As for the longboat, she was brought close to the wind, on the larboard tack, with Dick at the helm and Marshall sitting beside him, while the three mariners, perceiving that their services were not likely to be required further for some time, stretched themselves out in the bottom of the boat and were soon fast asleep. For the first hour of their progress the land to windward merely presented the appearance of a black blur, indistinctly seen under the star-spangled indigo of the night sky; but by the end of that time something in the nature of outline began to reveal itself, while, half an hour later, a long tongue of land became distinctly visible broad on their weather bow, with two or three much smaller detached blotches rising out of the sea ahead. Standing up in the stern-sheets, Marshall scrutinised these appearances with the greatest care for several minutes; then, with a sigh of contentment, he sat down again. "It is all right, Dick," he said; "we have made a most excellent landfall. That long stretch of land yonder is Baru Island, and the small detached blots of blackness are the detached islets at its southernmost extremity which we saw marked on the chart. We must pass to leeward of them, lad, giving them a berth of at least a mile, because, if our chart is correct, there is a reef between us and them which we must avoid. If we can only get up abreast of those islets before the daylight comes I shall be satisfied, because we shall then be hidden from the sight of any fishing canoes which may happen to be outside Cartagena harbour; and, once inside Baru, I think we need not have the slightest fear of discovery. Moreover, I have an idea that we can make our way into the harbour from the back of Baru, without being obliged to go outside again, which will be a great advantage." "Have you formed any plan of action to be followed after we arrive at the back of the island?" demanded Dick. "Well, no; I can't say that I have," answered Marshall. "My experience is that, in the case of expeditions of this kind, it is of little use to scheme very far ahead. I have found that the best plan is to trust to luck, and be guided entirely by circumstances. My object, of course, is to penetrate to the town of Cartagena itself, and there pick up all the news that I can get hold of relative to the movements of the plate ship, seeing her, if possible, and so acquainting myself with her build, rig, and general appearance, so that if by any chance she should sail in company with other ships I may know for certain which is the craft that we must single out for attack. It may be possible for us to go up the harbour in the longboat, although I do not regard such a thing as very likely; there would be too much risk in it, I think, to justify such an attempt, at least until all other schemes have failed; and we are not out now in quest of adventure, or to incur unnecessary risks, but to obtain information; the adventure may come later on."
