completed over eight years aga, chatted
very entertalningly on the subject of
the varying alterations of his charge.
MI Hawkins has taken the readings of
the indicators each day for something
over eight years. and probably knows
much more about the variations than
any one else connected with the monu-
ment.
The variation does not get more
than three or four inches out of the
plumb line" he said, though that is an
extreme The variation is very irregu-
lar at all times, and l have not entirely
made up my mind yet as to just what
causes 1t. l have seen it stated in va
rious publications that it is due to the
expansion and contraction caused by
the heat of the sun. The people who
lay 1t to this cause, however, assert
that 1t moves toward the north, be-
cause the sun is hottest in the south.
My experience of eight years has been
that the monument moves toward the
southwest Each month we use the
daily observations to plan out chart
Oh the movement, and it is almost inva-
rlably toward the southwest. I guess
there is not much doubt that the sun
does have some influence on it, but 1
should think that the north side, being
coolest, would contract and draw the
monument that way. Instead, howev-
er, 1t goes toward the southwest. I am

"It has also been stated that the vari-
alton is due to winds NV exnerience
has been that on DAVIS when the wind
was blowing sixty miles an hour-so
hard. in fact that Won co,ld NOT stand
up by yourself our there on the hill-at
the very time when Won would expect
the Indicator To show great variation
In the direction in which tho wind was
blowing-thare wouId stil1 NOT he the
least bending in that direction. have
noticed that time and again At other
times. in a dead calm T have been sur-
prised, on looking at the Indicator, to
! find the pendulum swavinr and bob-
bling around as thouoh tbe monument
was shaking in an earthouake At
such times it would indicate a big yari-
alton, This cannot be due TO air chr
rents within the monument because
the pendulum ia protected by a cylin-
der. and the Indicators are protected in
a closed closet We have tee+ad tbe in
dicators when the elevator is running

has never had tha SLIGHTEST inf,uenoe on
