yhow, I know the rock itself too
well to mistake it."

"Be there plenty watter?"

"Ay; on the east side, close to the rock, there is enough water to
float the biggest ship in your navy."

"Good; we shall go close."

There was a slight lull in the gale at this time, and the clouds
broke a little, allowing occasional glimpses of moonlight to break
through and tinge the foaming crests of the waves. At last the light,
that had at first looked like a bright star, soon increased, and
appeared like a glorious sun in the stormy sky. For a few seconds it
shone intensely white and strong, then it slowly died away and
disappeared; but almost before one could have time to wonder what had
become of it, it returned in the form of a brilliant red sun, which
also shone for a few seconds, steadily, and then, like the former,
slowly died out. Thus, alternating, the red and white suns went round.

In a few minutes the tall and graceful column itself became visible,
looking pale and spectral against the black sky. At the same time the
roar of the surf broke familiarly on Ruby's ears. He steered close
past the north end of the rock, so close that he could see the rocks,
and knew that it was low water. A gleam of moonlight broke out at the
time, as if to encourage him.

"Now," said Ruby, "you had better go about, for if we carry on at
this rate, in the course we are going, in about an hour you will
either be a dead man on the rocks of Forfar, or enjoying yourself in
a Scotch prison!"

"Ha! ha!" laughed the Frenchman, who immediately gave the order to
put the vessel about; "good, ver good; bot I was not wish to see the
Scottish prison, though I am told the mountains be ver superb."

While he was speaking, the little vessel lay over on her new course,
and Ruby steered again past the north side of the rock. He shaved it
so close that the Frenchman shouted, "_Prenez garde_", and put a
pistol to Ruby's ear.

"Do you think I wish to die?" asked Ruby, with a quiet smile. "Now,
captain, I want to point out the course, so as to make you sure of
it. Bid one of your men take the wheel, and step up on the bulwarks
with me, and I will show you."

This was such a natural remark in the circumstances, and moreover so
naturally expressed, that the Frenchman at once agreed. He ordered a
seaman to take the wheel, and then stepped with Ruby upon the
bulwarks at the stern of the vessel.

"Now, you see the position of the lighthouse," said Ruby, "w
