A differential leveling circuit began on BM Hydrant $($elevation $1823\mathrm{.}65ft)$ and closed on BM Rock $($elevation $1841\mathrm{.}71ft).$ The plus sight and minus sight distances were kept approximately equal. Readings $($in feet$)$ given in the order taken are $8\mathrm{.}04($S$)$ on BM Hydrant, $5\mathrm{.}63(-S)$ and $6\mathrm{.}98($S$)$ on TPI, $2\mathrm{.}11(-S)$ and $9\mathrm{.}05(S)$ on BM I, $3\mathrm{.}88(-S)$ and $5\mathrm{.}55($S$)$ on BM $2,5\mathrm{.}75(-S)$ and $10\mathrm{.}44($S$)$ on TP$2,$ and $4\mathrm{.}68(-$S$)$ on BM Rock. Prepare, check, and adjust the notes
