"Sparkling chips of rock..."
See in text (To a Steam Roller)
This line offers an example of the speaker’s attentiveness to the world. The “particles” mentioned in the previous stanza become “sparkling chips of rock,” a vivid image conveyed through rich sounds. Note the consonance in particular—the repeated s, p, r, and k sounds. This is an example of language that brings us closer to the world through sound and detail, rather than cloaking it in abstract ideas.
