The Crow and the Pitcher
A Crow, half dead by 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 that into the Pitcher. [The Crow dropped pebble after pebble into the Pitcher until] at last, at last, he saw the water mount up near him, and after casting a few more pebbles he was able to quench his thirst and save his life. Little by little does the trick.
