One who goes touring on foot with a single volume in his knapsack reads with circumspection, pausing often to reflect, and often laying the book down to contemplate the landscape or the prints in the inn parlour; for he fears to come to an end of his entertainment, and be left companionless on the last stages of his journey. 译文： 假如一个人一顿饭吃得紧凑而丰盛，考试大那他就不会再感到饥饿；假如一眼就能看透人间世事，他就不会再有求知的欲望。如果他在生活中其它任何领域都是如此，那他的生活还有乐趣可言吗？
一个徒步旅行的人，背包里只有一本书，他会精心的研读，不时停下来思考一番，还经常会放下书，凝视着风景，或者观赏酒馆里的装饰图案；他害怕一但读完，便没有什么乐趣了，剩下的旅程将寂寞而无以为藉。
