3. Commentary:

(a)  Line 98: On Chapman’s Homer:    not a misprint

A reference to the title of Keats’ famous sonnet (often quoted in America) which, owing to a printer’s absent-mindedness, has been drolly transposed, from some other article, into the account of a sports event. For other vivid misprints see note to line 802.

 (b) Line 782: your poem

 An image of Mont Blanc’s "blue-shaded buttresses and sun-creamed domes" is fleetingly glimpsed through the cloud of that particular poem which I wish I could quote but do not have at hand. The "white mountain" of the lady’s dream, caused by a misprint to tally with Shade’s "white fountain," makes a thematic appearance here, blurred as it were by the lady’s grotesque pronunciation.

(c) Line 803: a misprint

 Translators of Shade’s poem are bound to have trouble with the transformation, at one stroke, of "mountain" into "fountain": it cannot be rendered in French or German, or Russian, or Zemblan; so the translator will have to put it into one of those footnotes that are the rogue’s galleries of words. However! There exists to my knowledge one absolutely extraordinary, unbelievably elegant case, where not only two, but three words are involved. The story itself is trivial enough (and probably apocryphal). A newspaper account of a Russian tsar’s coronation had, instead of korona (crown), the misprint vorona (crow), and when next day this was apologetically "corrected," it got misprinted a second time as korova (cow). The artistic correlation between the crown-crow-cow series and the Russian korona-vorona-korova series is something that would have, I am sure, enraptured my poet. I have seen nothing like it on lexical playfields and the odds against the double coincidence defy computation.
(d) The actual note to which CK refers the reader, line 802: mountain

Where was I? Yes, trudging along again as in the old days with John, in the woods of Arcady, under a salmon sky...."Well," I said gaily, "what were you writing about last night, John? Your study window was simply blazing."..."Mountains," he answered. The Bera Range, an erection of veined stone and shaggy firs, rose before me in all its power and pride... and would I mind very much if we started to go home — though it was only around nine — so that he could plunge back into his chaos and drag out of it, with all its wet stars, his cosmos?...How could I say no? That mountain air had gone to my head: he was reassembling my Zembla!

* -  Line 662: Who rides so late in the night and the wind.: "This line, and indeed the whole passage (lines 653-664), allude to the well-known poem by Goethe about the erlking, hoary enchanter of the elf-haunted alderwood, who falls in love with the delicate little boy of a belated traveler. One cannot sufficiently admire the ingenious way in which Shade manages to transfer something of the broken rhythm of the ballad (a trisyllabic meter at heart) into his iambic verse:
