What is the poems meaning in "The Wind Begun to Rock the Grass"



The Wind begun to rock the Grass

With threatening Tunes and low--

He threw a Menace at the Earth--

A Menace at the Sky.


The Leaves unhooked themselves from Trees--

And started all abroad

The Dust did scoop itself like Hands

And threw away the Road.


The Wagons quickened on the Streets

The Thunder hurried slow--

The Lightning showed a Yellow Beak

And then a livid Claw.


The Birds put up the Bars to Nests--

The Cattle fled to Barns--

There came one drop of Giant Rain

And then as if the Hands


That held the Dams had parted hold

The Waters Wrecked the Sky,

But overlooked my Father's House--

Just quartering a Tree--

Please be sure about your answer. Thanks!
