Arriving at _Spa Road_, the explorer turns left and right by the short routes of _West Street South_, _Fream Street_, and _Rouel Road_, into _Jamaica Road_ (five minutes from station); passing from the opposite side of which, through _Parker’s Row_ to the thoroughfare of _Dockhead_, he will find himself face to face with a tavern on the north side, named “The Swan and Sugar Loaf.” A short cut on the right of this house leads immediately to LONDON STREET, its northern side forming the south boundary of the old site of Jacob’s Island. _Folly Ditch_, flowing from the Thames through Mill Street, took its course through London Street (it has been filled in since 1851); and in these streets wooden bridges crossed to the Island, and “crazy wooden galleries, common to the backs of half-a-dozen houses”—referred to by the novelist—used to “ornament the banks of Folly Ditch.” To the right we pass into _George Row_, enclosing Jacob’s Island (east), and may note _en passant_ the blocks of workmen’s dwellings, erected 1883, named “Wolseley’s Buildings,” which occupy the site of the old Island on its eastern side. From George Row we turn (right) into _Jacob Street_, north of the Island, by which we come into _Mill Street_ (west); again returning to _London Street_, and so completing the circumnavigation of this interesting locality. Some of the old wooden erections still exist in _Farthing Alley_, _Halfpenny Alley_, and _Edward Street_, which intersect the area. In his preface to the first cheap edition of “Oliver Twist,” the author makes a further reference, as follows:— “In the year one thousand eight hundred and fifty, it was publicly declared in London by an amazing alderman, that Jacob’s Island did not exist, and never had existed. Jacob’s Island continues to exist (like an ill-bred place as it is) in the year one thousand eight hundred and sixty-seven, though improved and much changed.” Starting westward from “The Swan and Sugar Loaf,” we now proceed through _Thornton Street_, and turn to the right, by one block in the street beyond, into _Queen Street_, which leads directly north to the riverside. At the end of this street is the locality of Quilp’s Wharf and place of business, aforetime described in the pages of “The Old Curiosity Shop”:— “A small, rat-infested, dreary yard, in which were a little wooden counting-house, burrowing all awry in the dust as if it had fallen from the clouds, and ploughed into the ground; a few fragments of rusty anchors, several large iron rings, some piles of rotten wood, and two or three heaps of old sheet copper—crumpled, cracked, and battered.” The place has been altogether altered and improved during the last forty years, and is now known as “Butler’s Wharf,” but the original prototype of Quilp is still remembered by some of the older residents of the neighbourhood.
