<P> In some cases, the indenture was made with a ship's master, who on - sold the indenture to an employer in the colonies . Most indentured servants worked as farm laborers or domestic servants, although some were apprenticed to craftsmen . </P> <P> The terms of an indenture were not always enforced by American courts, although runaways were usually sought out and returned to their employer . </P> <P> Between one - half and two - thirds of white immigrants to the American colonies between the 1630s and American Revolution had come under indentures . However, while almost half the European immigrants to the Thirteen Colonies were indentured servants, at any one time they were outnumbered by workers who had never been indentured, or whose indenture had expired, and thus free wage labor was the more prevalent for Europeans in the colonies . Indentured people were numerically important mostly in the region from Virginia north to New Jersey . Other colonies saw far fewer of them . The total number of European immigrants to all 13 colonies before 1775 was about 500,000; of these 55,000 were involuntary prisoners . Of the 450,000 or so European arrivals who came voluntarily, Tomlins estimates that 48% were indentured . About 75% of these were under the age of 25 . The age of adulthood for men was 24 years (not 21); those over 24 generally came on contracts lasting about 3 years .

As historian Richard Hofstadter pointed out, "Although efforts were made to regulate or check their activities, and they diminished in importance in the eighteenth century, it remains true that a certain small part of the white colonial population of America was brought by force, and a much larger portion came in response to deceit and misrepresentation on the part of the spirits (recruiting agents)." One "spirit" named William Thiene was known to have spirited away 840 people from Britain to the colonies in a single year . Historian Lerone Bennett, Jr. notes that "Masters given to flogging often did not care whether their victims were black or white ." </P>
