What about page 41 before 93 instead of 23? The poem fragment is actually the previous part of that poem. (https://www.poetryloverspage.com/poets/kipling/mary_gloster.html https://www.poetryloverspage.com/poets/kipling/mary_gloster....). Although the rest of the text outside the poem seems to match less... I imagine piecing together these literary references would have been much harder in the 30s compared to now where you can just google them, and ctrl-f the whole text of the book.
