hankful."

"I have said," he replied, "that on that point you misconceive our
respective positions. No one supposes that you are indebted to us for
anything more than it was the duty of the Sovereign to give, as a mark
of the universal admiration and respect, to our guest from another
world; still less could any imagine that on such a trifle could be
founded any claim to a secret so invaluable. You will offend me much
and only if you ever again speak of yourself as bound by personal
obligation to me or mine. But as we are wishful to buy, so I cannot
understand any reluctance on your part to sell your secret on your own
terms."

"I think, Prince," I replied, "that I have already asked you what you
would think of a subject of your own, who should put such a power into
the hands of enemies as formidable to you as you would be to the races
of the Earth."

"And _I_ think," he rejoined with a smile, "that I reminded you how
little my judgment would matter to one possessed of such a power. I
have gathered from your conversation how easily we might conquer a
world as far behind us in destructive powers as in general
civilisation. But why should you object? You can make your own terms
both for yourself and for any of your race for whom you feel an
especial interest."

"A traitor is none the less a despicable and loathsome wretch because
his Prince cannot punish him. I am bound by no direct tie of loyalty
to any Terrestrial sovereign. I was born the subject of one of the
greatest monarchs of the Earth; I left his country at an early age,
and my youth was passed in the service of less powerful rulers, to one
at least of whom I long owed the same military allegiance that binds
your guards and officers to yourself. But that obligation also is at
an end. Nevertheless, I cannot but recognise that I owe a certain
fealty to the race to which I belong, a duty to right and justice.
Even if I thought, which I do not think, that the Earth would be
better governed and its inhabitants happier under your rule, I should
have no right to give them up to a conquest I know they would fiercely
and righteously resist. If--pardon me for saying it--you, Prince,
would commit no common crime in assailing and slaughtering those who
neither have wronged nor can wrong you, one of themselves would be
tenfold more guilty in sharing your enterprise."

"You shall ensure," he replied, "the good government of your own world
as you will. You shall rule it
