In five minutes the Osprey was under way, with all sail set. The wind was nearly due west, and as Cuba lay to the north of that point, she had an advantage that quite counter-balanced that gained by the start the Phantom had obtained. In two hours the lookout at the head of the mast shouted down that he could perceive the brigantine's topsail.
"She is sailing in towards the land on that side," he said. "She has evidently made a tack out, and is now on the starboard tack again."
"It will be a long leg and a short one with her, sir," the skipper said. "I think that if we were in her place we could just manage to lay our course along the coast, but with those square yards of hers, she cannot go as close to the wind as we can. As it is, we can lay our course to cut her off."
"It would be rather a close pinch to do so before she gets to the head of the bay," Frank said.
"Yes, sir, and I don't suppose that we shall overhaul her before that, but we certainly shan't be far behind her by the time she gets there. I think that we shall cut her off if the wind holds as it does now. At any rate, if she should get there first, we should certainly lie between her and Cuba, and she will have either to run back, or to round the cape, or to run east or south. I wish the wind would freshen; but I fancy that it is more likely to die away. Still, she is walking along well at present."
Even Frank, anxious as he was, could not but feel satisfied as he looked at the water glancing past her side. She was heeling well over, and the rustle of water at her bow could be heard where they were standing near the tiller. Andrews, the best helmsman on board the yacht, held the tiller rope, and Perry was standing beside him.
From time to time Frank went up to the crosstrees.
"We are drawing in upon her fast," he said, "but she is travelling well, too; much better than I should have thought she would have done with that rig. I think she has got a better wind than we have. She has only made one short tack in for the last two hours."
The captain's prognostication as to the wind was verified, and to Frank's intense annoyance it gradually died away, and headed them so much that they could no longer lie their course.
"What shall we do, sir? Shall we hold across to the south shore and work along by it, as the schooner is doing, or shall we go about at once?"
