In the draft, the section of Part III dealing with Tireias, the typist and the young man carbuncular had 17 stanzas of 4 lines each, all rhymed ABAB.
This Tireias section consists of the lines
215) At the violet hour, when the eyes and back
256) And puts a record on the gramophone.
The original 68 lines underwent heavy editing to become the final 42. Some stanzas were deleted completely while others had lines removed. Some lines were changed and the ending words changed or removed, including the rhyming word. The rhyming pattern was not restored by Eliot. This was undoubtedly because of Ezra Pound's notation written upon the page
"verse not interesting enough as verse to warrant so much of it."
