A peasant had an apple tree growing in his garden which bore no fruit, but merely served to provide a shelter from the heat for the sparrows and grasshoppers which sat and chirped in its branches.
Disappointed at its barrenness he determined to cut it down, and went and fetched his axe for the purpose.
But when the sparrows and the grasshoppers saw what he was about to do, they begged him to spare it, and said to him, 'If you destroy the tree we shall have to seek shelter elsewhere, and you will no longer have our merry chirping to enliven your work in the garden.'
He, however, refused to listen to them, and set to work with a will to cut through the trunk.
A few strokes showed that it was hollow inside and contained a swarm of bees and a large store of honey.
Delighted with his find he threw down his axe, saying, 'The old tree is worth keeping after all.'

Utility is most men's test of worth.
