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.

Then I went back again and climbed down the slope of fallen stones; this was evidently the debris of the explosion which had choked the mouth of the cave. The new passage trended away a little to the right, making a sharp angle with the cave I had left. Then after deflecting to the left it went on almost straight for a considerable distance, thus lying, as I made it out, almost parallel to the first cave. I had very little anxiety as to the safety of the way. The floor seemed more level than even that of the entrance to the first cave. There was a couple of feet of water in the deepest part, but not more; it would not have been difficult to carry the treasure here. About two hundred feet in, the cave forked, one arm bending slightly to the left and the other to the right. I tried the former way and came to a sheer dip in the rock such as I had met with before. Accordingly I came back and tried the second. When I had gone on a little way, I found my line running out; so I went back and asked Marjory to throw me down the end. I was so sure of the road now that I did not need a clue. At first she demurred, but I convinced her; taking the rope I fixed one end of it within the cave before it branched. Then I started afresh on my way, carrying the coil of rope with me.
