Recall that this metrical scansion does not imply that of is necessarily spoken with more emphasis than sweet, only that these fill ictic and nonictic positions, respectively.
The top line represents his single-line scansion from 1995, and the lower lines uses his original 2-line system of 1982 (these are "theoretically" identical, only "graphically" different).
Miller offers tour-de-force comparative readings... threading together the world-historical with the personal, poetics with the political, and wielding the instruments of scansion as deftly as a surgeon.
Rhyming stories are notoriously difficult to write, but here the scansion works and the rhyme (both internal and end rhymes) makes the story a delight to read out loud.
