325 Poplar St.

Are the published yearly
means as follows probably
correct and has there been
any change in the zero of
the water gauge (staff) above
it's reference mark since
1868 - if so it is not noted in
our office. Can you re-examine
the height of the zero above the
bench mark on Poplar St. ["Willow" crossed out]
and furnish me the data for
the reduction of present water
