A master hand has so often described the glens and ravines of Scotland, that it seems vain and presumptuous to meddle with them; and yet we must ask our readers to figure to themselves a sharp cleft sloping downwards to a brawling mountain stream, the sides scattered with gray rocks of every imaginable size, interspersed here and there with heather, gorse, or furze. Just in the widest part of the valley, a sort of platform of rock jutted out from the hillside, and afforded a station for one of those tall, narrow, grim-looking fastnesses that were the strength of Scotland, as well as her bane.
