So I retraced my steps, intending to see if there was any other branch nearer to the sea. I kept the line taut so that Marjory might not be alarmed. I think I was as glad as she was when I saw the light through the opening, and the black circle of her head as she looked down eagerly. When underneath, I told her of my adventure, and then turned seawards to follow the cave down. The floor here was more even, as though it had been worn smooth by sea wash and the endless rolling of pebbles. The water deepened only a few inches in all. As I went, I threw the rays of my lamp around, anxiously looking for some opening. The whole distance from the place where I had made the entry to the face of the cliff was not very great; but distance in the open seems very different from that within an unknown cavern. Presently I came to a place where the floor of the cave was strewn with stones, which grew bigger and more as I went on; till at last I was climbing up a rising pile of rocks. It was slippery work, for there seemed some kind of ooze or slime over the stones which made progress difficult. When I had climbed up about half way towards the roof, I noticed that on my left side the slope began to fall away. I moved over and raising my lamp saw to my inexpressible joy that there was an opening in the rock. Getting close I found that though it was nearly blocked with stones there was still a space large enough to creep through. Also with pleasure I saw that the stones here were small. With a very slight effort I dislodged some of them and sent them rolling down, thus clearing the way. The clatter of the stones evidently alarmed Marjory for I heard her calling to me. I hurried back under the opening--the way seemed easy enough now I knew it--and told her of my fresh discovery.
