Part X contains nineteen lines, an unusual number of lines for a rhyming form poem. The rhyme scheme is a complex abbacccddeeffgghhif with the penultimate line having no other that rhymes with it, and the final line rhyming with one six lines back. The rhythm is irregular, staccato at times--the eleventh line even has six feet! One imagines that Wordsworth did not choose this structure, but that it flowed from his pen rapidly and exuberantly and perhaps without thought as his Ode was coming to an end.
The message is still one of hope and optimism--that it is possible to capture the naive wonder that children find in nature, and that it is possible, with perseverance, to harness this ability to limit the anxiety and care that comes with the responsibilities of adulthood. The poem reads as a hymn to this concept--the opening line particularly evokes Psalm 96.
