And, springing from my chair, to the no small consternation of my companions, who evidently thought I had suddenly gone demented, I rushed away to my state-room and, seizing a sheet of paper, jotted down the system that had just recurred to my memory. Then, heedless of my unfinished breakfast and everything else, I drew out the precious document itself, and, using the key that had come to me in such an extraordinary manner, soon discovered, to my inexpressible delight, that I really was at last upon the right track. I met with a few difficulties, it was true; but, braced-up and encouraged by what I had already achieved, I speedily surmounted them, and, after somewhat more than an hour's patient labour, succeeded in evolving the following:-- "Latitude 3 degrees 40 minutes South; longitude 139 degrees 18 minutes West. Approached from the south-west the island, at a distance of fifteen leagues, bears the exact likeness of the face of a man floating on the water. Steer for the hollow between mouth and chin, and ye shall find a river, which boldly enter, and sail up it a distance of three furlongs to the creek on starboard hand; pass into the creek and land on the island. The treasure lies buried at a spot one thousand feet due south from the base of the obelisk rock." I was so elated at this discovery, the mental relief and exhilaration were so great that, in the exuberance of my delight, I felt constrained to acquaint my friends with my success; and rushing up on the poop with the cryptogram and its rough translation in my hand, I sat down by the open skylight, close to which Sir Edgar and Lady Emily were seated, and presenting the baronet with the documents, said-- "There, Sir Edgar, read that; and never hereafter dare to assert that there is nothing in dreams!" "I do not remember that I have ever yet made the assertion," he retorted laughingly. "But do you really mean to say that you have at length mastered the secret of the cipher?" as he took the paper from me, and forthwith read it aloud for the benefit of his wife and Miss Merrivale, the latter having joined us at her sister's call. "Well," exclaimed Lady Emily, when her husband had finished, "it is really wonderful! quite the kind of thing that one reads of in books but does not believe, because one seldom or never meets with anything like it in real life. But so many strange things have happened during this eventful voyage of ours, that I shall never again be incredulous of anything."
