THE GRASSHOPPER AND CRICKET (BY JOHN KEATS)
The poetry of earth is never dead:
When all the birds are faint with the hot sun,
And hide in cooling trees, a voice will run
From hedge to hedge about the new-mown mead;
That is the Grasshoppers--he takes the lead
In summer luxury,--he has never done
With his delights; for when tired out with fun
He rests at ease beneath some pleasant weed.
The poetry of earth is ceasing never:
On a lone winter evening, when the frost
Has wrought a silence, from the stove there shrills
The Crickets song, in warmth increasing ever,
And seems to one in drowsiness half lost,
The Grasshoppers among some grassy hills.
