Ode to Autumn 
by John Keats

Season of mists and mellow fruitfulness, 
Close bosom-friend of the maturing sun; 
Conspiring with him how to load and bless 
With fruit the vines that round the thatch-eaves run; 
To bend with apples the moss'd cottage-trees, 
And fill all fruit with ripeness to the core; 
To swell the gourd, and plump the hazel shells 
With a sweet kernel; to set budding more, 
And still more, later flowers for the bees, 
Until they think warm days will never cease; 
For Summer has o'erbrimm'd their clammy cells. 

Who hath not seen thee oft amid thy store? 
Sometimes whoever seeks abroad may find 
Thee sitting careless on a granary floor, 
Thy hair soft-lifted by the winnowing wind; 
Or on a half-reap'd furrow sound asleep, 
Drowsed with the fume of poppies, while thy hook 
Spares the next swath and all its twinèd flowers: 
And sometimes like a gleaner thou dost keep 
Steady thy laden head across a brook; 
Or by a cyder-press, with patient look, 
Thou watchest the last oozings, hours by hours. 

Where are the songs of Spring? Ay, where are they? 
Think not of them, thou hast thy music too,— 
While barrèd clouds bloom the soft-dying day 
And touch the stubble-plains with rosy hue; 
Then in a wailful choir the small gnats mourn 
Among the river-sallows, borne aloft 
Or sinking as the light wind lives or dies; 
And full-grown lambs loud bleat from hilly bourn; 
Hedge-crickets sing; and now with treble soft 
The redbreast whistles from a garden-croft; 
And gathering swallows twitter in the skies.
