When they had walked about half an hour, still along open and waste ground of the same description, they came to the stump of an ancient oak, which, from its relics, appeared to have been at one time a tree of very large size. In an adjacent hollow they found several Highlanders, with a horse or two. They had not joined them above a few minutes, which Waverley's attendant employed, in all probability, in communicating the cause of their delay (for the words 'Duncan Duroch' were often repeated), when Duncan himself appeared, out of breath indeed, and with all the symptoms of having run for his life, but laughing, and in high spirits at the success of the stratagem by which he had baffled his pursuers. This indeed Waverley could easily conceive might be a matter of no great difficulty to the active mountaineer, who was perfectly acquainted with the ground, and traced his course with a firmness and confidence to which his pursuers must have been strangers. The alarm which he excited seemed still to continue, for a dropping shot or two were heard at a great distance, which seemed to serve as an addition to the mirth of Duncan and his comrades. The mountaineer now resumed the arms with which he had entrusted our hero, giving him to understand that the dangers of the journey were happily surmounted. Waverley was then mounted upon one of the horses, a change which the fatigue of the night and his recent illness rendered exceedingly acceptable. His portmanteau was placed on another pony, Duncan mounted a third, and they set forward at a round pace, accompanied by their escort. No other incident marked the course of that night's journey, and at the dawn of morning they attained the banks of a rapid river. The country around was at once fertile and romantic. Steep banks of wood were broken by corn-fields, which this year presented an abundant harvest, already in a great measure cut down. On the opposite bank of the river, and partly surrounded by a winding of its stream, stood a large and massive castle, the half-ruined turrets of which were already glittering in the first rays of the sun. [Footnote: See Note 2.] It was in form an oblong square, of size sufficient to contain a large court in the centre. The towers at each angle of the square rose higher than the walls of the building, and were in their turn surmounted by turrets, differing in height and irregular in shape. Upon one of these a sentinel watched, whose bonnet and plaid, streaming in the wind, declared him to be a Highlander, as a broad white ensign, which floated from another tower, announced that the garrison was held by the insurgent adherents of the House of Stuart.
