The opening lines of Robert Frost's 'After Apple Picking' read:
My long two-pointed ladder's sticking through a tree
Toward heaven still,
And there's a barrel that I didn't fill
Beside it, and there may be two or three
Apples I didn't pick upon some bough.
But I am done with apple-picking now.
The poem establishes the relationship of the concrete situation of apple-picking to the abstract one of spiritual purpose in the first two lines. I can understand the purpose of a ladder on both levels: in the first place, some kind of ladder is necessary to pick apples, at least before the invention of the so-called cherry-picker; in the second place, a ladder brings a man closer to heaven, and can perhaps represent man's own efforts to approach the divine.
Why a 'long two-pointed' ladder, though? Are there ladders with more or fewer points?
Metrically, I can see how opening the poem with such heavily stressed words helps to connect us to the speakers toil. Here is how I scan the first line: 'my long two point ed lad der's stick ing through a tree'
Is there a reason besides rhythm that the ladder should be given the adjective 'two-pointed'? The adjective 'long' makes sense on the concrete and abstract levels, but 'two-pointed' sticks in my eyes...
