"I have told you," said the latter, "that I never saw the light before. I believe it to be the Bell Rock Light; but it would be as well to run close and see. I think I could tell the very stones of the tower, even in a dark night. Anyhow, 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."
