A hungry Fox coming into a vineyard where there hung delicious
clusters of ripe Grapes, his mouth watered to be at them; but they
were nailed up to a trellis so high, that with all his springing and
leaping he could not reach a single bunch. At last, growing tired and
disappointed, Let who will take them! says he, they are but green and
sour; so I’ll e’en let them alone.
