couple of feet of water; but we decided to go on at once as it would give us more time if we started on a falling tide.
I took Marjory first up the passage inland, so that she might understand something of the lines of the cave system. There was, however, too much tide just then to show her where I surmised there might be some deep opening, perhaps permanently under water, into some of the other caves. Then we retraced our steps and gained the pile of debris of the explosion at the cave's mouth. I could not but notice how much Marjory was impressed by the stillness of the place. Here, the tide, filtering in by innumerable crevices and rifts between the vast pile of stones, showed no sign of the force of waves without. There was not time for the rise and fall of waves to be apparent; but the water maintained its level silently, except for that ceaseless gurgle which comes with the piling in of water anywhere, and is so constant that it does not strike one as a sound. It was borne in upon us that the wildest storm without, would make no impress upon us here in this cavern deep; and with it, as an inevitable corollary, came the depressing thought of our helplessness should aught go wrong in the fastnesses of this natural prison.
Marjory bounded over the slippery stones like a young deer, and when we passed through the natural archway into the cave beyond, her delight was manifest. She was hurrying on so quickly that I found it necessary to tell her she must go slow so as to be able to take stock of all around her as she went. It was needful to look back as well as forward, so that she might recognise the places when coming the other way. I reminded her of caution by holding up the great ball of stout cord which I carried, the end of which was attached to the rope of the windlass in the cellar. "Remember, dear," I said, "that you have to be prepared for all eventualities; if necessary to go back
