on the remaining fifteen. Some of the slaves on these larger operations must have enjoyed some measure of responsibility, status, and power.60 If it is assumed that one black on each of the thirty-seven quarters held a position that approximated that of an overseer, 3 percent of the slave men in the county in 1733 were so em- ployed. To these thirty-seven should be added another handful of slaves who lived either on the home plantations of widows with no resident white man or on estates where adult blacks greatly outnumbered adult whites. In such situations black men probably assumed some of the responsibility for operating the farm and for supervising the work of other slaves.61 A firm estimate of the number of slaves engaged in domestic service during the 17205 is impossible, but there can be little doubt that their ranks were swelled as the wealth and labor force of the great planters grew. Nor is it possible to measure the number who found work at the stores and taverns located in the several service centers (most still too small to deserve the name of towns) that were beginning to emerge in the region or in the minor industrial enterprises organized by wealthy planter- merchants."2 However, when these possibilities are added to the chances to acquire a craft or a supervisory job, it becomes reasonable to suggest r'° For the freedom and power of men in such positions see the example of Charles Calvert's black overseer who harbored a runaway slave for about a month in the winter of 1728-1729, Maryland Gazette (Annapolis), Dec. 24-31, 1728, Jan. 21-28, 1729. See also Mullin, Flight and Rebellion, 171-172. 61 The tax list is in the Black Books, II, 109-124, Hall of Records. Because the list does not distinguish slaves by sex, it has been necessary to estimate the number of black men by applying a sex ratio of 1.500 to the total number of taxable-age slaves.
