\paragraph{Hall's Pond Work Party.}  Twice a year, the Brookline
Conservation Commission and the Friends of Hall's Pond organize a work
party at Hall's Pond, a nature sanctuary located several blocks from
Epsilon Theta.  While this project is popular among the active members
of the house, alumni also often join in.  Thetans having attended
every work session over the past seven years make familiar faces to
neighbors having a similar interest in keeping local wetlands
beautiful.
