How were 'bearing trees' identified in early GLO surveys according to Edward Tiffin's instructions?

In early General Land Office (GLO) surveys, bearing trees were critical for establishing property boundaries and reference points. According to Edward Tiffin's instructions, these trees were blazed on the side facing the post to indicate their significance in relation to the surveyed land. The specific method described by Tiffin included creating a blaze with one axe notch, which served as a visible mark, and additionally, these trees were marked with important numerical identifiers: section, township, and range numbers. This systematic approach ensured that the bearing trees were not only identifiable but also provided context regarding their location in relation to the surveyed plot of land. This clear identification method was essential for the continuity and accuracy of land surveying practices, facilitating future reference to the exact boundaries established during the survey.
