What is to be the high moment of their “Shakespearean Theater”? (CH 20-23)

From the text:

"Hamlet's soliloquy, you know; the most celebrated thing in Shakespeare. Ah, it's sublime, sublime! Always fetches the house. I haven't got it in the book—I've only got one volume—but I reckon I can piece it out from memory. I'll just walk up and down a minute, and see if I can call it back from recollection's vaults."
