A Highland scene is, beyond dispute, pleasant enough in its own way; but, looked close at, has its shadows. Here, for instance, is the very fact of one, as pretty as I can remember--having seen many. It is a little valley of soft turf, enclosed in its narrow oval by jutting rocks and broad flakes of nodding fern. From one side of it to the other winds, serpentine, a clear brown stream, dropping into quicker ripple as it reaches the end of the oval field, and then, first islanding a purple and white rock with an amber pool, it dashes away into a narrow fall of foam under a thicket of mountain-ash and alder. The autumn sun, low, but clear, shines on the scarlet ash-berries and on the golden birch-leaves, which, fallen here and there, when the breeze has not caught them, rest quiet in the crannies of the purple rock. Beside the rock, in the hollow under the thicket, the carcass of a ewe, drowned in the last flood, lies nearly bare to the bone, its white ribs protruding through the skin, raven-torn; and the rags of its wool still flickering from the branches that first stayed it as the stream swept it down. A little lower, the current plunges, roaring, into a circular chasm like a well, surrounded on three sides by a chimney-like hollowness of polished rock, down which the foam slips in detached snowflakes. Round the edges of the pool beneath, the water circles slowly, like black oil; a little butterfly lies on its back, its wings glued to one of the eddies, its limbs feebly quivering; a fish rises and it is gone. Lower down the stream, I can just see, over a knoll, the green and damp turf roofs of four or five hovels, built at the edge of a morass, which is trodden by the cattle into a black Slough of Despond at their doors, and traversed by a few ill-set stepping-stones, with here and there a flat slab on the tops, where they have sunk out of sight; and at the turn of the brook I see a man fishing, with a boy and a dog--a picturesque and pretty group enough certainly, if they had not been there all day starving.
