Which two lines in this excerpt from John Keats's "Ode to Autumn" reflect the theme of growth and maturation? 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-eves 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’er-brimm’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 twined flowers: And sometimes like a gleaner thou dost keep Steady thy laden head across a brook; Or by a cider-press, with patient look, Thou watchest the last oozings, hours by hours.
