The Travelers and the Plane-Tree

TWO TRAVELERS, worn out by the heat of the summer's sun, laid
themselves down at noon under the widespreading branches of a
Plane-Tree.  As they rested under its shade, one of the Travelers
said to the other, "What a singularly useless tree is the Plane!
It bears no fruit, and is not of the least service to man."  The
Plane-Tree, interrupting him, said, "You ungrateful fellows! Do
you, while receiving benefits from me and resting under my shade,
dare to describe me as useless, and unprofitable?'
