There were ten thousand thousand fruit to touch, Cherish in hand, lift down, and not let fall. (lines 30-31)
The root of the speaker's anxiety about falling doesn't become clear until near the end of the poem, when he reveals that he has been trying not to let apples fall and become worthless. What is the effect of Frost's decision to delay the telling of this small but very important detail? These lines make a careful reader want to go back and look at lines 13-16.
Or just some human sleep. (line 42)
Is the speaker disappointed that he will not be hibernating like the woodchuck? Or is he maybe relieved that he doesn't have to embark on the "long sleep," i.e., death? Finally, why would he think that he would have any kind of sleep besides normal, "human sleep"? Remember that his day has been filled with "strangeness," and this funny mood might lead him to entertain strange new possibilities.
