The Manual has guided the original surveys and resurveys of the Public Lands, 1st through the General Land Office, and since 1946, through the Bureau of Land Management, Department of the Interior. While not written specifically for non-Federal surveyors, the principles contained in the Manual on the subject of retracement are an important part of private surveying in the 30 Public Land States. Further, many States have formally adopted the Manual in statute, rule, and/or case law as guidance for private licensed surveyors.
