*MYSTERIOUS FIRE MELTS DEEP SNOW*
Hunters Tell of Strange Green Light Which Came Down From Sky
Neillsville (Wis.) Jan. 15. ?
While homeward bound in a sleigh
from a wolf-hunting expedition
west of here, Leo Williamson, editor,
and Will Dangers, merchant,
witnessed a strange phenomenon
when the snow in the road ahead
of them for several hundred feet
was melted by a nebulous green
fire, leaving the highway covered
with several inches of mud.
Williamson said he and his companion
first noticed a faint green
light in the sky before them. In
less than a minute it had approached
to within a few hundred
feet and seemed to 2be [sic] whirling
rapidly and giving out a high-pitched
hum. Its height was estimated
at 300 feet and its breadth
at fifty feet. The light hovered a
moment and suddenly descended to
the road. A hissing noise followed
and a huge cloud of steam swept
Before they were able to get the
team turned around, the greenish
haze was within thirty feet of
them, then veered off, fused the
fence wires and scorched a path
through a field for nearly ten rods.
Then, almost as suddenly as it had
appeared, the light flickered a
moment and vanished.
Williamson said he and Dangers
examined the road and found it
was too hot to touch and that the
mud was six inches deep in some
places. Their only theory is that
some condition of the atmosphere
had generated a huge charge of
electricity which dissapated [sic] itself
in heat when it touched the earth
and was grounded.
