Rh surface for that was an uniform thick coating of brown pine needles, but the general conformation. Where a trench has been made, there is ever after some trace of it to be found. Even if the workmen level the trench most carefully there and then, the percolation of rain through the softer broken earth will make discovery of the change by shrinkage. Here, however, there was no such sign; the ground, so far as one could judge, had never been opened. The trees grew irregularly, and there was no gap such as would be, had one ever been removed. Here and there particles of rock cropped out amongst the pine needles just as anywhere else. If any opening existed it was not on the direct line between the reservoir and the castle.

Back again I went to the reservoir, and, using it as a base, began to cast around for some opening or sign. I made circles in all directions, just as a retriever does when looking for a fallen partridge in a dry stubble when the scent is killed by heat.

At last I came upon something, though whether or no it might have any point of contact with my purpose, I could not at once decide. It was a rude monument of some kind, a boulder placed endwise on a slab of rock roughly hewn to form a sort of square plinth. This again was surrounded on the outside, for the whole monument was on the very edge of a steeply-dipping crag, by a few tiers of rough masonry. The stones were roughly cut and laid together without mortar; or if mortar or cement there had ever been, time and weather had washed it away. In one respect this structure was in contrast to that above the reservoir, there was not a sign of moss or lichen about it. The trees of the wood came close up behind it; in front it was shut out from view below by the branches of a few pine trees which grew crookedly from a precarious foothold amongst the ledges of rock beneath.
