This is thrird stanza from "To Autumn" by John Keats.

: "Where are the songs of Spring? Ay, where are they? Think not of them, thou hast thy music too, While barred 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 red-breast whistles from a garden-croft; And gathering swallows twitter in the skies. "
