Review A differential leveling loop began and closed on BM Tree (elevation 1314.08 ft). The backsight sum and foresight sum distances were kept approximately equal. Readings (in feet) listed in the order taken are 3.06 (+S) on BM Tree, 4.76 (−S) and 2.47 (+S) on TP1, 3.05 (−S) and 6.63 (+S) on BM X, 3.64 (−S) and 2.35 (+S) on TP2, and 3.13 (−S) on BM Tree. Prepare, check, and adjust the notes.
