The structure is very repetitive, with a layout of four-line stanzas with even line lengths, which gives the visual impression of solid blocks and chunks of text.
Link to the traditional association between masculinity and strength, with this layout demonstrating this quality through its consistency and regular shape.
Themes
Disappointment
Labour
Social class
Masculinity
"even the men; very powerful men; very ruminative and silent men ignoring me"
Presumptuous narrator - offended tone when the workers probably don't even realise he is there
'Ruminative' - lack of thoughtfulness - suggests they are slow - has links to cattle
Repetition of 'men' symbolises how big and strong they are
Poet is watching men who are very different to him - doing manual labour where he does poetry
"Speech was not something to interest them... all monosyllables"
They don't use words like him as he is a poet - narrator doesn't understand them and is offended by it - gathers an air of superiority
Their lack of speech contrasts narrators rambling
"ladder by the waters edge"
First reference to water motif
Links to the idea of the hidden depth of peoples lives - maybe even depths of society
The workers are on the lowest rung of the ladder
"these men were up against a great difficulty I cannot say what. Every one of the monsters was silent on the subject"
Narrator is being passive-aggressive - feels superior
Use of the adjective 'monster' dehumanises the workers - refers to their physical strengths
Also gives a sense of detachment - the narrator sees no link between himself and the workers
"leaned on the iron rail to gaze down like a mystic into the water"
Poet is confused by the men - supernatural
Even people who are inarticulate, who favour practical skill have a deeper inner life that others won't understand no matter their intelligence
Motif of water - acts as a way of discussing the Marxist perspective - argued that the water is a metaphor for the bottom of the social ladder
Looking into the water is an extended metaphor for social heirarchy
"the foreman, and the most original thinker... with a heavy kind of majesty"
Term 'original thinker' is usually associated with intellect and philosophy - applying it to the foreman is amusing - narrator is mocking his lack of education
Suggests that because he is higher in the ranks he is therefore more educated and therefore more deserving of credit than the others
Mocking is continued through 'heavy kind of majesty'
"That left the pile still in mid-air, and me of course"
Links to the changing ideas of men - they know what they were supposed to be but with societal changes, they are now not as sure
'pile still in mid-air' could be a metaphor for life's uncertainty and irresolution - the significance of the title becomes clear
Forms a conclusion that makes sense and a resolution that resolves nothing
