But the best way to view the mountains is to trace the Glens. To find out the glens you must often scale the shoulders of mountains, and in such journeys of discovery, you have for ever going on before your eyes glorious transfigurations. Sometimes for a whole day one mighty mass lowers before you unchanged; look at it after the interval of hours, and still the giant is one and the same. It rules the region, subjecting all other altitudes to its sway, though many of them range away to a great distance; and at sunset retains it supremacy, blazing almost like a volcano with fiery clouds. Your line of journey lies, perhaps, some two thousand feet above the level of the sea, and seldom dips down to one thousand; and these are the heights from which all above and all below you looks most magnificent, for both regions have their full power over you—the unscaleable cliffs, the unfathomable abysses—and you know not which is the more sublime. The sublimity indeed is one. It is then that you may do well to ascend to the very mountain-top. For it may happen to be one of those heavenly days indeed, when the whole Highlands seem to be reposing in the cloudless sky.
But we were about to speak of the Glens. And some of them are best entered by such descents as these—perhaps at their very head—where all at once you are in another world, how still, how gloomy, how profound! An hour ago and the eye of the eagle had not wider command of earth, sea, and sky, than yours—almost blinded now by the superincumbent precipices that imprison you, and seem to shut you out from life.
"Such the grim desolation, where Ben-Hun
And Craig-na-Torr, by earthquake shatterings
Disjoined with horrid chasms prerupt, enclose
What superstition calls the Glen of Ghosts."
Or you may enter some great glen from the foot, where it widens into vale or strath—and there are many such—and some into which you can sail up an arm of the sea. For a while it partakes of the cultivated beauty of the lowlands, and glen and vale seem almost one and the same; but gradually it undergoes a strange wild change of character, and in a few miles that similitude is lost. There is little or no arable ground here; but the pasture is rich on the unenclosed plain—and here and there are enclosures, near the few houses or huts standing, some of them in the middle of the glen, quite exposed, on eminences above reach of the floods—some more happily placed on the edge of the coppices, that sprinkle the steep sides of the hills, yet barely mountains. But mountains they soon become; and leaving behind you those few barren habitations, you see before you a wide black moor. Beautiful hitherto had been the river, for a river you had inclined to think it, long after it had narrowed into a stream, with many a waterfall, and in one chasm a cataract. But the torrent now has a wild mountain cry, and though there is still beauty on its banks, they are bare of all trees, now swelling into multitudes of low green knolls among the heather, now composed but of heather and rocks. Through the very middle of the black moor it flows, yet are its waters clear, for all is not moss, and it seems to wind its way where there is nothing to pollute its purity, or tame its lustre. 'Tis a solitary scene, but still sweet; the mountains are of great magnitude, but they are not precipitous; vast herds of cattle are browsing there, on heights from which fire has cleared the heather, and wide ranges of greensward upon the lofty gloom seem to lie in perpetual light.
The moor is crossed, and you prepare to scale the mountain in front, for you imagine the torrent by your side flows from a tarn in yonder cove, and forms that series of waterfalls. You have been all along well pleased with the glen, and here at the head, though there is a want of cliffs of the highest class, you feel nevertheless that it has a character of grandeur. Looking westward, you are astounded to see them ranging away on either side of another reach of the glen, terrific in their height, but in their formation beautiful, for like the walls of some vast temple they stand, roofed with sky. Yet are they but as a portal or gateway of the glen. For entering in with awe, that deepens, as you advance, almost into dread, you behold, beyond, mountains that carry their cliffs up into the clouds, seamed with chasms, and hollowed out into coves, where night dwells visibly by the side of day; and still the glen seems winding on beneath a purple light, that almost looks like gloom; such vast forms and such prodigious colours, and such utter stillness, become oppressive to your very life, and you wish that some human being were by, to relieve, by his mere presence, the insupportable weight of such a solitude.
But we should never have done were we to attempt to sketch, however slightly, the character of all the different kinds of glens. Some are sublime in their prodigious depth and vast extent, and would be felt to be so, even were the mountains that enclose them of no great majesty; but these are all of the highest order, and sometimes are seen from below to the very cairns on their summits. Now we walk along a reach, between astonishing ranges of cliffs, among large heaps of rocks—not a tree—scarcely a shrub—no herbage—the very heather blasted—all lifelessness and desolation. The glen gradually grows less and less horrid, and though its sides are seamed with clefts and chasms, in the gloom there are places for the sunshine, and there is felt to be even beauty in the repose. Descends suddenly on either side a steep slope of hanging wood, and we find ourselves among verdant mounds, and knolls, and waterfalls. We come then into what seems of old to have been a forest. Here and there a stately pine survives, but the rest are all skeletons; and now the glen widens, and widens, yet ceases not to be profound, for several high mountains enclose a plain on which armies might encamp, and castellated clouds hang round the heights of the glorious amphitheatre, while the sky-roof is clear, and as if in its centre, the refulgent sun. 'Tis the plain called "The Meeting of the Glens." From the east and the west, the north and the south, they come like rivers into the sea.
Other glens there are, as long, but not so profound, nor so grandly composed; yet they too conduct us nobly in among the mountains, and up their sides, and on even to their very summits. Such are the glens of Atholl, in the neighbourhood of Ben-y-gloe. From them the heather is not wholly banished, and the fire has left a green light without quenching the purple colour native to the hills. We think that we almost remember the time when those glens were in many places sprinkled with huts, and all animated with human life. Now they are solitary; and you may walk from sunrise till sunset without seeing a single soul. For a hundred thousand acres have there been changed into a forest, for sake of the pastime, indeed, which was dear of old to chieftains and kings. Vast herds of red-deer are there, for they herd in thousands—yet may you wander for days over the boundless waste, nor once be startled by one stag bounding by. Yet may a herd, a thousand strong, be drawn up, as in battle array, on the cliffs above your head. For they will long stand motionless, at gaze, when danger is in the wind—and then their antlers to unpractised eyes seem but boughs grotesque, or are invisible; and when all at once, with one accord, at signal from the stag, whom they obey, they wheel off towards the Corries, you think it but thunder, and look up to the clouds. Fortunate if you see such a sight once in your life. Once only have we seen it; and it was, of a sudden, all by ourselves,
"Ere yet the hunter's startling horn was heard
Upon the golden hills."
Almost within rifle-shot, the herd occupied a position, high up indeed, but below several ridges of rocks, running parallel for a long distance, with slopes between of sward and heather. Standing still, they seemed to extend about a quarter of a mile, and as with a loud clattering of hoofs and antlers, they took more open order, the line at least doubled its length, and the whole mountain-side seemed alive. They might not be going at full speed, but the pace was equal to that of any charge of cavalry; and once and again the flight passed before us, till it overcame the ridges, and then deploying round the shoulder of the mountain, disappeared, without dust or noise, into the blue light of another glen.
We question, if there be in the Highlands any one glen comparable with Borrowdale in Cumberland. But there are several that approach it, in that combination of beauty and grandeur, which perhaps no other scene equals in all the world. The "Gorge" of that Dale exhibits the finest imaginable assemblage of rocks and rocky hills, all wildly wooded; beyond them, yet before we have entered into the Dale, the Pass widens, with noble cliffs on one side, and on the other a sylvan stream, not without its abysses; and we see before us some lovely hills, on which—
