facility around 1903 ending the "city gas" production on a fault across the
street from "Red Spring #1" where it's said the settlement may have begun.
They were looking for the leakage of coal tar from coal gas manufacturing
that they thought may have resulted from leakage into one of those storm
drains that ran under the plant. They said they were going to send a one
of those cameras down the storm drain. Apparently it was hauled away,
perhaps to be made into the "fibre pipe" listed on the sewer history site
in the New York section, apparently 1200 miles of it are in the
Empire State Building!

A bunch of it went into making Germany an economic power when it was
discovered how to take the "coal tar" a byproduct of "cooking" coal into
gas, and creating fabric dyes. The gasholder in Saratoga, NY has been
recently placed on the National Register of Historic Places. I was working
for Grossman and Associates and the EPA, and we used a cesium based hand
held proton magnetometer to locate the remains of the other gasholders and
associated structures, there on the border of the Adirondack/Taconic regions
in record heat. There is also a large natural gasline running through the
small yard. The company doing the environmental work also doing
