sees loose comparisons to "Rime of the Ancient Mariner" in Whitman's poem (pg 57). Is the San Francisco a ghost that haunts him?
Looking at the footnotes, perhaps it's a cultural ghost of sorts - like the memory of a tragedy in a particular region? The Coleridge tie is
interesting - it suggests that somewhere in this passage there also lies a warning. But of what?
perhaps a warning of ego/arrogance. Perhaps, despite Whitman's idea the universe is balanced, not to underestimate it or its nature.
