A thirsty Crow found a tall pitcher with a little water pooled at the very bottom — far below where her beak could reach. She pushed, she tipped, she strained against the heavy clay, but it would not budge, and the water stayed maddeningly out of reach.
She was about to give up when an idea came. One by one, she picked up small pebbles from the ground and dropped them, plink, into the pitcher.
And with each stone, the water rose a little higher.
Pebble after patient pebble, the water climbed the neck of the pitcher until at last it reached the brim — and the clever Crow drank her fill.
The moral
Little by little does the trick — and necessity is the mother of invention.
