"I take it as pretty certain," Frank said, as he, George Lechmere, the skipper, and Dominique bent over the chart; "that the schooner is somewhere in this bay. She has certainly not made her headquarters anywhere along the south coast. In the first place, she has seldom been seen, and in the second we have examined it thoroughly. Therefore I take it that she is somewhere here, unless, of course, she has sailed for Cuba. But I don't see why she should have done that. The coast there is a good deal more dangerous than that of San Domingo. He could not want a better place for cruising about than this bay. You see, it is about ninety miles across the mouth, and over a hundred to Port au Prince, with indentations and harbours all round, and with the island of Genarve, some forty miles long, to run behind in the centre. He could get everything he wants at Port au Prince, or at Petit Gouve, which looks a good-sized place.

"I should say, in the first place, that we could not do better than run down at night to the island of Genarve, and anchor close under it. From there we shall see him if he comes out of Port au Prince, or Petit Gouve, whichever side he may take; and by getting on to an elevated spot have a view of pretty nearly the whole bay. Looking at it at present, the two most likely spots for him to make his headquarters are in that very sheltered inlet behind the point of Halle on the north side, or in the equally sheltered bay and inlet under the Bec de Marsouin on the south. From Genarve we ought to be able to see him coming out of either of them. It is not above five-and-twenty miles from the island to the Bec de Marsouin, and forty to the point of Halle. We might not see him come out from there, but we should soon make him out if he were coming down from Port au Prince."

It was agreed that this was the best plan to adopt. It might lead to their sighting the schooner in a day or two, while to row round the bay and search every inlet in it would take them a fortnight. From Genarve, too, a forty-mile sail in the gig would take them into Port au Prince, which the brigantine might possibly have made its headquarters. Accordingly, after waiting until nightfall, they got up sail, and anchored at six in the morning in a small bay in the island of Genarve. Here they would not be likely to attract the notice of any ship passing up to Port au Prince, unless, which was very unlikely, one came along close to the shore.

As soon as the anchor was dropped, both boats rowed to shore. Frank, George Lechmere, Pedro, and four sailors, with a basket of provisions, started at once for the highest point in the island, some four miles distant. Dominique went along the shore with two sailors, to make inquiries at any villages they came to.

On reaching the top of the hill, Frank saw that, as he had expected, it commanded an extensive view over the bay on each side of the island, which was but some six miles across. A village could be seen on the northern shore, some three miles distant; and to this Pedro, with one of the sailors, was at once despatched. Both parties rejoined Frank soon after midday. The schooner had been noticed passing the island several times, but much more often on the southern side than on the northern. The negroes on that side were all agreed that she generally kept on the southern side of the passage, and that more than once she had been seen coming from the south shore, and passing the western point of the island on her way north.

"That looks as if she came from Petit Gouve, or the bay of Mitaquane, or that under the Bec de Marsouin," Frank said.

"Dat is it, sar," Dominique agreed. "If she want to go north side of bay from Port au Prince, she would have gone either side of island. I expect she lie under de Bec. Fine, safe place dat, no town there, plenty of wood all round, and villages where she get fruit and vegetables; sure to be little stream where she can get water."

The watch was maintained until sunset, but, although a powerful telescope had been brought up, no vessel at all corresponding to the appearance of the brigantine was made out.

At six o'clock the next morning Frank was again at the lookout, and scarcely had he turned his telescope to the south shore than he saw the brigantine come out from behind the Bec de Marsouin and head towards the west. The wind was blowing from that quarter, and after a few minutes' deliberation, Frank told the men to follow him, and dashed down the hill. In half an hour he reached the shore opposite the yacht, and at his shout the dinghy, which was lying at her stern, at once rowed ashore.

"Get up the anchor, captain, and make sail. I have seen her. She has just come out from the Bec, and is making west. As the wind is against her, it seems to me that he would never choose that direction to cruise in unless he was starting for Cuba, and I dare not let the opportunity slip. If he once gets clear away we may have months of work before we find him again, and as the wind now is, I am sure that we can overhaul him long before he can make Cuba. Indeed, as we lie, we are nearer to that coast than he is, and can certainly cut him off."
