Some of the servants upon the expiration of their terms of indenture secured work as overseers, if they found it impossible to obtain patents to estates of their own. Throughout the greater part of the colonial period the position occupied by the overseer was preferable to that of the poorest class of independent farmers. His usual remuneration was a part of the crop. Sometimes he received only one-tenth of what was produced, but often his share was much greater, for cases are on record where he was to keep one half. Later the pay was regulated by the number of persons under his management, slaves as well as hired and indentured servants forming the basis of the calculation. Under both systems of payment he was liberally rewarded for his services.[194] The control of many laborers, the necessity for a knowledge of all the details of farming, the contact with his employer in matters of business made requisite in the overseer both intelligence and the power of command. Many were men of much ability and were trusted by the planters with the entire management of their estates. When the overseer worked upon the "home" plantation, he usually dwelt either in the mansion itself or in one of the group of houses nearby, in which were sleeping rooms used by members of the household or guests. He was treated always with courtesy and was accorded some social recognition by his aristocratic employer. Sometimes the overseer through ability and care accumulated property and became an independent planter. Occasionally the servants upon the close of their term of indenture earned a subsistence as hired laborers. This, however, was not very common, for the opportunities for an independent existence were so great that few would fail to grasp them. There could be no necessity for laboring for others when land could be had so cheaply. Those that did hire themselves out were tempted usually by the excessive wages that could be obtained from wealthy planters. Throughout the 17th century, the difficulty of obtaining a sufficient supply of servants to keep in cultivation the tobacco fields of the colony, created a lively demand for labor and made wages higher than in England. Even in the early years of the century this state of affairs prevailed, and we find planters complaining of the excessive cost of hired labor and making urgent requests for indentured servants.[195] Despite the high price of tobacco that prevailed before 1660, it was the general opinion that no profit could be made from it when hired laborers were used in its cultivation, and it is probable that they were never employed except when the supply of servants fell far short of the demand. In the 18th century, when the importation of many thousands of slaves had lowered the price of labor in the colony, the employment of hired hands became still less frequent.
