expect to find it in connection with by far the largest mass of pitchstone in the kingdom. It is just possible, however, that Mr. Greig's two specimens may not date farther back, in at least their existing state, than the days of the hill-fort. Powerful fires would have been required to render the exposed summit of the Scuir at all comfortable; there is a deep peat-moss in its immediate neighborhood, that would have furnished the necessary fuel; the wind must have been sufficiently high on the summit to fan the embers into an intense white heat; and if it was heat but half as intense as that which was employed in fusing into one mass the thick vitrified ramparts of Craig Phadrig and Knock Farril, on the east coast, it could scarce have failed to anticipate the experiment of the Hon. Mr. Knox, of Dublin, by converting some of the numerous pitchstone fragments that lie scattered about, "into a light substance in every respect resembling pumice." It was now evening, and rarely have I witnessed a finer. The sun had declined half-way adown the western sky, and for many yards the shadow of the gigantic Scuir lay dark beneath us along the descending slope. All the rest of the island, spread out at our feet as in a map, was basking in yellow sunshine; and with its one dark shadow thrown from its one mountain-elevated wall of rock, it seemed some immense fantastical dial, with its gnomon rising tall in the midst. Far below, perched on the apex of the shadow, and half lost in the line of the penumbra, we could see two indistinct specks of black, with a dim halo around each,--specks that elongated as we arose, and contracted as we sat, and went gliding along the line as we walked. The shadows of two gnats disporting on the edge of an ordinary gnomon would have seemed vastly more important, in proportion, on the figured plane of the dial, than these, our ghostly representatives, did here. The sea, spangled in the wake of the sun with quick glancing light, stretched out its blue plain around us; and we could see included in the wide prospect, on the one hand, at once the hill-chains of Morven and Kintail, with the many intervening lochs and bold jutting headlands that give variety to the mainland; and, on the other, the variously complexioned Hebrides, from the Isle of Skye to Uist and Barra, and from Uist and Barra to Tiree and Mull. The contiguous Small Isles, Muck and Rum, lay moored immediately beside us, like vessels of the same convoy that in some secure roadstead drop anchor within hail of each other. I could willingly have lingered on the top of the Scuir until after sunset; but the minister, who, ever and anon, during the day, had been conning over some notes jotted on a paper of wonderfully scant dimensions, reminded me that this was the evening of his week-day discourse, and that we were more than a particularly rough mile from the place of meeting, and within, half an hour of the time. I took one last look of the scene ere we commenced our
