"You've been dreaming," said I, in a voice which was a very fair
imitation of Bill's own.

"Dreaming," repeated Bill, "dreaming! Ah, look there!"

He pointed with outstretched finger, and my heart seemed to stop beating
as I saw a man's head appear above the side. For a brief space it peered
at us in silence, and then a dark figure sprang like a cat on to the
deck, and stood crouching a short distance away.

A mist came before my eyes, and my tongue failed me, but Bill let off a
roar, such as I have never heard before or since. It was answered from
below, both aft and for'ard, and the men came running up on deck just as
they left their beds.

"What's up?" shouted the skipper, glancing aloft.

For answer, Bill pointed to the intruder, and the men, who had just
caught sight of him, came up and formed a compact knot by the wheel.

"Come over the side, it did," panted Bill, "come over like a ghost out of
the sea."

The skipper took one of the small lamps from the binnacle, and, holding
it aloft, walked boldly up to the cause of alarm. In the little patch of
light we saw a ghastly black-bearded man, dripping with water, regarding
us with unwinking eyes, which glowed red in the light of the lamp.

"Where did you come from?" asked the skipper.
