Blueberries by Robert Frost:
'You ought to have seen what I saw on my way To the village, through Mortenson's pasture to-day: Blueberries as big as the end of your thumb, Real sky-blue, and heavy, and ready to drum In the cavernous pail of the first one to come! And all ripe together, not some of them green And some of them ripe! You ought to have seen! '
