Suppose he could take one meal so compact and comprehensive that he should never hunger any more; suppose him, at a glance, to take in all the features of the world and allay the desire for knowledge; suppose him to do the like in any province of experience - would not that man be in a poor way for amusement ever after?

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.

参考译文:
