Pedestrianism, [William Bingley] claims, is the most 'useful' mode of travel, 'if health and strength are not wanting.' 'To a naturalist, it is evidently so; since, by this means, he is enabled to examine the country as he goes along; and when he sees occasion, he can also strike out of the road, amongst the mountains or morasses, in a manner completely independent of all those obstacles that inevitably attend the bringing of carriages or horses.' Bingley has a specific reason here for valuing the combination of freedom and intimacy with one's surroundings enjoyed by the pedestrian, but his rationale is generalisable to other travellers.
