London, after the lapse of centuries, has been compared to an old ship that has been repaired and rebuilt till not one of its original timbers can be found; so marvellous are the changes and transmutations which have come over the "town upon the lake" or, harbour for ships as London was anciently called, that if a Celt, or a Roman, or a Saxon, or a Dane, or a Norman, or a Citizen of Queen Elizabeth's time were to awake from his long slumber of death, he would no more know where he was, and would be as strangely puzzled as an Englishman of the present generation would be, who had never stirred further than the radius of the Metropolis, supposing him to be conveyed by some supernatural agency one night to China, who, on rising the next morning finds himself surrounded by the street-scenery of the city of Pekin. Costumes, manners, language, inhabitants have all changed! Viewed from a geological stand-point, even the soil on which New London stands is not the same as that on which Old London stood. The level of the site of the ancient city was much lower than at present, for there are found indications of Roman highways, and floors of houses, twenty feet below the existing pathways.
