    “I'll tell thee everything I can; \
    #h(1em)There's little to relate. \
    I saw an aged aged man, \
    #h(1em)A-sitting on a gate. \
    ‘Who are you, aged man?' I said, \
    #h(1em)‘and how is it you live?' \
    And his answer trickled through my head \
    Like water through a sieve.

    He said ‘I look for butterflies \
    #h(1em)That sleep among the wheat: \
    I make them into mutton-pies, \
    #h(1em)And sell them in the street. \
    I sell them unto men,' he said, \
    #h(1em)‘Who sail on stormy seas; \
    And that's the way I get my bread--- \
    #h(1em)A trifle, if you please.'

    But I was thinking of a plan \
    #h(1em)To dye one's whiskers green, \
    And always use so large a fan \
    #h(1em)That they could not be seen. \
    So, having no reply to give \
    #h(1em)To what the old man said, \
    I cried, ‘Come, tell me how you live!' \
    #h(1em)And thumped him on the head.

    His accents mild took up the tale: \
    #h(1em)He said ‘I go my ways, \
    And when I find a mountain-rill, \
    #h(1em)I set it in a blaze; \
    And thence they make a stuff they call \
    #h(1em)Rolands' Macassar Oil--- \
    Yet twopence-halfpenny is all \
    #h(1em)They give me for my toil.'

    But I was thinking of a way \
    #h(1em)To feed oneself on batter, \
    And so go on from day to day \
    #h(1em)Getting a little fatter. \
    I shook him well from side to side, \
    #h(1em)Until his face was blue: \
    ‘Come, tell me how you live,' I cried, \
    #h(1em)‘And what it is you do!'

    He said ‘I hunt for haddocks' eyes \
    #h(1em)Among the heather bright, \
    And work them into waistcoat-buttons \
    #h(1em)In the silent night. \
    And these I do not sell for gold \
    #h(1em)Or coin of silvery shine \
    But for a copper halfpenny, \
    #h(1em)And that will purchase nine.

    ‘I sometimes dig for buttered rolls, \
    #h(1em)Or set limed twigs for crabs; \
    I sometimes search the grassy knolls \
    #h(1em)For wheels of Hansom-cabs. \
    And that's the way' (he gave a wink) \
    #h(1em)‘By which I get my wealth--- \
    And very gladly will I drink \
    #h(1em)Your Honour's noble health.'

    I heard him then, for I had just \
    #h(1em)Completed my design \
    To keep the Menai bridge from rust \
    #h(1em)By boiling it in wine. \
    I thanked him much for telling me \
    #h(1em)The way he got his wealth, \
    But chiefly for his wish that he \
    #h(1em)Might drink my noble health.

    And now, if e'er by chance I put \
    #h(1em)My fingers into glue \
    Or madly squeeze a right-hand foot \
    #h(1em)Into a left-hand shoe, \
    Or if I drop upon my toe \
    #h(1em)A very heavy weight, \
    I weep, for it reminds me so, \
    Of that old man I used to know--- \
    Whose look was mild, whose speech was slow, \
    Whose hair was whiter than the snow, \
    Whose face was very like a crow, \
    With eyes, like cinders, all aglow, \
    Who seemed distracted with his woe, \
    Who rocked his body to and fro, \
    And muttered mumblingly and low, \
    As if his mouth were full of dough, \
    Who snorted like a buffalo--- \
    That summer evening, long ago, \
    #h(1em)A-sitting on a gate.”
