"I am of another world," I answered, "the great planet Earth, which
revolves about our common sun and next within the orbit of your
Barsoom, which we know as Mars. How I came here I cannot tell you, for
I do not know; but here I am, and since my presence has permitted me to
serve Dejah Thoris I am glad that I am here."

She gazed at me with troubled eyes, long and questioningly. That it
was difficult to believe my statement I well knew, nor could I hope
that she would do so however much I craved her confidence and respect.
I would much rather not have told her anything of my antecedents, but
no man could look into the depth of those eyes and refuse her slightest
behest.

Finally she smiled, and, rising, said: "I shall have to believe even
though I cannot understand. I can readily perceive that you are not of
the Barsoom of today; you are like us, yet different--but why should I
trouble my poor head with such a problem, when my heart tells me that I
believe because I wish to believe!"

It was good logic, good, earthly, feminine logic, and if it satisfied
her I certainly could pick no flaws in it. As a matter of fact it was
about the only kind of logic that could be brought to bear upon my
problem. We fell into a general conversation then, asking and
answering many questions on each side. She was curious to learn of the
customs of my people and displayed a remarkable knowledge of events on
Earth. When I questioned her closely on this seeming familiarity with
earthly things she laughed, and cried out:

"Why, every school boy on Barsoom knows the geography, and much
concerning the fauna and flora, as well as the history of your planet
fully as well as of his own. Can we not see everything which takes
place upon Earth, as you call it; is it not hanging there in the
heavens in plain sight?"

This baffled me, I must confess, fully as much as my statements had
confounded her; and I told her so. She then explained in general the
instruments her people had used and been perfecting for ages, which
permit them to throw upon a screen a perfect image of what is
transpiring upon any planet and upon many of the stars. These pictures
are so perfect in detail that, when photographed and enlarged, objects
no greater than a blade of grass may be distinctly recognized. I
afterward, in Helium, saw many of these pictures, as well as the
instruments which produced them.

"If, then, you are so familiar with eart
