It is in the gentleness of ascent in many of the Highland hills, in the restraint and repose of the slopes 'full of slumber,' that we can trace all the finer and more delicate human lines; and it is due to the strength of these lines that the bigger mountains seem to rise without an effort from the moors and smaller hills that surround them. To many people the Cairngorm range is composed of shapeless, flat-topped mountains devoid almost of any character. They do not rise like the Matterhorn in savage grandeur, yet the sculptured sides of Braeriach, seen from Sgoran Dubh Mhor, are in reality far more full of rich and intricate mountain sculpture, than the whole face of the Matterhorn as seen from the Riffel Alp. The individuality of the Coolin is not seen in their summits, which are often almost ugly, but in the colour of the rocks, the atmospheric effects, the relative largeness and harmony of the details compared with the actual size of the mountains, and most of all in the mountain mystery that wraps them round: not the mystery of clearness such as is seen in the Alps and Himalaya, where range after range recedes into the infinite distance, till the white snow peaks cannot be distinguished from the clouds, but in the secret beauty born of the mists, the rain, and the sunshine, in a quiet and untroubled land, no longer vexed by the more rude and violent manifestations of the active powers of Nature. Once there was a time when these peaks were the centre of a great cataclysm; they are the shattered remains of a vast volcano that ages since poured its lavas in mighty flood far and wide over the land; since then the glaciers in prehistoric times have polished and worn down the corries and the valley floors, leaving scars and wounds everywhere as a testimony of this power; but the fire age and the ice age are past; now the still, clear waters of Coruisk ripple in the breeze, by the lochside lie the fallen masses of the hills, and the shattered debris left by the glaciers of bygone days; these harbour the dwarf hazel, the purple heather, and the wildflowers, whilst corrie, glen, and mountain-side bask in the summer sunlight.
