The rock of the hill was slaty. The strata ran down and made a dip and came to the surface again, and in the lap lay the limestone. When the quarry-men had deserted the old workings, water came in and partly filled it, to the depth of forty feet, with crystalline bottle-green water. Lord Lamerton had put in trout, and the fish grew there to a great size, but were too wary to be caught. The side of the quarry to the south shelved rapidly into the water, and the fisherman standing on the slope with his rod was visible to the trout. They were too cautious to approach, and too well fed with the midges that hovered over the water to care to bite. The north face of the quarry—that is the face that looked to the sun—was quite precipitous; it rose to the same height above the water that it descended beneath it. Over the edge hung bushes of may that wreathed the gray rocks in spring with snow as of the past winter, and in winter with scarlet berries, reminiscences of the fire of lost summer. Where the may-bushes did not monopolise the top, there the heath and heather hung their wiry branches and grew to brakes, and the whortleberry—the vaccinium—formed a fringe of glossy leafage in June and July rich with purple berries, and in autumn dotted with fantastic scarlet, where a capricious leaf had caught a touch of frost that had spared its fellows. Down a rocky cranny fell a dribbling stream, the drainage of the wood above; in summer it was but a distillation, sufficient to moisten the beds of moss and fern that rankly grew on the ledges beneath it, and in winter never attaining sufficient volume to dislodge the vegetation it nourished. To the ledges thus moistened choice ferns had retreated as to cities of refuge from the rapacity of collectors, who rive away these delicate creatures regardless what damage is done them, indifferent whether they kill in the process, considering only the packing of them off in hampers for sale or barter, and in many places exterminating the rarest and most graceful ferns; but here, with a gulf of deep water between themselves and their pursuers, the parsley and maiden-hair ferns throve and tossed their fronds in security and insolence. It was marvellous to see how plants luxuriated in this old abandoned quarry, how they seized on it, as squatters on no-man’s land, and multiplied and grew wanton and revelled there; how the harts tongue grew there to enormous size, and remained, unbrowned by frost, throughout the winter; how the crane’s bill bloomed to Christmas, and scented the air around, and the strawberry fruited out of season and reason.
