We travellers are in very hard circumstances: If we say nothing but what has been said before us, we are dull, and we have observed nothing. If we tell any thing new, we are laughed at as fabulous and romantic, not allowing either for the difference of ranks, which affords difference of company, or more curiosity, or the change of customs, that happen every twenty years in every country. But the truth is, people judge of travellers, exactly with the same candour, good nature, and impartiality, they judge of their neighbours upon all occasions.
