6. Land Ordinance 1785 The surveying crew
The task of surveying the Northwest Territory was enormous. The work was carried out by hand, and the entire countryside, including swamps, cane breaks, and marshes, was crossed. A survey crew typically consisted of a deputy surveyor, responsible for directing the operation with the use of a magnetic compass; two chainmen, who stretched the traditional four-rod measuring chain on the survey line; at least one flagman to mark the spot toward which the chainmen worked; one or two axmen who cleared the line of vision and blazed corners; and perhaps a hunter and a cook. Although the task was physically arduous, many men competed for surveyors' jobs, since it offered them an opportunity to scout the best land in a given area.
