The Thames and its wonderful glamour, its mingled beauty and squalor--beauty, in the misty distance--squalor, in the more prosaic near view--suggests memories of Dickens, as it does of Turner. Memories of that "great master of tears and laughter" are, indeed, awakened by every bend of the stream. The romance of the mighty river was all-powerful with him, as with Turner; for he, too, had known it in his early youth. To him, also, even Thames mud afforded mysterious interest. Did not the blacking factory, celebrated in the pathetic pages of _David Copperfield_, where the miserable hours of his own early youth were spent, stand at the waterside, in Blackfriars? "My favourite lounging place," says David, "in the intervals, was old London Bridge (this was before its demolition in 1832), where I was wont to sit in one of the stone recesses, watching the people going by, or to look over the balustrades at the sun shining in the water, and lighting up the golden flame on the top of the monument." The real David--poor little boy--may, indeed, have occasionally played at being a London mudlark himself, in off-hours; but this he does not tell us! "Murdstone and Grinby's warehouse was at the water side. It was down in Blackfriars. Modern improvements have altered the place; but it was the last house at the bottom of a narrow street, curving down hill to the river, with some stairs at the end, where people took boat. It was a crazy old house with a wharf of its own, abutting on the water when the tide was in, and on the mud when the tide was out, and literally overrun with rats." The waterside scenes in _The Old Curiosity Shop_, including the wharf where Mr. Quilp, the vicious dwarf, broke up his ships, and where Mr. Sampson Brass so nearly broke his shins, were rivalled in vividness, thirty years afterwards, by the river chapters in _Our Mutual Friend_. In this later story, special stress is laid on the river suicides, and the consequent "dragging" for corpses, done by the watermen for salvage. Dreadful task! but not uncommon "down by Ratcliffe, and by Rotherhithe, where accumulated scum of humanity seemed to be washed from higher ground, like so much moral sewage, and to be pausing until its own weight forced it over the bank and sunk it in the river." Near Rotherhithe--a dingy pier usually infested by mudlarks--is "Jacob's Island," made notorious by the scene in _Oliver Twist_. "It is surrounded," says Dickens, "by a muddy ditch, six or eight feet deep, and fifteen or twenty wide when the tide is in ... known in these days as Folly Ditch." By means of this ditch, the murderer Sikes tries to escape from the infuriated crowd who clamour for his life, but he fails in the attempt and perishes miserably.
