As shown in the above print by John Leech, the rick 
  burners were impoverished, and rebelled by burning 
  ricks of hay. (This is explained in greater detail
  in the discussion of the Industrial Revolution). 
  The painting of Dickens by Augustus Egg shows an interest
  Dickens shared with others. Dickens was closely in touch 
  with John Leech, Augustus Egg, Henry Mayhew, etc.
 
 
   
     The next contradiction with Mayhew's very careful 
     reporting of a dredgerman's testimony, is Dickens' 
     introduction of Gaffer Hexam's daughter Lizzie, who 
     rows their boat as Gaffer scans the water for likely 
     items to scavenge (bodies). Lizzie expresses a view 
     that is in sharp contrast with the epitome of his life 
     given by the dredgerman in "London Labour and the 
     London Poor". It is highly unlikely that anyone 
     living from hand to mouth on the river would hold such 
     a view, but it is exactly what we would expect Charles 
     Dickens, with his bourgeois attitude, to impute to 
     others:
   
 
  .
 
   
    "Here! and give me hold of the sculls. I'll take the rest of 
    the spell."
   
   
    "No, no, father! No! I can't indeed. 
    Father!—I cannot sit so near it!"
   
   
    He was moving towards her to change places, but her 
    terrified expostulation stopped him and he resumed 
    his seat.
    
   
   "What hurt can it do you?"
   
   
    "None, none. But I cannot bear it."
   
   
    "It's my belief you hate the sight of the very river."
   
   
     "I — do not like it, father."
   
   
     "As if it wasn't your living! As if it wasn't meat and 
     drink to you!"
   
   
     At these latter words the girl shivered again, and for 
     a moment paused in her rowing, seeming to turn deadly 
     faint. It escaped his attention, for he was glancing 
     over the sterm at something the boat had in tow.
   
   
    "How can you be so thankless to your best friend, 
     Lizzie? The very fire that warmed you when you were 
     a babby, was picked out on the river alongside the 
     coal barges. The very basket that you slept in, the
     tide washed ashore. The very rockers that I put it 
     upon to make a cradle of it, I cut out of a piece of 
     wood that drifted from some ship or another."
   
 
 
   
    Charles Dickens, "Our Mutual Friend", Penguin edition, p. 15
   
 
 
  .
 
   
     Note that in the passage above, the view presented 
     is that the dredgermen dredged coal from alongside 
     the coal barges (either from coal spilled in the 
     water or through theft of coal directly from the 
     coal barges). Once again, Mayhew's information is 
     far more precise: "I know a furrow off Lime'us Point, 
     no wider nor the dredge, and I can go there, and what 
     others can't git anything but stones and mud, I can 
     git four or five bushels o'coal. You see, they lay 
     there, they get in with the set of the tide, and can't 
     git out so easy like." No mention of theft. It is 
     quite possible that some dredgers did steal coal, but 
     it is also evident that some dredgers did not 
     steal coal.
   
 
  .
 
   
     Mayhew also points out that when a dredger gets too 
     old to dredge he still works for a living, at jobs 
     such as "scrapin'" (scraping off the old tar from 
     ships with a scraper). Even in old age, there is no
     sign of begging or theft.
   
 
  .
  
 
   
     Dickens reinforces the idea that Gaffer Hexam "stole"
     money from the dead man's person in another passage.
     Rogue Riderhood accuses Gaffer Hexam:
     
   
 
  .
 
   
    "Since when was you no pardner of mine, Gaffer Hexam Esquire?"
   
   
    "Since you was accused of robbing a man. Accused of 
    robbing a live man!" said Gaffer, with great 
    indignation.
   
   
    "And what if I had been accused of robbing a dead 
    man, Gaffer?"
   
   
    "You COULDN'T do it."
   
   
     "Couldn't you, Gaffer?"
   
   
     "No. Has a dead man any use for money? Is it possible 
     for a dead man to have money? What world does a dead 
     man belong to? 'Tother world. What world does money 
     belong to? This world. How can money be a corpse's? 
     Can a corpse own it, want it, spend it, claim it, miss 
     it? Don't try to go confounding the rights and wrongs 
     of things in that way. But it's worthy of the sneaking 
     spirit that robs a live man."
   
 
 
   
    Charles Dickens, "Our Mutual Friend", Penguin edition, p. 16
   
 
 
  .
  
 
   
     The passage above is in direct opposition to Mayhew's
     statement that "the dredgers cannot by reasoning or 
     argument be made to comprehend that there is anything 
     like dishonesty in emptying the pockets of a dead man." 
     In fact, "They say that anyone who finds a body does 
     precisely the same, and that if they did not do so the 
     police would." Thus, not only do dredgers in general 
     
not feel that emptying the pockets of corpses is 
     dishonest, but they feel as if they are acting 
     
as lawfully as 
     the police. In crafting a conversation where one 
     dredgerman questions another about the morality of 
     removing money from a corpse's pockets, Dickens inserts 
     his own comforting bourgeois view of law and honesty in 
     place of the reality of what law and honesty really mean.
     
   
 
 
  .
 
   
     Dickens portrays Gaffer Hexam both as a man who 
     is capable of reading (which seems unlikely), and as 
     a man who is opposed to formal education. This at least is in line with
     what Mayhew wrote in his interview with a dredgerman,
     whom he quotes as saying "There's on'y one or
     two of us dredgers as knows anything of larnin', and
     they're no better off than the rest. Larnin's no good
     to a dredger, he hasn't got no time to read". 
    
   
 
  .
 
   
     Taking up the bottle with the lamp in it, he 
     held it near a paper on the wall, with the 
     police heading, BODY FOUND. The two friends
     read the handbill as it stuck against the wall, 
     and Gaffer read them as he held the light.
   
   
     "Only papers on the unfortunate man, I see," said 
     Lightwood, glancing from the description of what 
     was found, to the finder.
   
   
     "Only paper."
   
   
     Here the girl arose with her work in her hand, and 
     went out the door.
   
   
     "No money," pursued Mortimer; "but threepence in 
      one of the skirt-pockets."
   
 
 
   
    Charles Dickens, "Our Mutual Friend", Penguin edition, p. 31
   
 
 
  .
 
   
    "One of the gentlemen, the one who didn't speak 
    while I was there, looked hard at me. And I was 
    afraid he might know what my face meant. But 
    there! Don't mind me, Charley! I was all in a 
    tremble of another sort when you owned to your 
    father you could write a little."
   
   
    "Ah! But I made believe I wrote so badly, that it 
    was odds if any one could read it. And when I wrote 
    slowest and smeared out with my finger most, father 
    was best pleased, as he stood looking over me."
   
 
 
   
    Charles Dickens, "Our Mutual Friend", Penguin edition, p. 36
   
 
 
  .
 
   
     Upon what sources did Dickens draw, in the creation of
     the character of Gaffer Hexam? Although there is no direct
     evidence that Dickens was familiar with the work of Henry
     Mayhew, it is difficult to believe that Dickens was unaware
     of it.
    
   
 
  .
 
 
   
     ... Mayhew's interviews with London street folk were well 
    enough known for Dickens to have been aware of them whether 
    he knew Mayhew or not. Mayhew first told well-off readers of 
    the shifts by which the poor of London stayed alive from one 
    day to the next in the Morning Chronicle in 1849-1850. 
    The work appeared in a bewildering variety of amended, 
    augmented, edited, and reorganized editions during the next 
    dozen years and more. ... [T]he final version of the work was 
    printed in 1864 and again in 1865. Dickens was writing 
    Our Mutual Friend in 1864 and 1865; it would be strange 
    if he did not know something at least about material so 
    relevant to his interests ...11 
   
 
  .
  .
 
   
     Three interests of Dickens are relevant here: his affection
     for the Thames, his fascination with the work of the police, 
     and a longstanding interest in drowning.12  
    
   
 
  .
 
   
    Harlan Nelson has studied the relationship between 
    Henry Mayhew's "London Labour and the London Poor"
    and Charles Dickens' "Our Mutual Friend", and
    has noticed other striking coincidences, as follows: 
   
 
  .
 
 
   
   [T]he relationship with 
   London Labour and the London Poor becomes
   still more plausible on the discovery of two other 
   passages in Mayhew. One contains touches suggesting 
   Gaffer Hexam, the dredgerman (river scavenger) in 
   Our Mutual Friend, touches that include 
   distinct verbal reminisces and parallel details. 
   The other is an extensive section on London dustmen 
   and the garbage they collected, matter that 
   (considering the use made of dust and the dust trade 
   in Our Mutual Friend, certainly would have 
   caught Dickens's eye, if indeed it was not what drew
   his attention to the book in the first 
   place.13
   But there is yet another circumstance that argues for 
   the relationship I have suggested between
   London Labour and the London Poor and 
   Our Mutual Friend. In a work running to 
   nearly six hundred closely printed pages, the 
   passage about the dredgermen occurs only four pages 
   after the one dealing with the old 
   woman14, and 
   only nine pages before the section on dust begins; 
   so that not only does a methodical reader, but a 
   browser, or a skimmer, or a novelist looking for 
   material, would be likely to run across all of them.
   It was while browsing, in fact, that I discovered 
   these passages myself.15 
   
 
  
  Conclusion
  
 
   
    In conclusion: it does appear that Dickens has at least
    borrowed ideas about dredgermen from the research that 
    Henry Mayhew published several years before Dickens 
    published "Our Mutual Friend", but not quite.
    Dickens replaced much of the facts found by Mayhew
    with Dickens' own bourgeois imagination about law,
    morality, and education: ideas with which Dickens was
    more comfortable.

   A "waterman" is licensed to carry passengers. 
   A "lighter" carries goods or baggage, only. A 
   "dredgerman's" boat is equipped with grappling 
   hooks, and ropes and typically carries scavenged 
   coal, bones, rope, metal or any other object 
   with value, including dead bodies.

   Mayhew's dredgers pick up many things besides 
   bodies—finding a body, which means a fixed fee
   ("inquest money") and perhaps a reward, is occasionally 
   and outside the routine of their regular business.
   Dickens's Hexam seems to have little interest in anything 
   else. "Dickens's OUR MUTUAL FRIEND and Henry Mayhew's

     "[Dickens] had a preoccupation with the river, and 
    drowning, that came near being an obsession: not 
    to speak of its role in his fiction, it appears 
    in a number of his periodic articles. In one of these, 
    "Down with the Tide" (Household Words, February 5, 
    1853...), the subject is handled more lightly than usual, 
    even whimsically. But that article interests me just here 
    for another reason, too. It is one of a series Dickens did 
    on the police, whose work fascinated him and whose 
    expertise drew his admiration. In this one Dickens reports 
    on a river patrol he took with the Thames Police. We get 
    an interview with the toll collector at Waterloo Bridge, 
    full of macabre drollness (the man's cheerful precision 
    about the habits of prospective suicides), and an account 
    of the various sorts of scavengers that the police keep an 
    eye on and among these, Dickens gives some space to dredgermen. 
    But there is not a word about their work of recovering 
    bodies, or about their peculiar perquisites—omissions 
    doubly odd if Dickens knew about these matters, considering 
    his persistent interest in drownings, and the prominence of 
    suicide by drowning in this particular piece.
   
  .
 
    "But having written about dredgermen himself Dickens would 
    probably notice them the more readily later in the writings 
    of others; and their macabre salvage activity, as reported 
    by Mayhew, would certainly recommend them to his 
    attention." [Ibid., p. 219]
