The Ant and the Dove
An ant went to a fountain to quench his thirst and, tumbling in, was almost drowned. But a dove that happened to be sitting on a neighboring tree saw the ant's danger and, plucking off a leaf, let it drop into the water before him. The ant mounting upon it, was presently wafted safely ashore.
Just at that time, a fowler was spreading his net and was in the act of ensnaring the dove, when the ant, perceiving his object, bit his heel. The start this gave the man made him drop his net and the dove, aroused to a sense of her danger, flew safely away.
One good turn deserves another.
