An Ant went to the bank of a river to quench its thirst, and, being carried away by the rush of the stream, was on the point of being drowned. A Dove, sitting on a tree overhanging the water, plucked a leaf, and let it fall into the stream close to her. The Ant, climbing on to it, floated in safety to the bank. Shortly afterwards a bird catcher came close and stood under the tree, and laid his lime-twigs for the Dove, which sat in the branches. The Ant, perceiving his design, stung him in the foot. He suddenly threw down the twigs, and thereupon made the Dove take wing.
The grateful heart will always find opportunities to show its gratitude.
