Greene Ferne Farm by Richard Jefferies

When Geoffrey felt certain that she was sleeping, his next care was to examine the exterior of the Cave, thinking that there might probably be openings between the stones that would admit a draught. The hurdle at the doorway, full of minute interstices, and purposely placed loosely, allowed sufficient air to enter for breathing; what he wished to prevent was a current crossing the chamber, for though warm then, towards the morning the atmosphere is usually cooler. He found that in the course of the centuries the ground had risen materially, so that the floor inside the cave was below the level of the sward without. This partially closed the crevices between the rude slabs, and from the raised turf grasses had grown thickly, and filled the remaining space except in one spot. There the boulder wall, settling under the weight of the capstone, leaned somewhat from the perpendicular and left a wide chink. With his knife he cut a broad sod of turf, and placed it against the aperture, grass side inwards, filling it up completely. Then, stepping lightly that he might not wake her, he sought the horses, and relieved them of their bridles, feeling certain that they would not wander far. A few yards from the copse there was a slight incline of the ground; there he sat down on the sward near enough to hear Margaret in a moment should she call.

Now that his labour was over and the excitement had subsided, even his powerful frame felt the effect of unusual exertion -- besides riding, he had run and walked many miles that night. Presently he involuntarily reclined almost at full length, leaning on one arm; his weight crushed a thick bunch of wild thyme that emitted a delicious scent. Tall dry bennets and some low bushy heath grew at his side. On the left hand -- eastwards -- stood a hawthorn bush; in front -- southwards -- was a deep coombe, and beyond that a steep Down, towards the top of which grew a few gaunt and scattered firs. As the moon swept slowly higher the pale light fell upon the boulders and the dolmen as it had fallen for so many ages past. The darkness in the deep valley became more intense as the shadow of the hill grew more defined; where the moonlight fell upon the slopes they shone with a greenish-grey reflection, which, when looked at intently, vanished.
