MOUNTAINS OF GREAT BRITAIN.

The British isles present many mountains of a bold and imposing character: when contrasted, however, with those which have been already described, they must be considered as comparatively diminutive.

BEN NEVIS.

The loftiest of these mountains is Ben Nevis, in Scotland, its elevation above the level of the sea being forty-three hundred and eighty feet, or somewhat more than four-fifths of a mile. It terminates in a point, and elevates its rugged front far above all the neighboring mountains. It is of easy ascent; and at the perpendicular hight of fifteen hundred feet, the vale beneath presents a very agreeable prospect, the vista being beautified by a diversity of bushes, shrubs, and birch woods, besides many little verdant spots. The sea and the shore are also seen.

At the summit, the view extends at once across the island, eastward toward the German sea, and westward to the Atlantic ocean. Nature here appears on a majestic scale and the vastness of the prospect engages the whole attention, at the same time the objects in view are of no common dimensions. Just over the opening of the sound, at the south-west corner of Mull, Colonsay rises out of the sea like a shade of mist, at the distance of more than ninety miles. Shuna and Lismore appear like small spots of rich verdure, and, though nearly thirty miles distant, seem quite under the spectator. The low parts of Jura can not be discerned, nor any part of Isla; far less the coast of Ireland, as has been asserted. Such is, however, the wide extent of view, that it extends one hundred and seventy miles from the horizon of the sea at the Murray frith, on the north-east, to the island of Colonsay, on the south-west.

On the north-east side of Ben Nevis is an almost perpendicular precipice, certainly not less than fourteen hundred feet in depth; probably more, as it appears to exceed the third part of the entire hight of the mountain. A stranger is astonished at the sight of this dreadful rock, which has a quantity of snow lodged in its bosom throughout the whole year. The sound of a stone thrown over the cliff to the bottom, can not be heard when it falls, so that it is impossible to ascertain in that way the hight of the precipice.

SNOWDON.

This is the loftiest of the Welch mountains, its elevation above the level of the sea being thirty-seven hundred and twenty feet, or nearly three-quarters of a mile. It is accessible on one side only, its flanks being in every other quarter precipitous. Its aspect soon convinces the spectator that he is not to look to the Alps alone, or to the rocky regions of Altai, bordering on Siberia, for romantic scenes of wildness, confusion and disorder. Snowdon presents them in all their rude and native majesty.

In the ascent, a narrow path not more than nine feet in width, leads along the margin of a frightful precipice of nearly fifteen hundred feet in extent, so perpendicular that it can not be approached without terror; while to the north of the summit nearest to the one the most elevated, a semi-amphitheater of precipitous rocks, also of a great hight, is seen; and, behind this summit, another semicircle of equal depth and extent. The loftiest summit here appears to descend in the form of a sharp ridge, and beneath it another appears, which, on account of its color, is called the Black Rock. From the upper part of the valley, one of these summits presents a grand, vertical, and very elevated point.

The bottom of each of the amphitheaters of rocks, thirteen in number, is occupied by a small lake of a circular form, and very deep. The one known by the name of Llyn Glass is remarkable for its green hue, derived from its being impregnated with copper, several mines of which line its borders. Than this mountain, nothing in the Alps can be more arid and desert, those regions alone excepted which are too lofty to admit of vegetation. Here there is not a tree, not even a shrub; small patches of verdure, which sheep can scarcely reach, are alone to be seen. Its summit, or highest peak, is a flat of about eighteen feet only in circumference. Thence may be seen a part of Ireland, a part of Scotland, Cumberland, Lancashire, Cheshire, all North Wales, the isle of Man, and the Irish and British seas, with innumerable lakes; while the whole island of Anglesea is displayed so distinctly, that, its flat uncultivated plains, bounded by the rich Parys mountain in the vicinity of Holyhead, may be descried as on a map.
