CHAPTER SIX
THE HEAT-RAY IN THE CHOBHAM ROAD
It is still a matter of wonder how the Martians are able to slay
men so swiftly and so silently. Many think that in some way they are
able to generate an intense heat in a chamber of practically absolute
non-conductivity. This intense heat they project in a parallel beam
against any object they choose, by means of a polished parabolic
mirror of unknown composition, much as the parabolic mirror of a
lighthouse projects a beam of light. But no one has absolutely proved
these details. However it is done, it is certain that a beam of heat
is the essence of the matter. Heat, and invisible, instead of
visible, light. Whatever is combustible flashes into flame at its
touch, lead runs like water, it softens iron, cracks and melts glass,
and when it falls upon water, incontinently that explodes into steam.
