Secrets of the Hartness House

The Hartness House was built by former Governor of
Vermont, engineer, chief executive officer, inventor and wealthy
industrialist James Hartness.
This country inn is unique in that it features
its own museum, astronomy observatory and antique telescope with
a unique equatorial drive system. More unusual is the secret tunnel
system built by Hartness to access the observatory, museum and his
secret workshop.
Guests of the Hartness House Inn have an opportunity to tour the secret
tunnel, view the private workshop of Mr. Hartness, and see the observatory
and telescope. Guided tours are given by reservation only
to guests of the Inn and by private invitation of the owners and
Stellafane club members.
In February 1924, Popular Science magazine did a feature
article on the underground system of rooms and tunnels
including this drawing of the underground network
of rooms and tunnels..

The Secret Underground Tunnels
The Hartness secret underground tunnel was built in 1912. The
entire tunnel system is composed of three main tunnels and one service
tunnel running underneath the longest tunnel. The longest of the main
tunnels runs 242 feet from the Main House to the Observatory. A secondary
tunnel runs for 183 feet from the workshop/museum to a secret exit
to Common Street. The tunnel system was built to provide easy access
to the Hartness underground study and workshop and the observatory. |
|
The secret tunnel is accessed from Main House. You
descend 30 feet below the house. Once you past the locked
door, you enter the main tunnel. Dark and dank, it averages
35 to 43 degrees year round. |
 |
Once inside the main tunnel, you feel the cold immediately. Covered
in cobwebs, you make your way to the first turn where you must
turn left -- never open the door on the right.
Following an unfortunate accident, the door on the right has been
permanently closed to the public. |
 |
| Continuing down the main tunnel, the cold continues
to permeate you. Dark except for the few incandescent lights,
you need to be especially careful of spiders hanging from above. |
 |
The tunnel is long and getting more dark. The
cold is now combined with an unusal humidity.
The lighting
system is old and frequently fails. Once the lights go
out you are surrounded in pitch blackness and the cold is even
more apparent as you begin is feel the humid, dank air surrounding
you. |
 |
The tunnel turns again. The tunnel conducts and
amplify sounds. Listen carefully and you may notice sounds
that appear to come from the walls.
The tunnel appears to be closing in, but it is only a feeling. The
cobwebs are getting thicker as is the air.
|
 |
You finally reach the end of the main tunnel. You
need to pass through another locked door and you stand in front of
an unusual spiral staircase. Tight and following a sharp
turn you descend to the second level.
You may wonder why there are so many locked doors. What
could the locked doors be protecting? |

The Hartness Equatorial Turret Telescope and Observatory
In
1910, James Hartness built one of the most unique telescopes
for an individual in the United States. The Hartness Equatorial
Turret Telescope employs a sophisiticated motor-drive, transmission
system and clock drive to replicate the rotation of the earth.
Using the equatorial drive system makes it possible to view heavenly
objects over extended periods of time notwithstanding the rotation
of the earth.
The
telescope and the observatory were completely engineered, designed
and manufactured by
James Hartness in Springfield, Vermont with the exception of
the turret dome which was manufactured in Massachusetts.
The Hartness Equatorial Turrent Telescope was adwarded a US patent
No. 1,045,142 on November 12, 1912.

The Observatory is accessed from Main House. You
follow the main tunnel to the end and ascend the spiral staircase
at the end of the tunnel. |
 |
Inside the Observatory, the temperature matches the
outside temperature -- intensely cold in the winter and hot in the
summers.
The observatory has the feel of a submarine -- cylindrical in
shape with few portholes at one end. Aligning the telescope
is done by moving the turrent and telescope by coordinates
-- there is no visual reference of the outside.
The equatorial drive, visible in the center, is driven by an electric
motor sitting underneath the viewing platform. The telescope
is mounted to the dome and the equatorial drive rotates the dome
turret. |
 |
A closer view of the equatorial
drive shafts illustrate
the three shafts: clockwise-counterclockwise gear shift (left), main
drive shaft (center), and the equatorial drive shaft (right).
The round object directly top center is the clutch that connects
the motor drive to the clock system that will rotate the turret
dome. |
 |
Lens are inserted into the telescope lens holder
shown here.
The telescope is moved in a north-south direction by
turning the Declination gear shown here as the large disk. A
hand crank is inserted onto the spline protruding from the
lower center of the image. Turning the crank raises
and lowers the telescope. A vernier shows the amount
of degrees of declination of the telescope. |
 |
| Standing on the viewing platform, you can see the clockwork
gear system that when engaged rotates the telescope turret in the
opposite direction and speed of the earth's rotation. When
engaged, the movement is barely perceptable. |
