The westward route being continued by the side of the river, we walk through _Shad Thames_ and _Pickle Herring Street_ (underneath an archway) to _Vine Street_, where is the southern entrance of the _Tower Subway_, by which we may cross below the river to the other side. Emerging near the Tower, Quilp’s House, on Tower Hill, is near at hand. No. 6 Tower Dock, facing the public entrance to the Tower, is said to have comprised the lodging assigned by Dickens for the accommodation of Mr. and Mrs. Daniel Quilp and Mrs. Jiniwin. We may here recall the matrons’ tea-meeting, as described in chapter 4 of “The Old Curiosity Shop,” when Quilp’s conduct as a husband was freely discussed, and much good advice tendered to Mrs. Quilp for the true assertion of her rights and dignity. Also the notable occasion when, the master of the house being missing and thought to be drowned, _Mr. Sampson Brass_ was in consultation, and the party were unpleasantly surprised, as they were preparing a descriptive advertisement, by the sudden appearance of the Dwarf, as lively and sarcastic as ever. “A question now arises with regard to his nose. ‘Flat,’ said Mrs. Jiniwin. ‘Aquiline!’ cried Quilp, thrusting in his head, and striking the feature with his fist. ‘Aquiline, you hag. Do you see it? Do you call this flat? Do you? Eh?’” Hard by this locality stands Trinity House, Tower Hill, with its garden in front, and it may be remembered that _Mr. Wilfer_ suggested this neighbourhood as a waiting-place for Bella, on the occasion of their “innocent elopement” to Greenwich, while he should array himself in new garments at her expense, to do honour to the expedition. We now turn westward by _Tower Street_, and may save time by taking train at _Mark Lane Station_ for the Mansion House, about ten minutes’ ride. On arrival at the Mansion House Station we shall find _Queen Street_ close at hand, leading riverwards to Southwark Bridge, referred to in “Little Dorrit” as the Iron Bridge. This was Amy Dorrit’s favourite promenade, it being quieter than many of the neighbouring thoroughfares; and we may recall the scene when young _John Chivery_ was obliged to take no for an answer, when he attempted the proffer of his hand and heart. Proceeding onwards through _Cannon Street_, we turn to the right through _St. Paul’s Churchyard_, crossing Cheapside to the stately edifice of the General Post Office, _St. Martin’s-le-Grand_. This building, in the times of “Nicholas Nickleby,” occasioned honest John Browdie some surprise:— “Wa-at dost thee tak’ yon place to be, noo, that ’un ower the wa’? Ye’d never coom near it, gin ye thried for twolve moonths. It’s na but a Poast-office. Ho, ho! they need to charge for double latthers. A Poast-office! What dost thee think of that? Ecod, if that’s on’y a Poast-office, loike to see where the Lord Mayor o’ Lunnon lives!”
