From The Crow's Nest

The night passed without incident, except for one thing that we were
unable to verify. At six bells, during the darkest hour of the night
that precedes the early dawn of summer, Adams, from the crow's-nest,
called down, in a panic, that there was something crawling on all
fours on the deck below him.

Burns, on watch at the companionway, ran forward with his revolver,
and narrowly escaped being brained--Adams at that moment flinging
down a marlinespike that he had carried aloft with him.

I heard the crash and joined Burns, and together we went over the
deck and, both houses. Everything was quiet: the crew in various
attitudes of exhausted sleep, their chests and dittybags around
them; Oleson at the wheel; and Singleton in his jail-room, breathing
heavily.

Adams's nerve was completely gone, and, being now thoroughly awake,
I joined him in the crow's-nest. Nothing could convince him that
he had been the victim of a nervous hallucination. He stuck to his
story firmly.

"It was on the forecastle-head first," he maintained. "I saw it
gleaming."

"Gleaming?"

"Sort of shining," he explained. "It came up over the rail, and
at first it stood up tall, like a white post."

"You didn't say before that it was white."

"It was shining," he said slowly, trying to put his idea into
words. "Maybe not exactly white, but light-colored. It stood
still for so long, I thought I must be mistaken--that it was a
light on the rigging. Then I got to thinking that there wasn't
no place for a light to come from just there."
