"Just come here and look at this map, Mr Fortescue," he said, and he spoke with the air and in the tones of a man who is so utterly dazed with disappointment that he begins to doubt the evidence of his own senses. "Just give me your opinion, will ye. I cannot understand this business at all. This map, although only a free-hand sketch, seems to me to be perfectly accurate. There, you see, is the mouth of the river, just as we found it; there are the little islets that we passed immediately after getting inside; there are the dry mud-banks; and there, you see, the river widens out, in precise accordance with our experience; here it narrows again at the bend; there is where the boats are lying concealed; and this," laying his finger upon a particular part of the sketch, "is the creek that we are now looking at; and there is the town of Olomba. It all seems to me to be absolutely correct. Does it not appear so to you?" "Certainly, sir," I answered. "The sketch answers in every particular to what we have seen since entering the river--answers to it so perfectly, indeed, that it might have been copied from a carefully plotted survey." "Exactly," assented the skipper. "Yet it is nothing of the kind; for with my own eyes I saw it drawn from memory by a man whom I happened to meet in one of the third-rate hotels in Freetown, which are frequented by the masters and mates of palm-oil traders and the like. I happened to hear him mention that he had been in and out of the Fernan Vaz at least a dozen times, in his search for cargo along the coast, so I waited until the people with whom he was talking had left him, and then I entered into conversation with him, finally inducing him to furnish me with this sketch." "And was it from him, sir, that you also obtained the information upon the strength of which you determined upon this expedition?" I asked. "Oh, no," answered the skipper. "I had that from quite a different source, in a very different kind of house. The people who told me about King Olomba's raid, and the plans laid by the slavers for carrying off the prisoners, were slavers themselves; and they told me of the scheme because they believed me to be the master of a slaver waiting for information from the Senegal river. The cream of the joke was that these fellows should have told me--_me_, the captain of the _Psyche_-- that the scheme had been carefully planned with the express object of putting the _Psyche_ upon a false scent and so getting her out of the way while the negroes were being shipped."
