where that red light was located;
he thinks he could throw a stone from the one place to
the other. But he couldn't, for the difference between
the two altitudes is more than three thousand feet.
It looks impossible, from below, that this can be true,
but it is true, nevertheless.

While strolling around, we kept the run of the moon all
the time, and we still kept an eye on her after we got back
to the hotel portico. I had a theory that the gravitation
of refraction, being subsidiary to atmospheric compensation,
the refrangibility of the earth's surface would emphasize
this effect in regions where great mountain ranges occur,
and possibly so even-handed impact the odic and idyllic
forces together, the one upon the other, as to prevent
the moon from rising higher than 12,200 feet above
sea-level. This daring theory had been received with frantic
scorn by some of my fellow-scientists, and with an eager
silence by others. Among the former I may mention
Prof. H----y; and among the latter Prof. T----l. Such
is professional jealousy; a scientist will never show
any kindness for a theory which he did not start himself.
There is no feeling of brotherhood among these people.
Indeed, they always resent it when I call them brother.
To show how far their ungenerosity can carry them, I will
state that I offered to let Prof. H----y publish my great
theory as his own discovery; I even begged him to do it;
I even proposed to print it myself as his theory.
Instead of thanking me, he said that if I tried to
fasten that theory on him he would sue me for slander.
I was going to offer it to Mr. Darwin, whom I understood
to be a man without prejudices, but it occurred to me
that perhaps he would not be interested in it since it did
not concern heraldry.

But I am glad now, that I was forced to father my intrepid
theory myself, for, on the night of which I am writing,
it was triumphantly justified and established. Mont Blanc
is nearly sixteen thousand feet high; he hid the moon utterly;
near him is a peak which is 12,216 feet high; the moon slid
along behind the pinnacles, and when she approached that
one I watched her with intense interest, for my reputation
as a scientist must stand or fall by its decision.
I cannot describe the emotions which surged like tidal
waves through my breast when I saw the moon glide behind
that lofty needle and pass it by without exposing more
than two feet four inches of her upper rim above it;
I
