window frame?

Hoping to test this further, I endeavored to move the apparatus to a
position where Mars would again be visible, but alas, I found it much
too heavy. I felt keenly disappointed at the sudden termination of this
strange phenomenon, but, upon reflection, I realized that it was only
the simultaneous disappearance of Mars and the glow on the film that had
caused me to attribute waves to that far source. The more I pondered
upon the matter, the more impossible it seemed, yet, strange to say, the
more convinced I became that the theory was correct. Light-waves, I
argued, unlike the wireless waves in common use, could be received only
when the two objects were in line of vision; but I realized that if they
were of Martian origin they were of remarkable magnification, projected
through space by some unknown and powerful agent, thousands of times
more powerful than electricity as we know it upon Earth. That the shadow
on the film had been that of a Martian, I dared not hope. Though my mind
continually reverted to this wild conjecture, I impatiently put it
aside, as the apparent impossibility of it all would force itself upon
me.

Nothing further could be done that night, and as I had worked hard all
day preparing for my experiment, without even stopping for meals, I now
felt the effect of the excitement I had undergone and resolved to take a
walk in the cool air, I wanted to think, and, if possible, to plan a
line of action for the morrow which would bring me better results, if my
theory of light-waves should prove to be correct. Needless to say, I
determined to cease my former experiments, and devote all my energy to
ascertaining whether my apparatus was actually responding to Martian
light-waves of remarkable integrity, and if such proved to be the case,
to put every effort into improving the device with the hope of obtaining
their import. I also determined to keep my discovery a secret, at least
for the present.

CHAPTER II.

THE MARTIAN.

I returned to my rooms with a much clearer conception of the conditions
with which I had to cope, if the waves to which my apparatus responded
should prove to be Martian waves. My mind was fully made up to proceed
as if this were an established fact, as, in order to give my best
efforts to improving my apparatus, I felt that I must eliminate all
scepticism. I clearly appreciated the advantage of moving my instrument
outside, where I could command a view of Mar
