Bliss William Carman - Summer Storm

THE hilltop trees are bowing
Under the coming of storm.
The low gray clouds are trailing
Like squadrons that sweep and form,
With their ammunition of rain.
Then the trumpeter wind gives signal
To unlimber the viewless guns;
The cattle huddle together;
Indoors the farmer runs;
And the first shot lashes the pane.
They charge through the quiet orchard;
One pear tree is snapped like a wand;
As they sweep from the shattered hillside,
Ruffling the blackened pond,
Ere the sun takes the field again.
