The Crow and the Pitcher
A Crow, half-dead with thirst, came
upon a Pitcher which had once been full of water; but when the Crow put its
beak into the mouth of the Pitcher he found that only very little water was
left in it, and that he could not reach far enough down to get at it. He
tried, and he tried, but at last had to give up in despair. Then a thought
came to him, and he took a pebble and dropped it into the Pitcher.
Then he took another pebble and dropped it into the Pitcher.
Then he
took another pebble and dropped that into the Pitcher. . . . . etc etc .
At last the water came up near the rim. After a few more pebbles the crow was able to quench his thirst and save his life.
Moral: Little by little does the job.
