"I can conceive of only one way of traveling that is more agreeable than going by horse. That is going by foot. The traveler leaves at his own good time; he stops at will; he takes as much or as little exercise as he wants. He observes the whole country; he turns aside to the right or the left; he examines all that appeals to him; he stops to see all the views. Do I notice a river? I walk along it. A thick wood? I go beneath its shade. A grotto? I visit it. A quarry? I examine the minerals. Every- where I enjoy myself, I stay. The moment I get bored, I go. I depend on neither horse nor coachman. I do not need to choose ready-made paths, comfortable roads; I pass wherever a man can pass. I see all that a man can see; and, depending only on myself, I enjoy all the liberty a man can enjoy."
"How many different pleasures are brought together by this agreeable way of traveling, without counting strengthened health and brightened humor! I have always observed that those who traveled in good, smooth-riding vehicles were dreamy, sad, scolding, or ailing, while pedestrians were gay, easygoing, and content with everything. How the heart laughs when one approaches lodgings! How savory a coarse meal appears! With what pleasure one rests at the table! What a good sleep one has in a bad bed! When one wants only to arrive, one can hurry in a post-chaise. But when one wants to travel, one has to go on foot."
