The first two or three miles were rather melancholy, from want of the society to which he had of late been accustomed. But this unusual mood of mind soon gave way to the influence of his natural good spirits, excited by the exercise and the bracing effects of the frosty air. He whistled as he went along, not 'from want of thought,' but to give vent to those buoyant feelings which he had no other mode of expressing. For each peasant whom he chanced to meet he had a kind greeting or a good-humoured jest; the hardy Cumbrians grinned as they passed, and said, 'That's a kind heart, God bless un!' and the market-girl looked more than once over her shoulder at the athletic form, which corresponded so well with the frank and blythe address of the stranger. A rough terrier dog, his constant companion, who rivalled his master in glee, scampered at large in a thousand wheels round the heath, and came back to jump up on him and assure him that he participated in the pleasure of the journey. Dr. Johnson thought life had few things better than the excitation produced by being whirled rapidly along in a post-chaise; but he who has in youth experienced the confident and independent feeling of a stout pedestrian in an interesting country, and during fine weather, will hold the taste of the great moralist cheap in comparison. Part of Brown's view in choosing that unusual track which leads through the eastern wilds of Cumberland into Scotland, had been a desire to view the remains of the celebrated Roman Wall, which are more visible in that direction than in any other part of its extent. His education had been imperfect and desultory; but neither the busy scenes in which he had been engaged, nor the pleasures of youth, nor the precarious state of his own circumstances, had diverted him from the task of mental improvement. 'And this then is the Roman Wall,' he said, scrambling up to a height which commanded the course of that celebrated work of antiquity. 'What a people! whose labours, even at this extremity of their empire, comprehended such space, and were executed upon a scale of such grandeur! In future ages, when the science of war shall have changed, how few traces will exist of the labours of Vauban and Coehorn, while this wonderful people's remains will even then continue to interest and astonish posterity! Their fortifications, their aqueducts, their theatres, their fountains, all their public works, bear the grave, solid, and majestic character of their language; while our modern labours, like our modern tongues, seem but constructed out of their fragments.' Having thus moralised, he remembered that he was hungry, and pursued his walk to a small public-house, at which he proposed to get some refreshment.
