Presently we found that our boat was being left high and dry, the water ebbing swiftly away from us towards the mouth of the cave. We had, as it happened, entered at the height of the tide, and now the water was upon the turn. But this affected us little, for we judged that either it would go so far back that we might find a way of escape by clambering over the rocks out upon the land; or else, at the worst, we knew that, by waiting till the next tide, we should be able to return the way we had come. At all events, for that time at least, we thought ourselves to have outwitted our pursuers and to stand no longer in their danger. But we were briskly to learn another way of it, for the oftenest slip is made upon the threshold of safety. Marjorie and Nell bore themselves through all these dangers and discomforts with the greatest courage. Never had this come home to me so strongly before, for the maid’s shamefacedness had died out of Marjorie Kennedy; and now she seemed wholly set with a fierce jealousy of hate to compass the punishment of her father’s enemies. The water being in this manner retired, and our boat lying high and dry upon a shelving beach, I proposed that the Dominie and myself should attempt some exploration of the place where we found ourselves—while we left Nell and her sister by the boat to make such dispositions of their cleading as would countervale the discomfort of Marjorie’s rescue from death. So the Dominie and I felt with our hands all round the wide amphitheatre which had so lately been filled with the salt water. We had no difficulty in discovering the narrow passage by which we had come, for down its narrow gullet the water was now retreating with great swiftness. But we seemed to be at the sack’s end in every other way, so that we looked for nothing else but having to return to the same place, and in the same way by which we came, after our enemies had retired. So swiftly did the tide run back, that it seemed as if it might be possible for us to walk out upon our own feet. And so indeed we did, but in a very strange fashion. For in one of my gropings I came upon a projection of the rock, which caught my foot and threw me forward upon my face. As I fell, my hands touched something like a flight of rough steps which led up from the sanded floor of the cavern. Without waiting to call out to Dominie Mure I mounted, with my heart beating fast with anticipation, and at the top I came into a narrower passage than any we had yet entered, which led me forward a long way. As I went the air felt unaccountably lighter. It smelled most like a well-fired room, dry and pleasant, so that I waited only to ascertain that the passage ended in another apartment before going back to communicate my fortunate discovery to Marjorie and Nell.
