"Let us go into the old chapel. I haven't had a good look at it since I have been coming here!" So we went into the chapel and began to lay our traps. Of course we could not guard against any one spying upon us. There might be eyes of enemies bent on us through some secret chink or cranny or organised spy-hole. This we could not help, and had to take our chances of it; but if anyone were within ear-shot and unable to see us, we guarded our movements by our misleading remarks concerning history and art. Deftly Marjory stretched sections of her gossamer thread from place to place, so that if any one went in the chapel their course must be marked by the broken threads. We finished near the door, and our artless, innocent, archæological conversation stopped there, too. We strolled back to the castle, feeling sure that if there were any secret hiding place within the ruin we should have located the entrance to it in the morning. That afternoon I went to the house at Whinnyfold. Most of the things which I had ordered had arrived, and when I had had the various boxes and bundles moved inside I felt able to start on my work. First I rigged up a proper windlass over the hole into the cave; and fixed it so that any one could manipulate it easily and safely from above. It could be also worked from below by aid of an endless chain round the axle. I hammered the edges of the hole somewhat smoother, so that no chance friction might cut the rope; and I fixed candles and lanterns in various places, so that all the light which might be necessary could be had easily. Then I furnished a room with rugs and pillows, and with clothes for Marjory for changing. She would be sure to require such, when our search after the treasure should come off. I had ready some tins of provisions, and I had arranged at the hotel that as I might sometimes stay and work in my own home--I was supposed to be an author--some fresh provisions were to be sent over each morning, and left ready for me with Mrs. Hay at Whinnyfold. By the time my work was through, it was late in the evening, and I went to the hotel to sleep. I had arranged with Marjory to be with her early in the morning. It was hardly daylight when I woke, but I got up at once and took my way towards Crom, for the experience of the day before had shown me that whoever used the path near the monument used it in the grey of the dawn. As usual I hid my bicycle and took my way cautiously to the monument. By this time the sun was up and the day was bright; the dew lay heavy, and when I came on any of my threads I could easily distinguish them by the shimmering beads which made each thread look like a miniature rope of diamonds.
