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 was secure, then. I knew she could rise no higher,
and I was right. She sailed behind all the peaks and
never succeeded in hoisting her disk above a single one
of them.

While the moon was behind one of those sharp fingers,
its shadow was flung athwart the vacant heavens
--a long, slanting, clean-cut, dark ray--with a streaming
and energetic suggestion of FORCE about it, such as the
ascending jet of water from a powerful fire-engine affords.
It was curious to see a good strong shadow of an earthly
object cast upon so intangible a field as the atmosphere.
