mist lies thick in the hollows, an occasional glimpse may be caught of it even by day. But when I passed the way there was no fog: the light, though softened by a thin film of cloud, fell equally over the heath, revealing hill and hollow; and I was unlucky enough not to see this goblin of the Liasic valley. A deep indentation of the coast, which forms the bay of Broadford, corresponds with the hollow of the valley. It is simply a portion of the valley itself occupied by the sea; and we find the Lias, from its lower to its upper beds, exposed in unbroken series along the beach. In the middle of the opening lies the green level island of Pabba, altogether composed of this formation, and which, differing, in consequence, both in outline and color, from every neighboring island and hill, seems a little bit of flat fertile England, laid down, as if for contrast's sake, amid the wild rough Hebrides. Of Pabba and its wonders, however, more anon. I explored a considerable range of shore along the bay; but as I made it the subject of two after explorations ere I mastered its deposits, I shall defer my description till a subsequent chapter. It was late this evening ere the post-gig arrived from the south, and the night and several hours of the following morning were spent in travelling to Portree. I know not, however, that I could have seen some of the wildest and most desolate tracts in Skye to greater advantage. There was light enough to show the bold outlines of the hills,--lofty, abrupt, pyramidal,--just such hills, both in form and grouping, as a profile in black showed best; a low blue vapor slept in the calm over the marshes at their feet; the sea, smooth as glass, reflected the dusk twilight gleam in the north, revealing the narrow sounds and deep mountain-girdled lochs along which we passed; gray crags gleamed dimly on the sight; birch-feathered acclivities presented against sea and sky their rough bristly edges; all was vast, dreamy, obscure, like one of Martin's darker pictures: the land of the seer and the spectre could not have been better seen. Morning broke dim and gray, while we were yet several miles from Portree; and I reached the inn in time to see from my bed-room windows the first rays of the rising sun gleaming on the hill-tops.
