Before Gray crossed the Dee at Kelton, there came over the scenery a dense white mist, which rolled like smoke along the hills, and hung in dewdrops on his horse's mane and bridle, dimming the brightness of his armour and the embroidery of his surcoat. In this obscurity he lost his way amid the waste muirlands which the road, a mere bridle-path destitute of wall or fence, traversed. Then a sharp shower of hail fell, the stones rattling on his steel trappings as on a latticed window; and through the openings in the haze, the far-stretching dells and pastoral hills of Galloway seemed wet and grey and dreary. The country was singularly desolate; he met no person to direct him; thus, amid the obscurity of the mist and the approaching evening, he knew not where he was, but continued to ride slowly and vaguely on. Anon a breeze came, and the grey clouds began to disperse; the hail ceased, and the haze rolled away like finely-carded wool along the sides of the hills. The setting sun of August beamed forth in his farewell splendour, the mavis and merle chorused merrily in the sauch and hawthorn trees; for a time the hill-tops became green, and the high corn that waved on the upland slopes seemed to brighten with the partial heat and moisture. After a time, Sir Patrick found that he had penetrated to the border of Glenkens, then the wildest and most savage part of Galloway. Wheeling round his horse, he rode fast in the direction from whence he had come, and just as the sun's broad disc began to dip behind the grassy hills, and to shed its warm light upon the windings of the Dee, from an eminence he could see afar off the vast square keep of Thrave looming black and sombre, with the dusky smoke ascending from its great chimney-stalks into the calm sky in steady columns, unbroken by the breeze. Soft was the evening light, and softer now the air, and no sound but the occasional lowing of the black cattle, or those nameless country noises which seem to come from afar, broke the stillness of the vast pastoral landscape. The Dee has all the characteristics of a Scottish stream: now gliding stealthily and sullenly through deep pools and dark rocky chasms, where the wiry pine, the crisp-leaved oak, and the feathery silver birch cast their shadows on the darting trout or the lurking salmon; now chafing and brawling in white foam over a precipitous ledge of red sandstone, then gurgling down a bed of "unnumbered pebbles;" and now sweeping broad and stilly past a thatched clachan, a baron's moated tower, a ruined chapel, where bells were rung and masses said when Alan was lord of Galloway and constable of Scotland; then round some statelier fane like Tongland, or a vast feudal strength like Thrave of the Douglases.
