And in the Highlands from Stirling to Inverness what magic, what changing colours and shadows there were on the age-worn treeless hills, and in the valleys with their clear, pure streams receiving tribute from unnumbered little rills and springs, some dropping water drop by drop as though it were fairy-distilled; and everywhere the heather giving to the mountain-landscape a hue of rich purplish-brown, and to the air an odour of aromatic fragrance. On to the north-west beyond Inverness there is the same kind of a treeless highland country; and then after a few hours of travel one looks out across the water from Kyle and beholds Skye, where Cuchulainn is by some believed to have passed his young manhood learning feats of arms from fairy women,--Skye, dark, mountainous, majestic, with its waterfalls turning to white spray as they tumble from cliff to cliff into the sound, from out the clouds that hide their mountain-summit sources. In the Outer Hebrides, as in the Aranmore Islands off West Ireland, influences are at work on the Celtic imagination quite different from those in Skye and its neighbouring islands. Mountainous billows which have travelled from afar out of the mysterious watery waste find their first impediment on the west of these isolated Hebridean isles, and they fling themselves like mad things in full fury against the wild rocky islets fringing the coast. White spray flashes in unearthly forms over the highest cliff, and the unrestrained hurricane whirls it far inland. Ocean's eternally murmuring sounds set up a responsive vibration in the soul of the peasant, as he in solitude drives home his flocks amid the weird gloaming at the end of a December day; and, later, when he sits brooding in his humble cottage at night, in the fitful flickering of a peat fire, he has a mystic consciousness that deep down in his being there is a more divine music compared with which that of external nature is but a symbol and an echo; and, as he stirs the glowing peat-embers, phantoms from an irretrievable past seem to be sitting with him on the edge of the half-circle of dying light. Maybe there are skin-clad huntsmen of the sea and land, with spears and knives of bone and flint and shaggy sleeping dogs, or fearless sea-rovers resting wearily on shields of brilliant bronze, or maybe Celtic warriors fierce and bold; and then he understands that his past and his present are one.
