Problem $1(10$ points$)$

The sketch below is from a surveyor's field book and represents the results of a differential leveling loop. Prepare the field notes to accompany this sketch. All numerical values shown have units of feet. The symbol $"Y"$ represents an instrument setup location. The rod reading of $8\mathrm{.}864$ feet is the first measurement taken and $9\mathrm{.}092$ feet is the last measurement taken.

What is the closure error for this level loop? Note: You do not have to compute the adjusted elevations.
