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.
