Another photograph—evidently a time-exposure taken in deep shadow—was of the mouth of a woodland cave, with a boulder of rounded regularity choking the aperture. On the bare ground in front of it, one could just discern a dense network of curious tracks, and when I studied the picture with a magnifier I felt uneasily sure that the tracks were like the one in the other view. A third picture showed a druid-like circle of standing stones on the summit of a wild hill. Around the cryptic circle the grass was very much beaten down and worn away, though I could not detect any footprints even with the glass. The extreme remoteness of the place was apparent from the veritable sea of tenantless mountains which formed the background and stretched away toward a misty horizon.
