Birches

below is a partial excerpt from 
Robert Frost's poem Birches

When I see birches bend to left and right

Across the lines of straighter darker trees,

I like to think some boy's been swinging them.

But swinging doesn't bend them down to stay.

Ice-storms do that. Often you must have seen them

Loaded with ice a sunny winter morning

After a rain. 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--

Such heaps of broken glass to sweep away

You'd think the inner dome of heaven had fallen.

They are dragged to the withered bracken by the load,

And they seem not to break; though once they are bowed

So low for long, they never right themselves:

You may see their trunks arching in the woods

Years afterwards, 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.

—Robert Frost
