MUDFOG, Our Town, Dullborough, the Market Town, and Cloisterham were the varied names that Charles Dickens bestowed upon the "ancient city" of Rochester. Every reader of his works knows how well he loved it in early youth, and how he returned to it with increased affection during the years of his ripened wisdom. Among the first pages of the first chapter of Forster's _Life_ we find references to it:--"That childhood exaggerates what it sees, too, has he not tenderly told? How he thought that the Rochester High-street must be at least as wide as Regent Street which he afterwards discovered to be little better than a lane; how the public clock in it, supposed to be the finest clock in the world, turned out to be as moon-faced and weak a clock as a man's eyes ever saw; and how in its Town Hall, which had appeared to him once so glorious a structure that he had set it up in his mind as the model from which the genie of the Lamp built the palace for Aladdin, he had painfully to recognize a mere mean little heap of bricks, like a chapel gone demented. Yet, not so painfully either when second thoughts wisely came. 'Ah! who was I, [he says] that I should quarrel with the town for being changed to me, when I myself had come back, so changed, to it? All my early readings and early imaginations dated from this place, and I took them away so full of innocent construction and guileless belief, and I brought them back so worn and torn, so much the wiser and so much the worse!'" It would occupy too much space in this narrative to adequately give even a brief historical sketch of the City of Rochester, which is twenty-nine miles from London, situated on the river Medway, and stands on the chalk on the margin of the London basin; but we think lovers of Dickens will not object to a recapitulation of a few of the most noteworthy circumstances which have happened here, and which are not touched upon in the chapters relating to the Castle and Cathedral. According to the eminent local antiquary, Mr. Roach Smith, F.S.A., the name of the city has been thus evolved:--"The ceastre or chester is a Saxon affix to the Romano-British (DU)RO. The first two letters being dropped in sound, it became Duro or Dro, and then ROchester, and it was the Roman station Durobrovis." The ancient Britons called it "Dur-brif," and the Saxons "Hrofe-ceastre"--Horf's castle, of which appellation some people think Rochester is a corruption.
