The climber will know that he is at the top of Ben Muich Dhui, when he has to scramble no longer over scaurs or ledges of rock, but walking on a gentle ascent of turf, finds a cairn at its highest part. When he stands on this cairn, he is entitled to consider himself the most elevated personage in the United Kingdom. Around it is spread something like a table-land, and one can go round the edges of the table, and look down on the floor, where the Dee, the Avon, the Lui, and many other streams, are seen like silver threads, while their forest banks resemble beds of mignionette or young boxwood. There are at several points prodigious precipices, from which one may contemplate the scene below; but we recommend caution to the adventurer, as ugly blasts sometimes sweep along the top. When a mountain is the chief of a district, we generally see from the top a wide expanse of country. Other mountains are seen, but wide valleys intervene, and thus they are carried to a graceful distance. Probably, more summits are seen from Ben Nevis, than from any other height in Scotland, but none of them press so closely on the monarch as even to tread upon his spurs. The whole view is distant and panoramic. It is quite otherwise with Ben Muich Dhui. Separated from it only by narrow valleys, which some might call mere clefts, are Cairn Toul, Brae Riach, Cairn Gorm, Ben Avon, and Ben-y-Bourd--all, we believe, ascending more than four thousand feet above the level of the sea--along with several other mountains which very closely approach that fine round number. The vicinity of some of these summits to Ben Muich Dhui has something frightful in it. Standing on the western shoulder of the hill, you imagine that you might throw a stone to the top of Brae Riach--we have been so much deceived by distance as to have seriously made the attempt, we shall not venture to say how many years ago. Yet, between these two summits rolls the river Dee; and Brae Riach presents right opposite to the hill on which we stand, a mural precipice, said to be two thousand feet high--an estimate which no one who looks on it will be inclined to doubt. Brae Riach, indeed, is unlike any thing else in Scotland. It is not properly a hill, but a long wall of precipice, extending several miles along the valley of the Dee. Even in the sunniest weather it is black as midnight, but in a few inequalities on its smooth surface, the snow lies perpetually. Seldom is the cleft between the two great summits free of clouds, which flit hither and thither, adding somewhat to the mysterious awfulness of the gulf, and seeming in their motions to cause certain deep but faint murmurs, which are in reality the mingled sounds of the many torrents which course through the glens, far, far below.
