It issued in a narrow glen, between two mountains, both very lofty, and covered with heath. The brook continued to be their companion, and they advanced up its mazes, crossing them now and then, on which occasions Even Dhu uniformly offered the assistance of his attendants to carry over Edward; but our hero, who had been always a tolerable pedestrian, declined the accommodation, and obviously rose in his guide's opinion by showing that he did not fear wetting his feet. Indeed he was anxious, so far as he could without affectation, to remove the opinion which Evan seemed to entertain of the effeminacy of the Lowlanders, and particularly of the English. Through the gorge of this glen they found access to a black bog, of tremendous extent, full of large pit-holes, which they traversed with great difficulty and some danger, by tracks which no one but a Highlander could have followed. The path itself, or rather the portion of more solid ground on which the travellers half walked, half waded, was rough, broken, and in many places quaggy and unsound. Sometimes the ground was so completely unsafe, that it was necessary to spring from one hillock to another, the space between being incapable of bearing the human weight. This was an easy matter to the Highlanders, who wore thin-soled brogues fit for the purpose, and moved with a peculiar springing step; but Edward began to find the exercise, to which he was unaccustomed, more fatiguing than he expected. The lingering twilight served to show them through this Serbonian bog, but deserted them almost totally at the bottom of a steep and very stony hill, which it was the travellers' next toilsome task to ascend. The night, however, was pleasant, and not dark; and Waverley, calling up mental energy to support personal fatigue, held on his march gallantly, though envying in his heart his Highland attendants, who continued, without a symptom of abated vigour, the rapid and swinging pace, or rather trot, which, according to his computation, had already brought them fifteen miles upon their journey.
