the servant as long as possible. Indeed there are several examples of white servants who had to petition for their freedom because their masters attempted to hold them beyond the period of their indenture.72 The slave had no indenture. The contract was made with the seller of the slave, and he had no incentive to limit the term of service because that would serve only to limit his potential profits.73 The colony passed laws limiting the time of service for white servants who had no indenture because permitting masters to hold them for an unlimited period would discourage immigration. The African was not a voluntary immigrant, so there was no similar need to assure his time of service would be limited. Thus the method by which slaves were acquired made it easier to hold servitude for an indefinite time while economic forces worked against any limit being imposed. The colonists came to make money, and few, if any, had second thoughts about appropriating the labor of others in their quest for profit. Another factor that may have played a role in the white colonists' willingness to establish a system of lifetime servitude was the class based society from which they came. Although white servants came with the hope of bettering themselves, society in England had a substantially fixed class structure. Even if servant status was a product of an annual or an at-will contract, the servant in England was likely to remain in that status for life because he or she had no better alternative. The colonial indenture was necessary because servants in America had alternatives, but the master was unlikely to perceive anything wrong in a servant class which remained in servitude throughout their life. Although the indentured servant had rights to receive com, clothing and rights to land from his master when his term of servitude expired, the master owned all of the labor of the servant during the indenture period.74 In view of the high rate of mortality in the early years of the colony, term servants often died before their term expired.75 The sharp difference we see between servitude and slavery may have been less distinct in such a context. Finally, the African was different in so many ways from the white servant that it was possible, as the 1639 bills demonstrate, for the English colonists to view them as not entitled to the "rights of Englishmen." Even though many masters must have lived and worked alongside their servants and slaves, the initial barriers of religion, race, language and culture produced an attitude that perpetuated the gulf between negro slave and white master. Just as parents tend to perceive their children as children long after the child has reached maturity, so the attitudes produced in the initial relationship would color the master's perception of his slave to prevent the perception of human equality. Meanwhile, the indentured servant who shared the race, religion and language of the master was likely to identify with the master, hoping to become a master one day, and thus tending to share the same distanced view of the slave despite working together in the early years. Many of the differences between Englishmen and Africans also existed between the colonists and the indians. Indeed, some indians were taken as slaves in the early stages of colonization.76 As early laws indicate, however, slavery was dangerous to the society where the slave's kinsmen were armed nearby.77 Further, indians could escape back to their tribe. The African had no kin in the new land. In short, for the master, perpetual slavery was economically desirable, it was not foreclosed by contract or positive law, and a variety of other factors including the alien background of the slave, the hierarchical structure of english society, and the comparability of slave and servant status 13
