What are some literary and figurative devices used in "Birches" by Robert Frost?

Like most of Robert Frost's poems, "Birches" uses a steady
meter, in this case a classic "blank verse" of 10 syllables per line.   Frost once said
that writing poetry without a set meter (free verse) would be like playing tennis
without a net.

Some of the figurative devices in this poem
are as follows.

a) Metaphor
(comparisons that do not use the word "like" or
"as"):

the stir cracks and crazes their
enamel.

(The branches of birch trees are not made
of enamel, of course.  The poet is comparing their hard, iced-over surface to
enamel.)

Soon the sun’s warmth makes them shed
crystal shells
Shattering and avalanching on the snow crust—
Such
heaps of broken glass to sweep away

(The poet
compares bits of broken ice to "heaps of broken glass".)

b)
Alliteration (The repetition of initial consonant
sounds)

They click upon themselves
As
the breeze rises, and turn many-colored
As the stir cracks and crazes their
enamel.
Soon the sun’s warmth makes them shed crystal
shells
Shattering and avalanching on the snow
crust—

(In these 5 lines, a total of 6 words begin
with a hard "c" sound.  Perhaps the poet wants to imitate the clicking of the
ice-covered branches, in which case it is an example of
onomatopoeia.)

c) Simile
(Comparison using the word "like" or
"as")

trailing their leaves on the
ground
Like girls on hands and knees that throw their
hair
Before them over their heads to dry in the
sun.

d) Personification
(speaking about inanimate objects and concepts as if they were
human)

I was going to say when Truth broke
in
With all her matter of fact about the ice
storm,

("Truth" is referred to as a female person
who interrupts one's thoughts.)

e)
Anaphora (the repetition of words or
phrases)

One by one he subdued his father’s
trees
By riding them down over and over again
Until he took the
stiffness out of them,
And not one but hung limp, not one was
left
For him to conquer. He learned all there was
To learn about not
launching out too soon
And so not carrying the tree away
Clear to
the ground.

(In this little section, the words
"one" and "not"  are used 4 times each.)
